Abstract Electrochemical reduction of CO 2 into liquid fuels is a promising approach to achieve carbon‐neutral energy cycle. However, conventional electrocatalysts usually suffer from low efficiency and poor selectivity stability. A 3D hierarchical structure composed mesoporous SnO nanosheets on carbon cloth proposed efficiently selectively electroreduce formate in aqueous media. The electrode fabricated by facile combination hydrothermal reaction calcination. It exhibits an unprecedented...
