Abstract:

Co3O4 composite metal oxide catalyst is prepared via the solvent assisted hydrothermal method using cobalt acetate as cobalt source. Its physicochemical properties are characterized by XRD, SEM, BET and H2-TPR, XPS, N2O-TPSR and O2-N2O-TPSR. The activity of the catalyst in catalytic decomposition of N2O is evaluated in a fixed-bed micro-reactor and the effects of crystallization temperature on its activity in catalytic decomposition of N2O are investigated. Evaluation results show that Co3O4 catalysts prepared via solvent assisted hydrothermal method have a spinel structure and the crystallization temperature does affect catalysts' morphology, redox performance and activity in catalytic decomposition of N2O. The result by N2O-TPSR and O2-N2O-TPSR shows that the oxygen adsorbed on the catalyst surface plays an important role in the catalytic decomposition of N2O. The redox performance of Co3O4 catalyst prepared at a crystallization temperature of 160℃ is good, over which the catalytic decomposition of N2O can be performed under a low temperature. The T10 and T95 are 266℃ and 410℃, respectively under the conditions that reaction gas consists (volume fraction) 0.68% of N2O, 0.88% of O2 and Ar as equilibrium gas with a flow rate of 80 mL•min-1. © 2019, China National Chemical Information Center.
