Restructuring surface lattice hydroxyls on NiSn(OH)6 towards enhanced photoreduction of CO2 to CO

Abstract

Here, a kinetically boosted solar-driven CO₂ reduction was enabled by restructuring surface lattice hydroxyls with the doping of Co²⁺ into NiSn(OH)₆, activating Ni–OH as donors to readily release protons and generate oxygen vacancies due to the lowered reaction barrier, coupled with improving migration of electron–hole pairs and adsorption of CO₂.
