Modulation of Se Vacancy on NiSe2@CoSe2 Heterostructures to Optimize Ethanol Electrooxidation Activity for Efficient Hybrid Water Splitting and Zinc-Ethanol-Air Batteries

This work constructs a NiSe2@CoSe2 heterostructure with Se vacancies via electrochemical activation, increased the density of active sites, fine-tuned the electronic structure of the material and optimized Co 3d orbital...
