Photocatalysis of metal clusters in cages: effective photoactivation of the water gas shift reaction catalysed on NaY zeolite-entrapped Pt12 and Pt9 carbonyl clusters

Abstract

Pt carbonyl clusters [Pt₃(CO)₆]_n,^2–(n= 3,4) in NaY zeolite pores are catalytically active for the water gas shift reaction (CO + H₂O) at low temperatures, and exhibited effective photocatalysis for this reaction with a marked enhancement (ca. 38 times higher at 293 K) under illumination from a Xe lamp compared with the dark reaction.
