Construction of N-doped carbon frames anchored with Co single atoms and Co nanoparticles as robust electrocatalyst for hydrogen evolution in the entire pH range
文献摘要:
The development of low-cost,efficient,and high atomic economy electrocatalysts for hydrogen evolution reaction(HER)in the entire pH range for sustainable hydrogen production is of great importance but still challenging.Herein,we synthesize a highly dispersed N-doped carbon frames(NCFs)anchored with Co single atoms(SAs)and Co nanoparticles(NPs)catalyst by a doping-adsorption-pyrolysis strategy for elec-trocatalytic hydrogen evolution.The Co SAs-Co NPs/NCFs catalyst exhibits an excellent HER activity with small overpotential,low Tafel slope,high turnover frequency as well as remarkable stability.It also exhi-bits a superior HER performance in the entire pH range.Combining with experimental and theoretical calculation,we find that Co SAs with Co-N3 coordination structure and Co NPs have a strong interaction for promoting synergistic HER electrocatalytic process.The H2O molecule is easily activated and dissoci-ated on Co NPs,while the generated H* is easily adsorbed on Co SAs for HER,which makes the Co SAs-Co NPs/NCFs catalyst exhibit more suitable H adsorption strength and more conducive to the activation and dissociation of H2O molecules.This work not only proposes a novel idea for constructing coupling catalyst with atomic-level precision,but also provides strong reference for the development of high-efficiency HER electrocatalysts for practical application.
