Abstract
The microstructure with open, interconnected macropores of 3DOM Ce(1-x)Zr(x)O(2), successfully prepared using PMMA colloidal crystal as template and cerium nitrate and zirconium oxide chloride as raw materials, facilitates the contact between soot and catalysts and results in much higher catalytic activity for diesel soot combustion than the corresponding disordered macroporous catalysts.
摘要
采用 PMMA 胶体晶体作为模板，硝酸铈和氧氯化锆作为原料，成功制备了具有开放、相互连通的大孔的 3DOMCe(1-x)Zr(x)O(2)，其微观结构有利于炭黑与催化剂的接触，使得其对柴油机炭黑燃烧的催化活性远高于相应的无序大孔催化剂。
