A platinum-free hydrogen catalyst hits industrial benchmarks for 1,000 hours
Researchers at Washington University in St. Louis report a phosphide-based catalyst for water electrolysis that ran for 1,000 hours at industry-standard conditions without relying on platinum-group metals.
Key Takeaways
- The study describes a catalyst made from two phosphides for an anion-exchange membrane water electrolyzer.
- Researchers said it outperformed a state-of-the-art comparison cathode and a platinum-group-metal benchmark.
