Inside Back Cover: Gadolinium Changes the Local Electron Densities of Nickel 3d Orbitals for Efficient Electrocatalytic CO2 Reduction (Angew. Chem. Int. Ed. 18/2022)

A Ni-Gd-N ternary doped porous carbon black catalyst was developed for electrocatalytic CO2 reduction, as reported by Lang Xu and co-workers in their Research Article (e202201166). NiI active sites with high product selectivity and Ni nanoparticles with high conductivity are integrated within one catalyst. The Gd atoms not only tailor the sizes of the Ni nanoparticles but also change the local densities of the Ni 3d orbitals, thus enabling the catalyst to achieve high faradaic efficiency, large current density, and excellent stability.
