Electrocatalysts: Pt Dopant: Controlling the Ir Oxidation States toward Efficient and Durable Oxygen Evolution Reaction in Acidic Media (Adv. Funct. Mater. 38/2020)

The balance of Ir oxidation states between 3+ and 4+ is crucial to the stability of Ir oxide‐based oxygen evolution reaction (OER) catalysts. In article number 2003935, ll Choi, Kwangyeol Lee, and co‐workers directly link the Pt doping level and mode of Ir oxide to the stability of Ir catalysts. The...

Zusammenfassung:The balance of Ir oxidation states between 3+ and 4+ is crucial to the stability of Ir oxide‐based oxygen evolution reaction (OER) catalysts. In article number 2003935, ll Choi, Kwangyeol Lee, and co‐workers directly link the Pt doping level and mode of Ir oxide to the stability of Ir catalysts. The cover depicts the Pt‐doped IrOx‐based nanoframe as a stable OER catalyst under acidic conditions, which produces green hydrogen via electrolytic water splitting.
