Abstract ：
Photocatalytic water oxidation half-reaction is a critical bottleneck in achieving efficient overall water splitting using polymeric photocatalysts, primarily due to the lack of efficient water oxidation sites and sluggish reaction kinetics. To address these challenges, a doping engineering strategy is proposed to activate inert carbon atoms as efficient water oxidation sites in poly(heptazine imide) (PHI). Computational analysis revealed that Rb+ dopants can induce in-plane structural distortions in PHI, thereby modulating the electronic structure of carbon atoms. This modulation enhanced the adsorption of *OH intermediates on carbon atoms and significantly reduced the reaction barrier for water oxidation. Furthermore, charge carriers dynamics uncovered that the incorporation of the Rb+ ions into the PHI framework can promote the photoexcited exciton dissociation and induce the holes to migrate to the water oxidation sites. As a result, the Rb-doped PHI achieved an excellent apparent quantum efficiency value of up to 20.4% at 400 nm for water oxidation. This finding offers a new channel for researchers to develop highly efficient polymeric photocatalysts for photocatalytic water oxidation reactions.

Abstract ：
Photosynthesis of H2O2 from O-2 and H2O with inexhaustible sunlight as an energy source is a promising approach. However, the photocatalytic performance of pristine polymeric carbon nitride (PCN) is extremely restrained due to the rapid recombination of photo-generated electrons and holes, and slow surface reaction processes. Herein, a new strategy is developed to rationally integrate N, S-co-doped carbon (C-NS), and CoS2 on cyano-rich PCN (PCN-Cy) for photosynthesis of H2O2 under ambient conditions. The engineering with cyano groups (electron-withdrawing groups) promotes the bulk charge separation of PCN. Experimental results reveal that the CoS2 co-catalyst not only serves as an electron acceptor to extract charges from the bulk but also functions as an active site to promote the 2-e(-) ORR process. Besides, the N, S-co-doped carbon performs as an electron channel to promote migration of charges at the interface of PCN-Cy and CoS2. Accordingly, the as-synthesized cyano-rich PCN photocatalyst integrated with N, S-co-doped carbon and CoS2 exhibits a remarkable activity of 321.9 mu m h(-1) for photocatalytic production of H2O2, which is 44.9 times higher than that of the pristine PCN.

Abstract ：
Poly(triazine imide) (PTI) holds significant promise for photocatalytic CO2 reduction by addressing the limitations of conventional carbon nitrides. However, its practical application remains constrained by a narrow visible-light absorption. Herein, we report a barbituric acid (BA)-mediated copolymerization strategy to engineer pi-electron delocalization within the triazine framework for broadening light-harvesting spectrum and optimizing charge carrier transport. Under visible light irradiation (lambda >= 400 nm), the optimized PTI-BA(1.0) photocatalyst achieves a CO evolution rate of 10 mu mol h(-1) (333 mu mol g(-1) h(-1)) with 95% selectivity, representing a 5-fold enhancement over pristine PTI. Remarkably, the apparent quantum efficiency reaches 13.6% at 365 nm, underscoring its superior CO2 photoconversion capability. Mechanistic investigations via in situ diffuse reflectance infrared Fourier transform spectroscopy and density functional theory calculations elucidate the energetically favorable pathways for CO2 activation, reduction and CO desorption. This work not only provides a rational design strategy for modulating the optoelectronic properties of crystalline carbon nitride but also advances the development of high-performance photocatalysts for sustainable CO2 conversion.

Abstract ：
Photocatalytic water splitting emerges as a transformative technology for sustainable hydrogen energy production. However, reliance on sacrificial hole scavengers (e.g., triethanolamine) in conventional systems leads to significant underutilization of oxidative potential and increases the cost of hydrogen production. Coupling photocatalytic hydrogen evolution with the oxidative valorization of biomass-derived polyols establishes a dual-functional system that simultaneously enhances solar energy conversion efficiency and creates economic value through the coproduction of high-value-added chemicals. In this study, the energy band structure and charge carrier behaviors of poly (heptazine imides) are modulated by salt-melt polymerization in the presence of different gas flow atmospheres (e.g., NH3, CO2, N2). Accordingly, the optimum potassium poly (heptazine imide) synthesized in the presence of CO2 presents excellent performance for visible-light photocatalytic hydrogen production (apparent quantum yield(AQY) = 44% under λ = 420 nm) coupled with glycerol valorization for selective synthesis of dihydroxyacetone (DHA, ∼ 146 µmol of DHA per hour). This study provides new insights into the rational design of carbon nitride photocatalysts, as well as the concurrent achievement of hydrogen evolution coupled with the production of high-value-added chemicals. © 2025 Wiley-VCH GmbH.

Abstract ：
Photocatalytic hydrogen peroxide (H2O2) production using conjugated polymers as photocatalysts is a green and sustainable approach to synthesizing H2O2. Nevertheless, the efficiency is still hindered by the inefficient charge separation and transfer dynamics. Herein, a series of coplanar 2D ladder polymers with different substituents were reported as metal-free photocatalysts for artificial photosynthesis of H2O2. Detailed experimental and theoretical investigations reveal that the coplanar 2D skeleton and strong electron-withdrawing substituents could profoundly facilitate charge separation and transfer. Possessing these notable merits, the cyano-substituted polymer (PAE-CN) exhibits remarkable photocatalytic performance on H2O2 evolution. This study contributes to the development of effective polymer photocatalysts tailored for potential applications in artificial photosynthesis.

Abstract ：
Lattice oxygen (LO)-mediated photothermal dry reforming of methane (DRM) presents a promising approach to syngas production. However, realizing high DRM efficiency and durability remains challenging due to the difficulty in activating LOs in catalysts. Herein, we demonstrate that partially substituting Fe sites in perovskite ferrite (LaFeO3) by Mn triggers LOs, bestowing the catalyst with superior activity and stability for photothermal DRM after modification with Ru. The Mn exchange induces a charge transfer from La to Mn, which combined with the incoming photoexcited electrons reconstructs the perovskite's electronic structure, weakening the La-O-Mn bonds and facilitating the LO migration. Meanwhile, photogenerated holes migrate to surface LOs, further enhancing their reactivity to mediate DRM. Under light irradiation, the catalyst exhibits an outstanding syngas production rate (H2: 42.89 mol gRu -1 h-1, CO: 54.92 mol gRu -1 h-1) while stably operating over 150 h. It also achieves a methane turnover frequency of 0.9 s-1 and a light-to-chemical energy efficiency of 15.3%, setting a benchmark for light-driven DRM performance. This work underscores the significance of exact site doping in metal oxides to fine-tune LO activity, providing valuable guidance for fabricating efficient catalysts for solar-powered redox reactions proceeded via the light-supported Mars-van Krevelen mechanism.

Abstract ：
Elevating the long-wavelength activation of photocatalysts represents a formidable approach to optimizing sunlight utilization. Polythiophene (PTh), although renowned for its robust light absorption and excellent conductivity, is largely overlooked for its potential as a photocatalyst due to the swift recombination of photogenerated charge carriers. Herein, we unveil that the strategic introduction of an aromatic ring containing varying nitrogen content into PTh instigates polarized charge distribution and facilitates the narrowing of the band gap, thereby achieving efficient photocatalytic activities for both hydrogen and hydrogen peroxide generation. Notably, the best sample, PTh-N2, even demonstrates photocatalytic activity in the red light region (600-700 nm). This study offers a promising avenue for the development of polymer photocatalysts with efficient photocatalytic performance for red light-induced photocatalysis.

Abstract ：
As a crystalline allotrope of carbon nitrides, poly (heptazine imide) (PHI) exhibits great potential for photocatalytic reforming of biomass-derived alcohols. However, its activity is greatly constrained due to insufficient charge migration and severe non-radiative recombination. To address this issue, PHI with high interlayer stacking orderliness is fabricated through a facile ion exchange strategy. Characterizations reveal that rational modification of the interlayer stacking mode of PHI could efficiently suppress non-radiative recombination and improve charge transfer efficiency. Accordingly, the optimal sample exhibits high photocatalytic reforming activity for H2 evolution, which is up to 2.16 mmolg-1h-1, and with a quantum efficiency reaches 26.7% at 400 nm.

Abstract ：
Polymeric carbon nitrides (PCNs), usually the melon phase, have been extensively applied as photocatalysts for CO2 reduction; however, their performance is still unsatisfactory. The condensed allotrope, namely, poly(triazine imide) (PTI) with extended conjugation and a crystallized structure, indeed holds more favorable compositional and structural advantages for photocatalytic CO(2)reduction but remains to be fully exploited. Herein, hexagonal prism-shaped PTI crystals were synthesized and developed as a high-performance photocatalyst for CO2 reduction. With Co(bpy)(3) (2+) as a cocatalyst, the PTI crystals exhibit a CO evolution rate of 44 mu mol h(-1) (i.e., 1467 mu mol g(-1) h(-1)) with 93% selectivity, markedly superior to that of the melon counterpart. Moreover, PTI crystals manifest an apparent quantum efficiency of 12.9% at 365 nm, representing the state-of-the-art value by PCN photocatalysts for CO2-to-CO reduction without using noble metals. The surface pyridine N species of PTI are exposed as active sites to dominate CO2 activation and conversion, which, together with the high crystallinity to facilitate charge separation and transport, endows high CO2 reduction efficiency. In situ diffuse reflectance infrared Fourier transform spectroscopy determines the key intermediates during the CO2 reduction reaction and, consequently, constructs the possible reaction mechanism.

Hollow carbon nitride spheres with a well-designed architecture and excellent optical properties serve as promising polymers for solar fuel production. In this study, carbon-rich hollow carbon nitride nanospheres were rationally designed for photocatalytic hydrogen peroxide production. Experimental results revealed that the doping of carbon species in the heptazine unit enhanced light absorption and promoted charge separation and transport. Accordingly, the optimized carbon-rich hollow carbon nitride nanospheres exhibited significantly enhanced photocatalytic performance for solar-driven hydrogen peroxide production and Cr(vi) reduction in comparison with pristine polymeric carbon nitride and hollow carbon nitride nanospheres.
