Selective photoreduction of diluted CO 2 to CH 4 via topotactic transformation of mixed metal oxides derived from NiAlTi-LDH

Topotactic strategy was proposed for fabricating TiO 2 /NiO/Al 2 O 3 heterojunction. Benefiting from the presence of Ti 3+ sites and –OH groups, Ti 3+ –OH/NAM 300 demonstrated optimal activity and selectivity for the conversion of diluted CO 2 to CH 4 .
