Characterization of Super-Solubilization Nanometer Self-Assembly Bulk Ni-Al2 O3 Catalysts and Self-Assembly Mechanism
摘要
Abstract
In the way of super-solubilization self-assembled,bulk catalyst Ni-Al2 O3 is prepared with the carrier Al2 O3 and nickel.Ni-Al2 O3 catalyst was characterized by SEM and TG-DTG,and nano self-assemlbe mechanisms were also discussed. The SEM results show that super-solubilization self-assembled method can construct bulk catalyst Ni-Al2 O3 which has a uniform particle,narrow distribution particle diameter,large specific surface area and pore volume.And after reduction, primary particle and secondary particle are also nanoparticle,porous channel between particles is 50~200 nm which is formed in the process of primary and secondary nanoscale self-assembly.TG-DTG results with air and nitrogen atmosphere show that the temperture in the nitrogen atmosphere lags behind that in the air atmosphere.This is because that hydrocarbons templates burn in advance and loss weight in the presence of oxygen.Actual value of weight loss rate is much higher than theoretical value on account of that templates was not made full used.关键词
