由不同镍盐前体制备高分散Ni／SBA-15催化剂：活化氛围的影响
Highly dispersed Ni/SBA-15 catalysts prepared with different nickel salts as nickel precursors:Effects of activation atmospheres
摘要
Abstract
With nickel nitrate and nickel acetate as nickel precursors, a series of Ni/SBA-15 catalysts were prepared by using the impregnation methdo a nd activating in air or hydrogen atmosphere.The Ni/SBA-15 catalysts were characterized with XRD, H2-TPD, N2 physisorption and online mass spectroscopy. Their catalytic properties were evaluated with hydrogenation of naphthalene as a model reaction.It was shown that activation in hydrogen greatly increased the Ni dispersion and catalytic activity of Ni/SBA-15 prepared with nickel nitrate, while activation in air significantly improved the sample prepared with nickel acetate.In terms of the thermal decomposition prdo ucts of the catalyst precursors activated in different atmospheres, the affecting mechanism of the activation atmosphere no the Ni/SBA-15 catla ysts prepared with different nickel precursors was proposed.关键词
