Tailoring the interactions of heterostructured Ni4N/Ni3ZnC0.7 for efficient CO2 electroreduction
文献摘要：
Electrocatalytic CO2 reduction into CO has been regarded as one of the most promising strategies for sus-tainable carbon cycles at ambient conditions,but still faces challenges to achieve both high product selec-tivity and large current density.Here,we report a Ni4N/Ni3ZnC0.7 heterostructured electrocatalyst embedded in accordion-like N-doped carbon through a simple molten salt annealing strategy.The opti-mal Ni4N/Ni3ZnC0.7 electrocatalyst achieves a high CO Faraday efficiency of 92.3％and a large total current density of-15.8 mA cm-2 at-0.8 V versus reversible hydrogen electrode,together with a long-term sta-bility about 30 h.Density functional theory results reveal that the energy barrier for*COOH intermediate formation largely decreased on Ni4N/Ni3ZnC0.7 heterostructure compared with Ni4N and Ni3ZnC0.7,thus giving rise to enhanced activity and selectivity.A rechargeable Zn-CO2 battery is further assembled with Ni4N/Ni3ZnC0.7 catalyst as the cathode,which shows a maximum power density of 0.85 mW cm-2 and excellent stability.
