Role of Ni species in ZnO supported on Silicalite-1 for efficient propane dehydrogenation
文献摘要：
Propane dehydrogenation(PDH)is one of the most effective technologies to produce propene.Non-noble zinc-based catalysts have paid increasing attention because of low cost and nontoxic,compared with industrial Pt and Cr-based catalysts.However,they often suffer from limited catalytic activity and poor stability.Here,we introduced moderate Ni into ZnO supported Silicalite-1 zeolite to increase catalytic activity and stability simultaneously.Zn2+was the definite active site and NiZn alloy facilitated the slug-gish H recombination into H2 via reverse spillover.Furthermore,the introduction of Ni increased Lewis acid strength caused by electron transfer from ZnO to NiZn alloy,contributing to improved stability.For resulted 0.5NiZn/S-1,propene formation rate was 0.18 mol C3H6·(g Zn)-1·h-1 at 550℃,which was above 1.5 times higher than that over Zn/S-1 without Ni.Under stability test,the deactivation of 0.5NiZn/S-1 was 0.019 h-1,which was only 1/10 of that over Zn/S-1.
