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

Its electrochemical performance was tested by Chenhua 760E equipment;• Data collection time: 2017.05-2018.06;• Table data: ICP content of each element in the product, exchange current density calculation, literature performance comparison data;• Some individual data may not be retained;• There are errors in individual data.

The reasons for introducing errors include: temperature control of annealing tube furnace, difference in intrinsic resistance of electrode, difference in sensitivity of electrochemical workstation, etc;
