Three dimensionally ordered macroporous Ce(1-x)Zr(x)O(2) solid solutions for diesel soot combustion.
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.
