Photothermal Synergistic Catalytic Ethanol Reforming with CO2 over Ni/TiO2
Ethanol reforming with CO2 to produce syngas is one of the feasible strategies for greenhouse gas CO2 emission reduction and sustainable utilization of carbon resources,which is favorable to achieving the goal of carbon peak and carbon neutrality.In this work,the photothermal ethanol dry reforming reaction was studied in detail over supported Ni/TiO2 catalyst.The physicochemical features of the catalyst were investigated by a serious of characterization techniques,including SEM,TEM,BET,XRD,UV-VIS DRS,H2-TPR,and CO2-TPD.The results indicated that the Ni/TiO2 catalyst possessed sufficient oxygen vacancies and a narrow bandwidth,thereby expanding its photo response range.The photothermal synergistic effect could reduce the activation energy of the reaction,enhance the reaction rates,inhibit the generation of methane and acetone byproducts.The findings might guide the design of highly efficient photothermal heterogeneous catalysts and the value-added utilization of CO2.
