Synergistic tuning of CO 2 activation and *CHO adsorption enables high-rate electrocatalytic CO 2 reduction to CH 4 on a CuSn@N–C catalyst

Here, a “two-in-one” CuSn bimetallic nanoparticle-decorated nitrogen-doped carbon catalyst (CuSn@N–C) is reported, which synergistically promotes CO 2 activation and *CHO intermediate adsorption to boost the activity and selectivity of the CH 4 .
