Abstract | The development of high-efficiency catalysts for carbon dioxide reduction reaction (CO2RR) and oxygen evolution reactions (OER) is an important strategy to solve the current energy crisis. In this paper, solid-phase exfoliation and electrostatic self-assembly strategies are developed to couple ultrathin NiFe-layered-double-hydroxide nanosheets and carbon nanotubes (CNT@NiFe-LDH NS) as an OER catalyst. Then, NiFe nanoparticles anchored on the N-doped CNT (CNT-N-NiFe) for electrocatalyst of CO2RR is synthesized via pyrolysis of a mixture of CNT@NiFe-LDH NS and melamine in a nitrogen atmosphere at 750 °C, utilizing the ultrathin NiFe-LDH NS as a metal source and CNT as the framework. CNT@NiFe-LDH NS nanohybrid exhibits a better catalytic activity for OER (with an overpotential of 270 mV at the current density of 20 mA cm–2 and remarkably stable durability) than Bulk NiFe-LDH in 1 m KOH. Moreover, the CNT-N-NiFe catalyst exhibits a Faradaic efficiency of ≈82.6% for the reduction of CO2 to CO at −0.7 V (vs reversible hydrogen electrode) with a current density of CO 10.2 mA cm–2. The method of preparing CO2RR catalysts provides a new idea of the preparation of bimetallic CO2RR electrocatalysts. |
