Abstract Reducing carbon dioxide （CO 2 ）to high‐value products using green renewable energy is a promising approach for addressing and greenhouse effect issues. Consequently, electrocatalytic CO reduction reaction (CO RR) technology has become current research hotspot. Since the discovery of high activity selectivity copper in RR, atomically dispersed Cu catalysts have garnered widespread attention due to their efficient atom utilization, unique electronic structure, outstanding catalytic performance. However, great challenge remains providing rational catalyst design principles achieve regulation product distribution. A clear understanding materials an in‐depth interpretation mechanism as well elucidation strategy progress toward different are keys building solving above problem. Therefore, this review starts with introduction advanced characterization techniques reveal structure mechanisms. Then, various optimization strategies applications producing targeted summarized discussed. Finally, perspectives on RR field future development offered.

Abstract Although numerous enzyme‐mimicking nanomaterials have been developed to regulate the highly reactive oxygen species (ROS)‐rich microenvironment of diabetic wounds for improving its healing, poor broad‐spectrum ROS‐scavenging capacity and biological toxicity resulting from side reactions still require improvement. To tackle these challenges, a polyphenol‐mediated copper‐bismuth bimetallic artificial metalloproteinases, CuBi‐TA@BSA, based on protein‐scaffold design strategy, is conceptually engineered. The Bi polyphenols can cooperatively enhance loading Cu ions their coordination within BSA scaffold. CuBi‐TA@BSA exhibits remarkable scavenging activity against various ROS via effectively donating electrons, as well reaction pathway specificity catalytic H 2 O decomposition without POD‐like activity. Moreover, in vitro vivo studies further confirm that protect cells oxidative damage, inhibit onset progression inflammation, promote wound healing. This work presents simple strategy biocatalysts scavenge accelerate wound‐healing process, also provides designing metalloproteinases antioxidative therapy.
