Interfacial Acid Sites‐Mediated ZnO‐Based Electrocatalysts for Sustainable Dual‐Pathway H2O2 Production and Rechargeable Zn‐H2O2 Electrochemical Cell

Advanced Materials, EarlyView.
In this work, a synergistic strategy introduces interfacial acid sites, oxygen vacancies, and built‐in electric field into ZnSe/ZnO heterojunction to optimize its electronic structure and electrode micro‐environment. This overcomes sluggish oxygen reduction reaction kinetics and low H2O2 selectivity, achieving record H2O2 productivity (754.4 M gcat−1 ...

Engineering CO2 Reduction Pathways via Alloy‐Support Interactions in Li‐CO2 Batteries

Advanced Materials, EarlyView.
Alloy‐support interactions in RuCu/NC induce interfacial charge redistribution and shift d‐band centers, steering CO2 reduction from Li2CO3 to metastable Li2C2O4. This pathway engineering lowers the rate‐determining barrier and suppresses carbonate formation, enabling high discharge voltage (3.23 V) in Li‐CO2 batteries with reduced overpotential (0.50 ...
