• Porous copper oxide particles were prepared by freeze-drying to serve as bulk catalysts for diesel soot combustion. Frozen particles of aqueous copper sulfate solution mixed with other metal sulfate solutions were dried in a vacuum chamber, and the dried particles were calcined into metal oxide particles. The open porosity induced by sublimation of ice crystals in the freeze-dried particles was retained during calcination and subsequent sintering. These porous Particles were directly utilized as bulk catalyst packed in a diesel soot trap. TG-DTA thermal analysis was employed to evaluate the catalyst activity in oxidation of diesel soot. In order to achieve intimate contact between catalyst dnd soot, the oxide particles were impregnated with metal chlorides, which are expected to form liquid phase during soot combustion. Among the prepared catalysts, CuO/Co_3O_4 with KC1/LiCl exhibited noticeable activity and durability, ex-hibiting an ignition temperature of 300℃ in soot combustion.
