摘要
The development of advanced catalytic-electrodes, represents a highly valuable approach for converting CO2 into high-value chemicals. Herein, 3D printing technology was utilized to establishing a bimetallic Ni/Fe functionalized, self-supporting catalytic-electrodes (3D-CE-NiFe) for CO2 reduction reaction (CO2RR). Specifically, the photocurable ink is converted into electrode precursors through 3D printing, then carbonized and further modified with bimetallic Ni/Fe to form a series of catalytic electrode. As-obtained 3D-CE-NiFe exhibits good catalytic activity and stability in the CO2RR with the CO Faraday efficiency (FECO) of 87.8% and Faraday retention rate (10 h) of 91.1%. This study offers a good approach to preparation of customized catalyticelectrode, would also provide a promising model for the development of advanced catalytic electrodes in future.
