Morphology-controlled porous carbons with dispersed Cu catalysts for efficient electrocatalytic nitrate reduction to ammonia

Abstract

A strategy combining solvent-induced self-assembly and controlled pyrolysis constructs porous carbon nanostructures with distinct morphologies and atomically dispersed Cu sites. The optimized catalyst exhibits excellent NO₃RR performance, delivering 94.7% faradaic efficiency and 4.05 mol g⁻¹ h⁻¹ NH₃ yield.
