固体氧化物电解池（SOECs）具有较高的电解速率和能量转化效率，可以在阴极侧实现CO2的高效转化。阳极侧烷烃的引入可以在电解池两侧同时产生高附加价值的化学产品。本项目基于固体氧化物电解池拟通过不同组分的纳米颗粒原位构筑、卤族元素引入等手段开发高催化活性的钙钛矿电极材料，创新性的探究其对CO2电解和CnH2n+2电化学重整的影响规律，构建材料的组成-形貌-结构-性能之间的内在关联，阐明CO2电解和CnH2n+2电化学重整之间的协同作用机制，实现SOECs两侧目标产品的可控制备，为促进SOECs商业化奠定扎实的实际应用基础和理论基础。

CO2 can be converted to useful chemicals through solid oxide electrolysis cells due to its high efficiency. Moreover, the chemicals such as CO，H2, C2H4, can be produced in both anode and cathode when the alkane is introduced into SOECs anode. The proposal develops electrode materials with high catalytic activity by in-situ growth of nano particles and halogen doping methods. The CO2 electrolysis and electrochemical reforming of CnH2n+2 are investigated. The properties of electrode materials such as conductivity, stability and catalytic activity will be thoroughly studied and correlated with the composition, morphology, structure. The synergistic mechanism between CO2 electrolysis and electrochemical reforming of CnH2n+2 will be explored. It is expectable that the target chemicals can be produced in both SOECs anode and cathode.
