UH team develops new, highly efficient and durable OER catalyst for water splitting

Green Car Congress

Researchers at the University of Houston have developed a catalyst—composed of easily available, low-cost materials and operating far more efficiently than previous catalyst—that can split water into hydrogen and oxygen. Our discovery may lead to a more economic approach for hydrogen production from water electrolysis.
