Metal-based catalysts for the non-oxidative dehydrogenation of light alkanes to light olefins

Abstract

Catalytic non-oxidative dehydrogenation of light alkanes is one of the most promising routes for the production of value-added olefins because of high selectivity to the target alkenes and increased supply of natural and shale gas. In this review, we emphasize the recent advances in the development of metal-based catalysts for the direct dehydrogenation of light alkanes to olefins. Metal-based catalysts including Pt-, Pd-, Rh- and Ni-based catalysts, particularly Pt-based bimetallic catalysts, are summarized and exemplified. A detailed discussion of the structure–performance correlations of these catalysts is presented. We systematically discussed the geometric and electronic effects of the promoters on these metal-based catalysts. Moreover, we highlighted recent advanced strategies for improving the dehydrogenation performance and the stability of metal-based catalysts. In light of the existing contributions, a perspective was provided to evaluate some of the potential avenues into future research. We hope that this review will inspire the rational design of metal-based catalysts to realize efficient direct dehydrogenation of light alkanes for olefins production.
