【Abstract】 BET and SEM techniques were used to study the influence of pore expanding agents(urotropine and urea) on properties of the carriers for automotive catalysts. It was shown that addition of an appropriate amount of pore expanding agents (about 30%) can effectively increase surface area of the carriers and improve its properties.更多还原
