Easy synthesis of three-dimensionally ordered macroporous La1−xKxCoO3 catalysts and their high activities for the catalytic combustion of soot
TL;DR: In this paper, a 3D-ordered macroporous (3DOM) La1−xKxCoO3 (x = 0-0.3) perovskite-type oxide catalysts with large pore sizes and interconnected macroporic frameworks were successfully synthesized by a novel method of carboxy-modified colloidal crystal templates (CMCCT).
Journal ArticleDOI
Three-dimensionally ordered macroporous LaCoxFe1−xO3 perovskite-type complex oxide catalysts for diesel soot combustion
TL;DR: In this paper, a series of 3D-ordered macroporous (3DOM) LaCoxFe1−xO3 (x = 0-0.5) perovskite-type catalysts were synthesized by using colloid crystal template (CCT) method with the polymethyl methacrylate (PMMA) microspheres as template.

TL;DR: 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, results in much higher catalytic activity for diesel soot combustion than the corresponding disordered macroporous catalysts.
Journal ArticleDOI

TL;DR: In this article, three-dimensional ordered macroporous (3DOM) praseodymium (Pr)-modified Ce-Zr solid solutions were successfully prepared by colloidal crystal templating method.
Journal ArticleDOI
The synthesis and catalytic performances of three-dimensionally ordered macroporous perovskite-type LaMn1−xFexO3 complex oxide catalysts with different pore diameters for diesel soot combustion
TL;DR: In this paper, polymethyl methacrylate (PMMA) microspheres with diameters of 300-800nm were synthesized by a modified emulsifier-free emulsion polymerization technique with water-oil biphase double initiators.
