Trance Amount of Ir Decorated NiFe Phosphide In‐Situ Grown on Carbon Cloth as Cost‐Effective Electrocatalyst for Oxygen Evolution Reaction

Cost-effective electrocatalysts is a key constituent to establish the balance of cost and catalytic efficiency for oxygen evolution reaction (OER) via water electrolysis in the area of energy conversion and storage. NiFe phosphide decorated with trace amount of iridium (Ir) species in-situ grown on carbon cloth was prepared by a facile wet chemistry approach followed by a phosphorization post-treatment at a relative low temperature. The optimal electrocatalyst, Ir
