Molybdenum oxide/nickel molybdenum oxide heterostructures hybridized active platinum co-catalyst toward superb-efficiency water splitting catalysis.

A new catalyst has been developed that utilizes molybdenum oxide (MoO)/nickel molybdenum oxide (NiMoO) heterostructured nanorods coupled with Pt ultrafine nanoparticles for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) toward industrial-grade water splitting. This catalyst has been synthesized using a versatile approach and has shown to perform better than noble-metals catalysts, such as Pt/C and RuO, at industrial-grade current level (≥1000 mA·cm). When used simultaneously as a cathode and anode, the proposed material yields 10 mA·cm at a remarkably small cell voltage of 1.
