Abstract
Abstract Photocatalytic reduction of CO 2 has drawn much attention as a promising way that can effectively alleviate the issue of global warming and energy crisis. In this work, we fabricated a series of CdS/NH 2 ‐UiO‐66 composites with varied CdS amounts and tested their capacity for photocatalytic reduction of CO 2 . The reactions were performed in a solvent‐free system and displayed excellent selectivity for CO production without liquid phase products. When the content of CdS in the composite is up to 40 %, the hybrid catalyst produces 105.41 μmol/g within 6 h, exhibiting remarkable photocatalytic performance, which is much higher than that catalyzed by mechanically mixed CdS and NH 2 ‐UiO‐66. The brilliant catalytic performance of the composite catalyst is attributed to the formation of heterostructure between the well‐dispersed CdS and NH 2 ‐UiO‐66, which promotes the enhancement of electron transfer during photocatalysis.
