Bifunctional Hybrid Ni/Ni2P Nanoparticles Encapsulated by Graphitic Carbon Supported with N, S Modified 3D Carbon Framework for Highly Efficient Overall Water Splitting

After high temperature annealing, the product is obtained, and its electrochemical performance is tested using the Chenhua 760E equipment;• Data collection time: 2017.08-2018.04;• Table data: literature performance comparison data• Some individual data may not be retained;• There are errors in individual data.

The reasons for introducing errors include: differences in N and S content of commercial melamine sponge, temperature control of annealing tubular furnace, differences in intrinsic resistance of electrode, and differences in sensitivity of electrochemical workstation itself;
