Global Oxygen Evolution Catalyst Market Strategic Research Report

Scope of the Report

The global Oxygen Evolution Catalyst market size is predicted to grow from US$ 93.91 million in 2025 to US$ 587 million in 2032; it is expected to grow at a CAGR of 29.0% from 2026 to 2032.

Oxygen evolution reaction (OER) catalysts are functional catalytic materials used to promote the electrochemical oxygen evolution reaction. They are primarily deployed at the anode or positive electrode of water electrolysis hydrogen production systems, electrochemical CO₂ conversion systems, metal-air batteries, and regenerative fuel cells. Commercially, the dominant catalysts are iridium oxide, iridium black, and iridium-based mixed oxides used in acidic PEM electrolyzers, while alkaline and AEM systems are increasingly adopting non-precious-metal oxides or hydroxides based on nickel–iron, cobalt–iron, and related compositions. The product's overall gross margin is approximately 35%.

OER catalysts remain a small-volume, high-value, high-growth category of critical hydrogen-energy materials, with demand primarily driven by the scale-up of PEM and AEM water electrolysis systems. As electrolyzer deployment accelerates, catalyst performance increasingly determines stack efficiency, precious metal consumption, operating lifetime, and overall hydrogen production economics.

The competitive landscape is led by precious metal and electrocatalyst companies. European, Japanese, and U.S. suppliers maintain advantages in iridium-based catalyst technology, precious metal recycling, and customer qualification, while Chinese companies are rapidly expanding through localization, fast sampling, and integrated membrane-electrode assembly (MEA) supply capabilities. For customers, the most important considerations are not simply catalyst price, but durability at low iridium loading, hydrogen-in-oxygen control, batch-to-batch consistency, coating processability, and compatibility with large-scale MEA manufacturing.

Over the next six years, the market is expected to maintain strong growth potential, although expansion will be influenced by the pace of green hydrogen project deployment and constraints in global iridium supply. Acidic PEM systems will continue to rely on iridium-based catalysts, with technological development focused on ultra-low iridium loading, supported IrOx catalysts, iridium–ruthenium mixed oxides, and closed-loop precious metal recycling. Meanwhile, AEM and alkaline systems will drive growth in non-precious-metal OER catalysts, although most of these technologies remain in demonstration, pilot-scale deployment, and customer qualification stages in the near term.
