Abstract:
The strategic design of heterostructured interfaces is a powerful avenue for optimizing electrocatalytic performance, yet leveraging crystalline-amorphous interactions for the CO2 reduction reaction (CO2RR) remains underexplored. Herein, an Ag/La(OH)3 crystalline-amorphous heterostructure was constructed by a facile synthesis. This unique configuration induces strong electronic coupling, optimizing intermediate adsorption. The optimized catalyst achieves exceptional CO selectivity with a 97.6% faradaic efficiency at -0.78 V vs. RHE. Furthermore, it enables a Zn-CO2 battery with a 16.71 mW cm-2 peak power density.
