摘要

Abstract

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. Zn

was the definite active site and NiZn alloy facilitated the sluggish H recombination into H

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 C

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

which was only 1/10 of that over Zn/S-1.
