Dynamic surface restructuring of nanoporous Cu2−xSe for efficient CO2 electroreduction into methanol

The nanoporous Cu2−xSe with Cu(Se-5%) surface catalysts were prepared through in situ dynamic restructuring strategy during the electrochemical process, which achieves highly selective electrochemical CO2 reduction to methanol. In situ and quasi-operando spectroscopic results provide a deep insight into the catalytic active centres of reconstructed heterogeneous catalysts for CO2 electroreduction.
