Crystalline-Amorphous Interfaces Enriched CuS-SnS Composite Catalyst Boosts Electrochemical CO2 Reduction over a Wide pH Window

Abstract

A copper sulfide-tin sulfide composite catalyst featuring crystalline-amorphous hybrid interfaces is developed for highly efficient electrochemical CO2 reduction to formate across a broad pH range (1.81-13.28), achieving a highest Faradaic efficiency of 93.9%.
