Abstract

original image

Plasma preparation: Low-pressure plasma treatment of a templated Pt/BEA zeolite results in fast and total degradation of the organic template with simultaneous reduction of the Pt cations to clusters with a size of 1 nm. Operando FTIR study confirms the enhanced mechanism of reduction of Pt cations to clusters entrapped in the BEA zeolite pores.
