Abstract ：
This work introduces a new strategy of a single-atom nest catalyst, whereby several single atoms are positioned closely, aiming to achieve the dual benefits of high atom-utilization efficiency while avoiding the steric hindrance in the coupling reaction. As a proof of concept, Pt single-atom nests, where the adjacent Pt single atoms are approximately 4 Å apart, are precisely engineered on the TiO2 photocatalyst for photocatalytic non-oxidative coupling of methane. The Pt single-atom nest photocatalyst demonstrates remarkable activity, achieving a C2H6 yield and turnover frequency of 251.6 μmol gcat-1 h-1 and 20 h-1, respectively, representing a 3.2-fold improvement compared to the Pt single-atom photocatalyst. Density functional theory calculations reveal that the Pt single-atom nest can significantly decrease the energy barrier for the activation of both CH4 molecules in the coupling process. © 2024 American Chemical Society.

Abstract ：
Photocatalytic ozonation emerges as an appealing approach for wastewater purification. However, the kinetic constraints associated with the charge separation and the ozone activation hinder the advancement of photocatalytic ozonation systems. Herein, we prepared CeO2 photocatalysts with predominantly exposed {1 1 0}, {1 0 0}, or {1 1 1} facets, highlighting the synergy role of crystal facet and oxygen vacancies in manipulating electron transfer and ozone activation. The CeO2-{1 1 0} catalyst exhibits the best efficiency for phenol mineralization (69%) in photocatalytic ozonation. Ex-situ, Quasi-situ, and In-situ characterization of the CeO2 catalysts reveal that facet engineering in the CeO2 catalysts optimizes the electronic properties of the catalysts, thereby enhancing the separation of photogenerated charge carriers and transfer of electrons and holes, which provides more electrons for O3 activation and promotes the formation of reactive oxygen species (ROS). Moreover, facet modulating leads to a change in the density of surface oxygen vacancies. The increased oxygen vacancy density on the CeO2-{1 1 0} surface accelerates the activation of O3 and the formation of adsorbed oxygen (*O), synergistically boosting the production rate of ROS. The present study offers valuable insights into the design of efficient photocatalysts for wastewater purification. © 2024 Elsevier Inc.

Abstract ：
The construction of photothermal catalysts to provide advanced oxidation ability and stability is a great challenge for eliminating volatile organic compounds (VOCs) during the photothermal catalytic process. Herein, a bimetallic modification method was proposed to synthesize Pd/Fe-TiO2. Under ultraviolet-visible (UV-Vis) light irradiation with the intensity of 610 mW/cm(2), the optimal 0.7 wt% Pd/0.4 wt% Fe-TiO2 catalyst of which surface was detected at the temperature of 165 C can achieve a toluene conversion of 94 % and a CO2 yield of 87 %, respectively. Based on the results of in-situ DRIFTS, quasi-situ EPR, XPS, and O-2-TPD tests, it was found that two distinct types of Pd and Fe active sites not only generated reactive oxygen species (ROS) but also adsorbed toluene and intermediate species, which promoted the degradation of toluene. It is proposed that there be an electron transfer behavior between Fe and Pd nanoparticles, resulting in a synergistic interaction of the two metals. This study shows that creating bimetallic modification catalysts is an efficient method for eliminating VOCs through photothermal catalysis.

Abstract ：
A prepared p -type PdO/n-type TiO2 junction was prepared as the catalyst for photocatalytic hydrogen evolution from formic acid (FA). It was found that PdO/TiO2 exhibited 1298 -fold higher activity than TiO2 under ultraviolet and visible light irradiation at room temperature. Multiple characterization techniques were utilized to demonstrate that doping PdO into TiO2 can regulate the Fermi level of the sample and the adsorption behavior of FA, resulting in different electron transfer behavior between FA and PdO/TiO2 compared to that between FA and TiO2. Oxygen vacancies acted as electron donors to deliver photogenerated electrons from TiO2 to the adsorbed bidentate FA, which increased the electron density on the O atom of FA and led to the formation of activated monodentate FA. This activated FA was more easily oxidized by the holes in PdO generated by visible light, leading to the production of H2 and CO2. The mode of adsorption associated with the Pd2+ site is the key factor in driving this reaction and leading to the reversible electron transfer phenomenon. This study provides a new promising route for the design of photocatalysts for self -decomposition reactions.

Abstract ：
To resolve the pollution flashover problem of insulators, a novel application of nanosized TiO2 film to improve the ceramic insulator performance under contaminated conditions has been successfully developed. Compared with the uncoated insulator, TiO2 -coated insulator exhibits an enhanced self-cleaning performance induced by the photocatalysis and hydrophilicity of TiO2 film in the heavily contaminated surroundings. Moreover, the TiO2 -coated insulator also presents a better electric performance in power-frequency puncture voltage, power-frequency puncture voltage in dielectric oil, wet power-frequency flashover voltage, lightning impulse withstand voltage, and the artificial pollution flashover voltage due to the semi-conducting property of TiO2 film to make the distribution of the electric field more even. The synergy between these two effects helps to promote the performance of TiO2 -coated insulators for anti-pollution flashover. © 2023 WILEY-VCH GmbH.

Abstract ：
负载型金属纳米催化剂由于其优异的光催化性能，被广泛应用于光催化产氢协同胺类氧化偶联合成高附加值亚胺体系。但在反应过程中，金属表面对H原子和亚胺表现出较强的吸附能力，导致了亚胺易于发生自氢化反应而生成仲胺，显著降低了亚胺的选择性。在本文中，我们证实了在Pd/Ti O_2表面构建超薄碳层(Pd/Ti O_2@C)是一种解决上述问题的有效策略。在Pd/Ti O_2表面构筑的超薄碳层可以有效调控H原子和亚胺在其表面的吸附行为，避免了光催化氧化偶联过程中亚胺的自氢化。因此，Pd/Ti O_2@C光催化剂在光催化产氢协同胺类选择性氧化合成亚胺体系中展现出优异的亚胺选择性。本研究提供了一种便捷有效的策略推动负载型金属纳米催化剂在光催化产氢协同合成高附加值产物体系中的应用。

Abstract ：
The electronic and optical properties of ZnO can be modified via the creation of intrinsic defects, especially oxygen and zinc vacancy. For researchers to have a clear understanding of various defects, we summarize different methods that are used to prepare and characterize vacancy defects. In fact, vacancy defects can regulate the Fermi level of ZnO itself and enrich photogenerated carriers, and then act as adsorption sites that are involved in the surface adsorption and photocorrosion reaction processes. Furthermore, defects function as a double-edged sword in regulating photocatalytic performance. It is suggested that preparing zinc oxide with a medium concentration of defects can obtain excellent photocatalytic performance. © 2023 WILEY-VCH GmbH.
