摘要

本研究通过电化学活化构建了具有Se空位的NiSe2@CoSe2异质结构，增加了活性位点的密度，对材料的电子结构进行了精细调整，优化了Co的三维轨道自旋态，实现了优异的乙醇氧化（1.33 V @ j10），将水分解的能耗降低了60%，将zn -乙醇-空气电池的能耗降低了20%。

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 spin states, and enabled superior ethanol oxidation (1.33 V @ j10), reducing energy consumption by 60% in water splitting and 20% in Zn-ethanol-air batteries.
