ИСТИНА

In the present work CeO2-ZrO2 mixed oxide was synthesized with the use of waste biomass (pine sawdust). Samples were characterized by methods BET, SEM and catalytic activity was measured in oxidation of model soot (carbon black (CB): N330n Degussa). Using sawdust as matrix for preparing the catalysts leads to biomorphic structure of the final mixed oxides. Obtained oxides exhibit besides high surface area also heightened shortness, which favours improving contact between soot and catalyst and in this way decreases the temperature of soot combustion.
