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.
通过后合成交换（PSE）方法制备的Ti取代的NH2-Uio-66（Zr/Ti）在可见光下对CO2还原和析氢均表现出增强的光催化性能。密度泛函理论（DFT）计算和电子自旋共振（ESR）结果表明，引入的Ti取代基作为促进电子转移的介质，从而提高了性能。
