Strong Electronic Interaction in Dual‐Cation‐Incorporated NiSe₂ Nanosheets with Lattice Distortion for Highly Efficient Overall Water Splitting

Exploring highly efficient and low‐cost electrocatalysts for electrochemical water splitting is of importance for the conversion of intermediate energy. Herein, the synthesis of dual‐cation (Fe, Co)‐incorporated NiSe 2 nanosheets (Fe, Co‐NiSe 2 ) and systematical investigation of their electrocatalytic performance for water splitting as a function of the composition are reported. The dual‐cation incorporation can distort the lattice and induce...
