Surface phosphorization of Ni-Co-S as an efficient bifunctional electrocatalyst for full water splitting.

Exploring efficient bifunctional electrocatalysts is of great importance for water splitting to obtain scalable and sustainable hydrogen generation. The strategy of element modification is effective for tuning the electronic structures of electrocatalysts. Herein, binder-free, phosphorus-doped NiCoS/CFP (Ni-Co-S-P) was synthesized under hydrothermal conditions, followed by surface phosphorization solid reaction.
