Transition metal phosphides (TMPs) and chalcogenides (TMCs) show great promise as efficient electrocatalysts for the oxygen evolution reaction (OER). These non-oxide materials offer superior performance compared to traditional catalysts in water electrolysis and energy storage devices.
Area of Science:
- Electrochemistry
- Materials Science
Background:
- The oxygen evolution reaction (OER) is crucial for energy storage and conversion devices like water electrolyzers and metal-air batteries.
- Developing efficient, cost-effective, and durable OER electrocatalysts is a significant challenge in applied electrochemistry.
Purpose of the Study:
- To summarize recent advancements in transition metal phosphide (TMP) and transition metal chalcogenide (TMC) based OER electrocatalysts.
- To discuss the electrochemical stability and performance of these non-oxide catalysts.
Main Methods:
- Review of recent literature on TMP and TMC OER electrocatalysts.
- Analysis of electrochemical stability using Pourbaix diagrams.
- Examination of morphological, structural, and compositional evolution under OER conditions.
Main Results:
- TMPs and TMCs exhibit outstanding OER performance, surpassing conventional oxide/hydroxide catalysts in alkaline water electrolysis.
- These materials show potential to replace noble metals in proton-exchange membrane (PEM) water electrolysis.
- Electrochemical stability and material evolution under OER conditions are key factors.
Conclusions:
