Regulating the hydrophobic microenvironment of SnS2 to facilitate the interfacial CO2/H2O ratio towards pH-universal electrocatalytic CO2 reduction

A hydrophobic microenvironment near SnS 2 was constructed using polyvinylidene fluoride modification, which could increase the CO 2 concentration around SnS 2 surface. This strategy could enhance catalytic performance of SnS 2 across a wide pH range.
