Summary: Using a combination of non-noble metal atoms and defect-engineered transition metal dichalcogenide (TMD) monolayers, new types of single-atom catalysts for electrochemical CO2RR can be designed, exhibiting better catalytic performance and selectivity. Applying suitable biaxial tensile strains on defect-engineered TMDs can significantly reduce the overpotentials of non-noble metal atoms, with the vacancy defects and charge transfer playing a crucial role in improving catalytic activity.

Summary: In this study, the strong metal-support interaction (SMSI) phenomenon for supported Ni/CeO2 catalysts with different CeO2 nanomorphologies was systematically explored. The degree of encapsulation of Ni particles originating from the SMSI effect was found to be positively correlated with the CO2 hydrogenation activity. Quasi in situ XPS and in situ DRIFTS techniques were used to reveal the relevant species and reaction pathways. These findings provide a fundamental strategy for tailoring catalytic performance by adjusting the support surface structure.

Summary: In this study, aluminum oxide (Al2O3) and titanium dioxide (TiO2)-supported iridium-ruthenium (IrRu) catalysts were synthesized and their catalytic performance in CO-assisted NO reduction was investigated. The results showed that IrRu bimetallic particles were well-alloyed on both supports, with TiO2 exhibiting a smaller size due to strong interactions with the metal. Interestingly, despite its larger particle size, IrRu/Al2O3 showed more efficient selective conversion of NOx to N2 compared to IrRu/TiO2. Mechanistic analysis suggested that the defect-free flat surface structure of the IrRu alloy contributed to its superior performance. The metal-support interfaces were found to be inactive regardless of their interaction strength.

Summary: In this study, the photocatalytic oxidative coupling of methane (OCM) over transition-metal-loaded ZnO photocatalysts was systematically investigated. A 1 wt% Au/ZnO catalyst exhibited remarkable C-2-C-4 hydrocarbon production rate and selectivity under light irradiation. The selectivity towards C-C coupling products strongly depends on the metal type and its interaction with ZnO. The findings suggest that the d-sigma center can be a suitable descriptor for predicting product selectivity during OCM over metal/ZnO photocatalysts.

Summary: Enormous advances have been made in photothermal catalysis, but temperature assessment remains controversial in most photothermal catalytic systems. We revealed the phenomenon of temperature determination bias in gas-solid photothermal catalytic systems, which has been overlooked in most cases. To avoid temperature bias interference, we developed a universal protocol for reliable temperature evaluation by optimizing the reaction system. This study presents a functional and credible practice for temperature detection and emphasizes the effects of temperature differences in gas-solid photothermal catalysis.

Summary: This study measured the actual reaction temperature of photothermal ammonia synthesis over carbon-supported Ru catalyst using Le Chatelier's principle, and found that the activation energy for photothermal catalysis was much lower than thermocatalysis. This was attributed to hot-electron injection reducing the energy barriers for N2 dissociation and intermediates hydrogenation, while also suppressing carbon support methanation. The catalyst exhibited outstanding operational stability over 1000 hours. This work provides new insights into the effects of hot electrons in ammonia synthesis and guides the design of high-performance photothermal catalysts.

Summary: Strong metal-support interaction (SMSI) plays an important role in tuning catalytic behavior by facilitating migration of reducible oxides from the support onto loaded metal surfaces and alloying of the guest metal with the metal component in the support. However, the conventional high-temperature redox treatment for SMSI is limited in achieving simultaneous occurrence of oxide migration and alloying mechanisms, which restricts its application in electrocatalysis. In this study, a low-temperature solvothermal-induced SMSI is established in the CeCuOx/C supported Pt system, leading to the partial encapsulation of supported Pt by CeOx and the alloying of Cu2+ in the substrate with guest Pt. This encapsulation and alloying processes significantly improve the catalysis configuration and restructure the geometric/electronic state of interfacial Pt atoms, resulting in enhanced performance for methanol oxidation reaction (MOR).

Summary: A dual-atom catalyst, Zn/Fe-NC, is synthesized through pyrolysis of PVP coated on Fe-doped ZIF-8, and it shows outstanding activity for oxygen reduction reaction (ORR) with high half-wave potential, excellent stability, and resistance to methanol. Density functional theory calculation reveals that the ORR overpotential is only 0.282 V, and the down-shifted d band center of active Fe affected by Zn alleviates the adsorption of OH* intermediates, thus promoting the overall ORR electrocatalytic activity. Moreover, zinc-air batteries with Zn/Fe-NC catalyst as oxygen cathode demonstrate remarkable power density and specific capacity for practical applications.

Summary: Inspired by the enzyme nitrogenase, researchers have explored semiconductor photocatalytic nitrogen fixation because of its similar surface catalytic processes. In this study, a facile and efficient method was developed to regulate ZnO/ZnCr2O4 photocatalysts using ZnCr-layered double hydroxide (ZnCr-LDH) as precursors. By optimizing the composition ratio of Zn/Cr in ZnCr-LDH, enhanced nitrogen photofixation performance was achieved under ambient conditions. The improved photocatalytic activity was attributed to effective carrier separation efficiency due to the abundant composite interfaces. This work demonstrates a promising strategy for synthesizing nanocomposite photocatalysts for nitrogen photofixation and other challenging photocatalytic reactions.

Summary: FeSe2-xSx microspheres were prepared by self-doping solvothermal method and gas phase selenization. S doping improved the Na adsorption and lowered the diffusion energy barrier, enhancing the electronic conductivity of FeSe2-xSx. The carbon-free nature of the microspheres resulted in a low specific surface area and high tap density, leading to a high initial columbic efficiency. Compared with pure FeSe2, FeSe2-xSx exhibited a high reversible capacity and enhanced rate performance. Additionally, FeSe2-xSx//NVP pouch cells achieved high energy and volumetric energy densities, demonstrating the potential applications of FeSe2-xSx microspheres.
