Abstract
Porous metal materials have been widely employed as typical materials of catalysts for
cleaning exhaust gas, manufacturing a reformed gas containing hydrogen and carbon monoxide from
hydrocarbon compounds, and so on. The particle size, morphology and structure of the metal materials
are significant factors for improving catalytic activity and adsorption capacity of the materials. In this
study, Ni/Al particles were prepared by coprecipitation methods using surfactants or/and ultrasound
techniques and the influence of surfactant, ultrasonication and temperature on the structure and
morphology of the particles were investigated and their catalytic activities were evaluated via steam
reforming of ethanol.
