Integrating Cooperative Dual Active Sites Onto a Plasmonic Photocatalyst for Synergistic Promotion of the Reduction and Oxidation Half‐Reactions in Ammonia Synthesis

open access: yesAdvanced Science, EarlyView.
An efficient N2 fixation photocatalyst, Ru‐WO3−x/CoOx, is prepared by integrating respective reduction and oxidation sites onto a plasmonic semiconductor. Owing to optimized reaction kinetics and promoted charge carrier separation by the synergistic effect between the two types of active sites, the involved reduction and oxidation half‐reactions are ...

Electrocatalytic Nitrate Reduction to Hydroxylamine: Breaking the Activity‐Selectivity Trade‐Off by Designer Bifunctional Metal‐Organic Frameworks

open access: yesAngewandte Chemie, EarlyView.
A bifunctional metal‐organic framework (MOF) catalyst with dual active sites is developed for enabling NH2OH electrosynthesis via NitRR with both high selectivity and activity. ABSTRACT Electrocatalytic nitrate reduction reaction (NitRR) offers a promising route for hydroxylamine (NH2OH) synthesis under ambient conditions.

Boosting Bulk‐to‐Surface Electron Transfer in CeO2 via Oxygen Vacancy Channels for Ultrafast NO2 Sensing

open access: yesAdvanced Science, EarlyView.
The formation of electron transport channels overcomes the sluggish electron migration caused by polaron localization, significantly enhancing surface electron concentration and reaction activity, thereby promoting the adsorption and activation of O2 and NO2.
