Abstract : The quest for sustainable energy sources has accelerated the exploration of water splitting as a method of clean hydrogen production. Among the various electrocatalysts designed to drive water splitting, noble metal–based electrocatalysts have recently emerged as promising candidates. This review highlights the recent developments in noble metal–based electrocatalysts for overall water splitting. These electrocatalysts integrate the exceptional catalytic properties of noble metals, such as platinum, iridium, and ruthenium, with diverse materials, including transition metals, carbon substrates, and metal oxides, to enhance their efficiency, stability, and cost-effectiveness. This review discusses recent developments on noble metals such as platinum, palladium, rhodium, ruthenium, iridium, and noble metal–based hybrid materials as bifunctional electrocatalysts for overall water splitting. In addition, the existing obstacles and prospects for bifunctional water-splitting electrocatalysts are also focused.
