Solar Energy Catalysis

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(29)

Опубликована: Апрель 26, 2022

When it comes to using solar energy promote catalytic reactions, photocatalysis technology is the first choice. However, sunlight can not only be directly converted into chemical through a photocatalytic process, also different energy-transfer pathways. Using as source, reactions proceed independently, and coupled with other technologies enhance overall efficiency. Therefore, sunlight-driven are diverse, need given specific definition. We propose timely perspective for driven by give them definition, namely "solar catalysis". The concept of types catalysis, such photocatalysis, photothermal cell powered electrocatalysis, pyroelectric highlighted. Finally, their limitations future research directions discussed.

Subsurface oxygen defects electronically interacting with active sites on In2O3 for enhanced photothermocatalytic CO2 reduction

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Июнь 9, 2022

Abstract Oxygen defects play an important role in many catalytic reactions. Increasing surface oxygen can be done through reduction treatment. However, excessive blocks electron channels and deactivates the catalyst due to electron-trapped effects by subsurface defects. How effectively extract electrons from which cannot directly interact with reactants is challenging remains elusive. Here, we report a metallic In-embedded In 2 O 3 nanoflake over turnover frequency of CO into increases factor 866 (7615 h −1 ) 376 (2990 at same light intensity reaction temperature, respectively, compared . Under electron-delocalization effect O-In-(O)V o -In-In structural units interface, are extracted gather active sites. This improves electronic coupling stabilizes intermediate.

Photo-thermo semi-hydrogenation of acetylene on Pd1/TiO2 single-atom catalyst

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Май 12, 2022

Abstract Semi-hydrogenation of acetylene in excess ethylene is a key industrial process for purification. Supported Pd catalysts have attracted most attention due to their superior intrinsic activity but often suffer from low selectivity. single-atom (SACs) are promising significantly improve the selectivity, needs be improved and feasible preparation SACs remains grand challenge. Here, we report simple strategy construct 1 /TiO 2 by selectively encapsulating co-existed small amount nanoclusters/nanoparticles based on different strong metal-support interaction (SMSI) occurrence conditions. In addition, photo-thermo catalysis has been applied this where much-improved catalytic was obtained. Detailed characterization combined with DFT calculation suggests that photo-induced electrons transferred TiO adjacent atoms facilitate activation acetylene. This work offers an opportunity develop highly stable efficient semi-hydrogenation process.
