In situ formation of ZnO_x species for efficient propane dehydrogenation.

ABSTRACT: Propane dehydrogenation (PDH) to propene is an important alternative to oil-based cracking processes, to produce this industrially important platform chemical^1,2. The commercial PDH technologies utilizing Cr-containing (refs. ^3,4) or Pt-containing (refs. ^5-8) catalysts suffer from the toxicity of Cr(VI) compounds or the need to use ecologically harmful chlorine for catalyst regeneration⁹. Here, we introduce a method for preparation of environmentally compatible supported catalysts based on commercial ZnO. This metal oxide and a support (zeolite or common metal oxide) are used as a physical mixture or in the form of two layers with ZnO as the upstream layer. Supported ZnO_x species are in situ formed through a reaction of support OH grou
