ANEMEL researchers have made a significant breakthrough in green hydrogen production by creating a PGM-free catalyst for water electrolysis. The catalyst, developed at the École Polytechnique Fédérale de Lausanne in Switzerland, is made from nickel and molybdenum, abundant metals that replace scarce platinum group metals typically used in electrolyzers. By utilizing electrodeposition on carbon paper, the researchers achieved a high-performing catalyst that operates stably at high current densities, rivaling platinum catalysts in activity and surpassing them in stability. This innovation not only reduces costs and waste in electrolyzer production but also paves the way for large-scale green hydrogen production. The structural changes observed during the reaction, where molybdenum atoms migrate to the surface, enhance water-splitting efficiency, bringing the industry closer to efficient and sustainable hydrogen generation.
