We report single-atom Cu catalysts dispersed on nitrogen-doped carbon by a nitrogen-coordination strategy. The presence of nitrogen enabled good dispersion and attachment atomic species the frameworks with Cu–Nx configurations. doping concentrations configurations were well-tuned pyrolysis temperature. At high concentration 4.9%mol, distance between neighboring was close enough to enable C–C coupling produce C2H4. In contrast, at lower than 2.4%mol, large so that electrocatalyst favored...
Monodispersed single metal atoms have been demonstrated with unique potentials for electroreduction of CO2 or CO, while the capability producing multicarbon (C2+) products is still limited. In this work, we developed a dual atomic catalyst uniform distributions two adjacent Cu–Cu Cu–Ni anchored on nitrogen-doped carbon frameworks, featuring distinctive catalytic sites CO electroreduction.

The electrochemical CO2 conversion to formate is a promising approach for reducing level and obtaining value-added chemicals, but its partial current density still insufficient meet the industrial demands. Herein, we developed surface-lithium-doped tin (s-SnLi) catalyst by controlled lithiation. Density functional theory calculations indicated that Li dopants introduced electron localization lattice strains on Sn surface, thus enhancing both activity selectivity of electroreduction formate....
