Doping Sulfur in Layered Double Hydroxides with High Hydrophilicity to Accelerate the Charge Transfer and Reduce the Energy Barrier for Efficient Electrocatalytic Splitting Water

Nowadays, water splitting has been recognized as one of the most attractive ways to produce clean hydrogen energy. Herein, a novel sulfur-doped layered double-hydroxide (namely, S-NiCo-LDH) electrocatalyst with nanocage structure is prepared. After the etching treatment with Ni ions, the spatial structure of the catalysts is opened, and the hydrophilicity is improved, which will enhance the adsorption capacity for H
