摘要：

Propane metathesis reactions over group 2-5 metal hydrides were investigated. Among the tested metal hydrides, TiH2 exhibited the highest butane yield as a metathesis reaction product. Fully-hydrogenated TiH2 is much more active than dehydrogenated TiH and Ti metal. Surface low-valent Ti species over TiH2 is involved in the propane metathesis reaction. This study is the first example of carbon-carbon bond cleavage and catalytic formation over bulk metal hydrides. Propane metathesis reactions over group 2-5 metal hydrides were investigated where TiH2 exhibited the highest butane formation amount. This study is the first example of carbon-carbon bond cleavage and formation over bulk metal hydrides.
