Abstract
Developing highly efficient and stable acidic oxygen evolution reaction (OER) catalysts is crucial for water electrolysis hydrogen production. However, commercial iridium-based and ruthenium-based oxides (IrO2 and RuO2) face challenges of high costs and insufficient durability, making the development of cost-effective, high-performance, and stable electrocatalysts particularly significant. This study systematically discusses the enhancement of OER catalytic activity and stability of IrO2 and RuO2 through transition metal doping (3d, 4d, 5d, and multi-metal), which can modify electronic structures and optimize d-band centers. This work elucidates the structure-activity relationships in transition metal doped Ir/Ru oxides, revealing future opportunities in non-noble metal doping strategies and atomic-level design to achieve high-performance and economical acidic OER catalysts.
期刊介绍：
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
