Defect engineering of NiCo-layered double hydroxide hollow nanocages for highly selective photoreduction of CO₂ to CH₄ with suppressing H₂ evolution

Abstract

We found that abundant defects could be created in the HC-NiCo-LDH by constructing a hollow nanocage morphology. The HC-NiCo-LDH showed excellent CO₂ photoreduction performance that increasing the CH₄ selectivity while suppressing the H₂ evolution.
