Abstract

Abstract: Fully utilizing solar energy for catalysis requires the integration of conversion mechanisms and therefore delicate design of catalyst structures and active species. Herein, a MOF crystal engineering method was developed to controllably synthesize a copper–ceria catalyst with well‐dispersed photoactive Cu‐[O]‐Ce species. Using the preferential oxidation of CO as a model reaction, the catalyst showed remarkably efficient and stable photoactivated catalysis, which found practical application in feed gas treatment for fuel cell gas supply. The coexistence of photochemistry and thermochemistry effects contributes to the high efficiency. Our results demonstrate a catalyst design approach with atomic or molecular precision and a combinatorial photoactivation strategy for solar energy conversion. Abstract : Die photoaktivierte Katalyse der Kohlenmonoxid‐Oxidation wurde durch die Verwendung eines Katalysators mit spezifizierten und homogen dispergierten aktiven Spezies erreicht. Der Katalysator wurde durch MOF‐Kristall‐Engineering entworfen und ermöglicht durch photothermische und photoelektrische Mechanismen die volle Nutzung der Sonnenenergie bei ausgezeichneter Stabilität.
