Photocatalytic Methanol Dehydrogenation Promoted Synergistically by Atomically Dispersed Pd and Clustered Pd

Journal of the American Chemical Society, Journal Year: 2024, Volume and Issue: 146(35), P. 24440 - 24449

Published: Aug. 20, 2024

Supported metal in the form of single atoms, clusters, and particles can individually or jointly affect activity supported heterogeneous catalysts. While individual contribution to overall photocatalysts has been identified, joint mixed species is overlooked because their different photoelectric properties. Here, atomically dispersed Pd (Pd1) clusters are loaded onto CdS, serving as oxidation reduction sites for methanol dehydrogenation. The Pd1 substitutes Cd2+, forming hole-trapping states assisting dispersion photodeposited clusters. Therefore, dehydrogenation on CdS with exhibits highest turnover frequency 1.14 s–1 based content affords H2 HCHO a similar apparent quantum yield 87 ± 1% at 452 nm under optimized reaction conditions. This work highlights synergistic catalysis improved photocatalytic activity.
