Engineering valence-mismatched Ti into Fe-based metal-organic-frameworks for enhanced photocatalytic CO reduction
A series of low-dose high-valence Ti 4+ doped MIL-53-NH 2 (Fe) photocatalysts were synthesized for visible-light-driven CO 2 reduction. The highest CO 2 -to-CO conversion rate of Ti 4+ doped MIL-53-NH 2 (Fe) was 7.24 mmol g −1 h −1 and the highest CO selectivity was 94% in acetonitrile solvent using...
