      abstract = {In this research, a well-defined CeO2 (rod, cube, and polyhedron) were elaborately constructed as the nanocatalysts with predominantly exposed facets of {110}, {100}, and {111}, respectively.TheCeO2nanocube catalyst supported with metals ion (Mn and Pt) was successfully synthesized by gas bubbling-assisted membrane reduction (GBMR) method. Activity test results show that all the synthesized catalysts are good, but PtMn-CeO2 catalyst has the best soot burning activity (T50 = 367 oC). The PtMn-CeO2 catalyst has the best catalytic activity. The synergy between Pt and Co can effectively increase the number of surface oxygen vacancies and promote surface active oxygen generation. Thereby accelerating the adsorption and activation of reactant molecules (O2 and NO) and increasing the mobility of lattice oxygen.Through various characterizations (SEM, BET and H2-TPR), the effect of CeO2 catalyst on crystal plane was systematically studied. The study showed that the catalytic activity of CeO2NOx removal catalyst which mainly exposed {110} crystal plane and its excellent low-temperature oxidation-reduction performance was found to be more promising in terms of totalNOx particles removal.The research discovered that using gas film assisted reduction method; platinum and manganese nanoparticles were uniformly dispersed and loaded onto cerium dioxide carriers. Through SEM characterization, it was evident that Pt/Mn CeO2 and other catalysts were successfully prepared and the morphology of the loaded catalysts remained intact. Cerium dioxide demonstrated some catalytic activities which were further enhanced by the addition of Pt and Mn nanoparticles. Notably, when Pt and Mn nanoparticles were loaded simultaneously, the T50 of Pt/Mn-CeO2 decreased to 367? under loose contact conditions.},
