A combination of 10 wt% copper oxide, manganese oxide, and nickel oxide was added to the Ce0.75Zr0.25O2 support by impregnation method and calcined in the air with a flow rate of 2 ml s−1 at 400 °C for 4 h. All catalysts were characterized using Hydrogen Temperature Programmed Reduction (H2-TPR), X-ray Diffraction (XRD), and Brunauer-Emmet-Teller (BET) isotherm methods to find the interaction between metals, the crystallinity of the catalyst, surface area and pore volume of the catalyst, respectively. The 3.3% CuO-3.3% MnO2-3.3% NiO/Ce0.75Zr0.25O2 catalyst showed higher catalytic activity for benzene oxidation with benzene conversion of 90% at 250 °C and weight hourly space velocity (72,000 mL g−1 h−1) when compared to one metal oxide only. This finding presents a high activity and low-cost catalysts for removing a very lean concentration of benzene containing in the industrial flue gas at low temperatures.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Benzene oxidation,Brunauer emmet tellers,Coprecipitation method,Hydrogen temperature programmed reduction,Impregnation methods,Industrial flue gas,Low cost catalysts,Weight hourly space velocity[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Catalyst,Ceria-zirconia,Combustion,Metal oxide,VOC[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors would like to acknowledge the Ministry of Research, Technology, and Higher Education of Indonesia, under the research scheme of PUSN with the contract number: 127/SP2H/PTNBH/DRPM/2018 for financial support in this research.
