Heteroatom-Doped Transition Metal Electrocatalysts for Hydrogen Evolution Reaction

Developing efficient and low-cost electrocatalysts for the hydrogen evolution reaction (HER) is important for clean energy systems. Non-noble transition metals are the most promising candidates for replacement of conventional Pt group catalysts for the HER. However, most non-noble metals show poor HER activity due to their intrinsic electronic structures. Herein, we use a multifaceted heteroatom doping method (nitrogen, sulfur, and phosphorus) to directly and continuously fine-tune the electronic structure and HER activity of non-noble metals without changing their chemical composition. As a proof-of-concept, a nitrogen and phosphorus dual-doped Ni catalyst is explored by precisely manipulating doping modes,…
