单原子Ni、N共掺杂碳材料基催化剂(Ni-N-C)电催化CO2制CO,因其在较大的电流密度和较大的过电势下仍具有超高的CO选择性,引起了广泛关注.本文综述了Ni-N-C电催化CO2制CO研究进展,包括氮掺杂碳材料基催化剂和Ni-N-C电催化CO2制CO.总结了氮掺杂碳材料基催化剂中不同形态N的催化活性,目前为止,N在该类催化剂电化学还原CO2中的确切作用没有达成共识.此外,还总结了Ni-N-C的催化性能、催化机理及催化性能改性方法,探讨了与Ni配位的N原子和缺陷位对催化活性的影响规律,分析了各类碳载体的优缺点.Ni-N-C电化学还原CO2制CO研究已取得一定的进展,如电流密度可达工业级要求,但是其实现大规模工业化应用还需解决一些关键问题,如开发高活性和高稳定性Ni-N-C的定向制备技术;研发制备简易温和、成本低廉、具有抗腐蚀性、耐高温的先进碳载体材料.
Recent advances in electroreduction of CO2 to CO using single atom Ni,N co-doped carbon-material based catalysts
Study of single-atom Ni and N co-doped carbon-material based catalysts(Ni-N-C)for CO2 electrochemical reduction(CO2ER)to CO began in the past decade.It has received a lot of attentions because it possessed ultra-high CO selectivity even under high current density and high overpotential.This article reviewed recent advances in Ni-N-C for CO2ER to CO,including nitrogen doped carbon-material based catalysts and Ni-N-C for CO2ER to CO.The catalytic activities of different forms of N in carbon-material based catalysts were summarized,and so far,the exact role of N in carbon-material based catalysts for CO2ER was controversial.Moreover,the catalytic performance,catalytic mechanism and catalytic performance modification for Ni-N-C were also summarized.The effects of N atoms and defect sites coordinated with Ni on catalytic activity,and the advantages and disadvantages of various carbon-carriers were analyzed.Although research on CO2ER to CO using Ni-N-C has made certain progress,such as the current density reaching industrial grade requirements,some key issues still needed to be solved to achieve its large-scale industrial applications,such as developing directional preparation technologies for high activity and high stability Ni-N-C and developing advanced carbon-material carriers,which were simple and mild preparation,low cost,corrosion-resistant high-temperature resistant.
