Copper Single Atoms on a Photothermal Heterostructure for Dual‐Field‐Driven Nitrate‐to‐Ammonia Conversion
Electrocatalytic reactions involving multiple electrons and protons, such as nitrate reduction to ammonia, are constrained by sluggish interfacial charge‐transfer and inefficient mass transport. Here, we propose a dual‐field‐driven strategy that integrates the local thermal field and the built‐in electric field wit...
