Biomass‑derived graphene boosts ultra‑low iridium OER catalyst for PEM electrolysis
Researchers have developed a new graphene-based electrocatalyst using biomass-derived materials to improve the efficiency of PEM water electrolysis. This innovation allows for high performance while significantly reducing the amount of expensive iridium required for the process.
Why it matters
Reducing reliance on scarce noble metals like iridium is critical for making green hydrogen production more cost-effective and scalable.
Researchers from China's Yunnan Normal University, the State Key Laboratory of Advanced Metallurgy for Non-ferrous Metals and Kunming University of Science and Technology have developed a graphene-based electrocatalyst that delivers efficient oxygen evolution reaction (OER) performance while using an ultra-low amount of iridium. The work showcases how biomass-derived graphene can actively boost catalytic activity and, at the same time, reduce dependence on scarce noble metals.
