- Abstract
The design of efficient photocatalysts is essential for photocatalytic CO
2 reduction. With the goal of enhancing efficiency to produce C2+ products, in this study, we synthesized photocatalysts based on an Fe-MOF composited with facet-engineered palladium nanoparticles (Pd NPs). The synthesis involves in situ reduction of palladium on the surface of the Fe-MOF, namely MIL-100(Fe). When assessing the photocatalytic performance, the synthesized catalyst Pd(111)/MIL-100 exhibits a photoelectron utilization efficiency of 21.4% for converting CO2 into C2+ products, surpassing those in the majority of previously reported studies. The results show that MIL-100(Fe) loaded with Pd NPs that exposed the Pd(111) facet is superior for C2+ product selectivity compared with Pd(100)/MIL-100. Density functional theory (DFT) calculations suggest that the difference between Pd(111)/MIL-100 and Pd(100)/MIL-100 may be attributed to the energy barriers required for transition states during the reaction. This study offers an approach for designing photocatalytic catalysts for the CO2 reduction reaction (CO2 RR) and generating C2+ products. [ABSTRACT FROM AUTHOR]- Published
