Cu–Mn based mixed oxide type low-cost catalysts have been prepared in supported form using mesoporous Al2O3, TiO2 and ZrO2 supports. These supports have been prepared by

templating method using a natural biopolymer, chitosan. The synthesized catalysts have been characterized by XRD, BET-SA, SEM, O2–TPD and TG investigations. The catalytic activity

for CO as well as PM oxidation was studied, in a view of their possible applications in the control of emissions from solid fuel combustion of rural cook-stoves. The trend observed for the catalytic activity of the synthesized catalysts for CO oxidation was ZrO2 > TiO2 > Al2O3 while for PM oxidation it was observed to be TiO2 > ZrO2 > Al2O3. The

effect of CO2, SO2 and H2O on CO oxidation activity was also investigated, and despite partial

deactivation, the catalysts show good CO oxidation activity. An effective regeneration treatment was attempted by …
