Abstract

A TiO₂/NiO/Al₂O₃ hybrid with Ti³⁺ sites and -OH groups was successfully synthesized by performing a facial in situ topotactic transformation of NiAlTi-LDH. The optimized sample exhibited a high CH₄ formation rate of 41.34 μmol g^-1 h^-1 with nearly 76.8% selectivity in photocatalytic conversion of diluted CO₂.
