Size Structure - Catalytic Performance Correlation of Supported Ni/MCF-17 Catalysts for COx-free Hydrogen Production

Abstract

Supported Ni/MCF-17 catalysts with nickel nanocrystal size in the range of 1.5-8.0 nm were synthesized and employed for COx-free hydrogen production for fuel cells via ammonia decomposition reaction. Characterized by a variety of techniques, the results show that nickel particles are in a highly dispersed state with uniform particle size for each catalyst. Furthermore, the influence of particle size on the catalytic performance has also been investigated. It was later revealed that Ni nanoparticles with different particle sizes have significant difference in catalyzing COx-free hydrogen production reaction. Moreover, the catalyst with Ni nanoparticles size around 3.0 nm exhibited the highest catalytic activity in each reaction temperature, which can be explained by the presence of high B5 active sites of Ni-based catalysts surface.
