Abstract ：
Angiogenesis provides essential nutrients and oxygen to tumors during tumorigenesis, facilitating invasion and metastasis. Consequently, inhibiting tumor angiogenesis is an established strategy in anti-cancer therapy. In this study, we engineered a dual-function nanosystem with both antiangiogenic and photodynamic properties. We transformed the hydrophobic photosensitizer zinc phthalocyanine (PS) into a hydrophilic form via protein renaturation, resulting in a novel photosensitizer: Monocyte-Activating Polypeptide-II (EMAP-II:PS@NPs). Characterization through dynamic light scattering (DLS) and UV-vis spectroscopy showed that these nano- particles exhibited uniform size and stability, and enhanced solubility. We further demonstrated that EMAP-II: PS@NPs effectively target tumor vascular endothelia causing intracellular photodynamic cytotoxicity. Notably, EMAP-II:PS@NPs achieved effective ablation of solid tumors at significantly reduced dosages of drugs compared to conventional therapies, due to their potent apoptotic effects on light-exposed cells. This study highlights the potential of combining anti-angiogenic activity with phototherapy, paving the way for innovative cancer treatment strategies.

Abstract ：
Single-atom catalysts (SACs) have emerged as a focal point of research in the field of heterogeneous catalysis. This paper reviews the progress in the studies of single atoms as promoters in various catalytic reactions, elucidating their distinctive role in comparison to the dominant active sites. We provide a discussion on the application of single-atom promoters (SAP) within host-guest systems in various catalysts, including metal oxide supported catalysts, molybdenum carbide-based catalysts, bimetallic catalysts, and others. The behavior of SAP is diverse. They often promote the formation of oxygen vacancies for oxide support, leading to local site reconstruction that creates specific reaction route. Moreover, they can also precisely modify the electronic structure of hetero-metal atomic or nanoparticle sites, then regulating the adsorption of reactants or intermediates and catalytic performance. Finally, the potential for the development of SAP is outlined, proposing novel approach for the design of SACs with enhanced activity and stability.

Abstract ：
The local structure of the metal single-atom site is closely related to the catalytic activity of metal single-atom catalysts(SACs).However,constructing SACs with homogeneous metal active sites is a challenge due to the surface heterogeneity of the conventional support.Herein,we prepared two Rh1/CeO2 SACs(0.5Rh1/r-CeO2 and 0.5Rh1/c-CeO2,respectively)using two shaped CeO2(rod and cube)exposing different facets,i.e.,CeO2(111)and CeO2(100).In CO oxidation reaction,the T100 of 0.5Rh1/r-CeO2 SACs is 120 ℃,while the T100 of 0.5Rh1/c-CeO2 SACs is as high as 200 ℃.Via in-situ CO diffuse reflectance infrared Fourier transform spectroscopy(CO-DRIFTS),we found that the proximity between OH group and Rh single atom on the plane surface plays an important role in the catalytic activity of Rh1/CeO2 SAC system in CO oxidation.The Rh single atom trapped at the CeO2(111)crystal surface forms the Rh1(OH)adjacent species,which is not found on the CeO2(100)crystal surface at room temperature.Furthermore,during CO oxidation,the OH group far from Rh single atom on the 0.5Rh1/c-CeO2 disappears and forms Rh1(OH)adjacent species when the temperature is above 150 ℃.The formation of Rh1(OH)adjacentCO intermediate in the reaction is pivotal for the excellent catalytic activity,which explains the difference in the catalytic activity of Rh single atoms on two different CeO2 planes.The formed Rh1(OH)adjacent-O-Ce structure exhibits good stability in the reducing atmosphere,maintaining the Rh atomic dispersion after CO oxidation even when pre-reduced at high temperature of 500 ℃.Density functional theory(DFT)calculations validate the unique activity and reaction path of the intermediate Rh1(OH)adjacentCO species formed.This work demonstrates that the proximity between metal single atom and hydroxyl can determine the formation of active intermediates to affect the catalytic performances in catalysis.

Abstract ：
CO2 hydrogenation to methane is gaining increasing interest as one of the most promising ways to store intermittent renewable energy in the form of chemical fuels. Ni particles supported on CeO2 represent a highly efficient, stable and inexpensive catalyst for this reaction. Herein, Ni-doped CeO2 nanoparticles were tested for CO2 methanation showing an extremely high Ni mass-specific activity and CH4 selectivity. Operando characterization reveals that this performance is tightly associated with ionic Ni and Ce3+ surface sites, while formation of metallic Ni does not seem to considerably promote the reaction. Theoretical calculations confirmed the stability of interstitial ionic Ni sites on ceria surfaces and highlighted the role of Ce-O frustrated Lewis pair (FLP), Ni-O classical Lewis pair (CLP) and Ni-Ce pair sites to the activation of H-2 and CO2 molecules. To a large extent, the theoretical predictions were validated by in situ spectroscopy under H-2 and CO2 : H-2 gaseous environments.

Abstract ：
Two-dimensional molybdenum carbide (2D-Mo2C) is thought to be promising for catalytic hydrogenation of CO2 to CH4, but little is known about its catalytic reaction mechanism. In this work, we investigate the hydrogenation of CO2 to CH4 on 2D-Mo2C using density functional theory. Our calculations show that Mo on the surface can efficiently decompose CO2 to CO and O, and also H2 to H. The hydrogenation of CO produces CHO that is readily deoxygenated to CH, and CH is selectively hydrogenated to produce CH4. Interestingly, the embedded Ir1 on 2D-Mo2C can act as a single-atom promoter to improve the performance of CO2 methanation, while on the other hand maintaining its high selectivity for CH4. This work provides insight into the mechanism of 2D-Mo2C-catalyzed CO2 methanation reactions and suggests a strategy to improve the performance of such catalysts through single-atom promoters. & COPY; 2022 Hydrogen Energy Publications LLC.

In CO oxidation reaction, the T-100 of 0.5Rh(1)/r-CeO2 SACs is 120 degrees C, while the T-100 of 0.5Rh(1)/c-CeO2 SACs is as high as 200 degrees C. Via in-situ CO diffuse reflectance infrared Fourier transform spectroscopy (CO-DRIFTS), we found that the proximity between OH group and Rh single atom on the plane surface plays an important role in the catalytic activity of Rh-1/CeO2 SAC system in CO oxidation. The Rh single atom trapped at the CeO2 (111) crystal surface forms the Rh-1(OH)(adjacent) species, which is not found on the CeO2 (100) crystal surface at room temperature. Furthermore, during CO oxidation, the OH group far from Rh single atom on the 0.5Rh(1)/c-CeO2 disappears and forms Rh-1(OH)(adjacent) species when the temperature is above 150 degrees C. The formation of Rh-1(OH)(adjacent)CO intermediate in the reaction is pivotal for the excellent catalytic activity, which explains the difference in the catalytic activity of Rh single atoms on two different CeO2 planes.

Abstract ：
NiS is deposited on the surface of hexagonal ZnIn2S4 via a hydrothermal method and the as-obtained NiS/ZnIn2S4 nanocomposite shows superior activity for photocatalytic dehydrogenative coupling of amines to produce imines, with simultaneous generation of hydrogen under visible light. The superior performance over NiS/ZnIn2S4 for photocatalytic dehydrogenative coupling of benzylamine to produce N-benzylidenebenzylamine can not only be ascribed to NiS, which acts as a cocatalyst to promote the charge transfer and hydrogen evolution, but also attributed to its strong adsorption toward benzylamine and its relatively weak adsorption toward the product, which is also proved by density functional theory calculations. This study not only provides an efficient, green, and cost-effective strategy to produce imines, but also demonstrates that the adsorption of the photocatalyst toward the reactants and the products is an important issue that should be considered in a photocatalytic reaction.

Abstract ：
In this work, we investigated the methanol steam reforming (MSR) reaction (CH3OH+H2O -> CO2+3H(2)) catalyzed by alpha-MoC by means of density functional theory calculations. The adsorption behavior of the relevant intermediates and the kinetics of the elementary steps in the MSR reaction are systematically investigated. The results show that, on the alpha-MoC(100) surface, the O-H bond cleavage of CH3OH leads to CH3O, which subsequently dehydrogenate-, to CH2O. Then, the formation of CH2OOH between CH2O and OH is favored over the decomposition to CHO and H. The sequential dehydrogenation of CH2OOH results in a high selectivity for CO2. In contrast, the over-strong adsorption of the CH2O intermediate on the alpha-MoC(111) surface leads to its dehydrogenation to CO product. In addition, we found that OH species, which is produced from the facile water activation, help the O-H bond breaking of intermediates by lowering the reaction energy barrier. This work not only reveals the catalytic role played by alpha-MoC(100) in the MSR reaction, but also provides theoretical guidance for the design of alpha-MoC-based catalysts.

Abstract ：
Systematic interrogation of correlative signaling components in their native environment is of great interest for dissecting sophisticated cellular signaling. However, it remains a challenge because of the lack of versatile and effective approaches. Herein, we propose a cell membrane-anchored DNA multitasking processor acting as a "traffic light" for integrated analyses of cellular signal transduction. Enhanced and controllable inhibition of c-Met signaling was achieved by membrane-anchoring of DNA processors. Moreover, the multitasking capability of the DNA processor allowed the monitoring of correlative VEGF secretion induced by c-Met activity regulation directly. By exploiting versatile aptameric nucleic acids, this modular designed DNA multitasking processor dissected how cell surface receptors coordinated with related components in live cells systematically. Therefore, it provides a powerful chemical tool for both fundamental cell biology research and precision medicine applications.
