Visualizing Labor Division in Oxygen Electrocatalysis: Fully Exposed Ni Clusters Enabling Dual-Site Catalysis via Asymmetric Atomic Bridging.
Fully exposed metal cluster catalysts combine the atomic precision of single-atom catalysts with the multi-site reactivity of nanomaterials; however, achieving both structural stability and site-specific bifunctionality remains challenging. Herein, we report a Janus-type bifunctional catalyst comprising fully exposed a...
