Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction
Advanced Functional Materials, EarlyView.Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...
