Effect of TiO_2 support on immobilization of cobalt porphyrin for electrochemical CO_2 reduction

【摘要】:Electrochemical reduction of CO_2 is a promising strategy to manage the global carbon balance by transforming CO_2 into chemicals. The efficiency of CO_2 electroreduction is largely dependent on the design of hybrid electrode where both support and catalyst govern the performance of the electrolyzer. In this work,TiO_2 calcined at different temperatures, was used as a support for immobilization of cobalt tetraphenyl porphyrin(CoTPP) and its effect on CO_2 reduction was studied. It is demonstrated that the crystalline phase of TiO_2 and doping of TiO_2 apparently affecting CO_2 electroreduction. It is found that anatase phase exhibits higher activity and selectivity compared to rutile due to the enhanced conductivity which in turn enables faster electron transfer between the support and CoTPP. As for dopants, the carbon doping in anatase TiO_2 is proven to further enhance its conductivity, consequently resulting in the enhanced performance. This study implies that the rational design of supports is important for the performance of the hybrid electrode towards electrochemical CO_2 reduction.
