Abstract

Abstract : Introduction of Ti as a mediator in Ti substituted NH2 -Uio-66(Zr) is an effective way to improve its photocatalytic performance. Abstract : Ti-substituted NH2 -Uio-66(Zr/Ti) prepared by using a post-synthetic exchange (PSE) method showed enhanced photocatalytic performance for both CO2 reduction and hydrogen evolution under visible light. Density functional theory (DFT) calculations and electron spin resonance (ESR) results reveal that the introduced Ti substituent acts as a mediator to facilitate electron transfer, which results in enhanced performance.
