Electrocatalysts for Energy Conversion

Electrocatalysts are materials that speed up chemical reactions driven by electricity, and they sit at the heart of technologies that convert renewable energy into storable fuels or usable power. In devices like fuel cells and water electrolyzers, reactions such as oxygen reduction and hydrogen evolution are sluggish without the right catalyst, making the choice of material a central bottleneck for efficiency and cost. Researchers are actively developing nanomaterials and novel catalyst compositions to push these reactions faster while reducing reliance on scarce precious metals like platinum. Key open questions include how atomic-scale catalyst structure governs reaction selectivity, and how to maintain performance over thousands of operating cycles under real-world conditions.
