Tailoring Electronic Structures of Ni@N-doped Carbon Hollow Urchins for Dual-Functional Zn-CO2 Batteries and Industrial CO2 Electroreduction

A catalyst with a hollow urchin-like sphere structure and porous surface was synthesized using Ni-MOF precursors (Ni@N-HCS). This catalyst features nickel nanoparticles encapsulated by nitrogen-doped carbon shells and exhibits excellent...
