Transition metal phosphides (TMPs) are promising electrocatalysts for hydrogen evolution reaction (HER) in water electrolysis. This review details strategies for enhancing TMP catalysts from nanostructures to single atoms, offering design principles for improved hydrogen production.
Area of Science:
- Materials Science
- Electrochemistry
- Catalysis
Background:
- Transition metal phosphides (TMPs) show potential as electrocatalysts for the hydrogen evolution reaction (HER).
- Enhancing HER performance requires optimizing TMP microstructure, but design principles are lacking.
