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

Advanced 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 ...

Enhanced Photocatalytic CO2 Reduction Performance by External Electric Field‐Driven Charge Separation on Interdigitated Micro‐Spacing Structure

Advanced Science, EarlyView.
An external electric field‐enhanced photocatalytic system is developed using interdigitated electrodes with 100 µm spacing to overcome the liquid‐phase limitations of traditional PEC. The induced high‐intensity electric field effectively drives the directional migration of charge carriers under low voltage. This strategy significantly suppresses charge

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis

Advanced Science, EarlyView.
Additive and partially dominant effects, namely at mid‐parent levels or values between mid‐parent and parental levels, respectively, are the predominant inheritance patterns of heterosis‐associated molecules. These two genetic effects contribute to heterosis of agronomic traits in both rice and maize, as well as biomass heterosis in Arabidopsis ...

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

Advanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

Atomic Precision CoCu Heterodimers with Pseudo‐D3h Symmetry Enable Tandem Nitrate Reduction

Advanced Science, EarlyView.
The Co─Cu heterodimer anchored on nitrogen‐doped graphene oxide substrate facilitates electrochemical nitrate reduction in alkaline medium. Co site promotes water dissociation to supply a proton, while Cu sites enhance nitrate adsorption and activation.
