Hydrogen can serve as a clean fuel, and electrochemical water splitting through the hydrogen evolution reaction is one way to generate this valuable resource. Many current electrocatalysts for the hydrogen evolution reaction are based on platinum, which, although expensive, can be very efficient. Researchers are always looking to improve the efficiency of platinum electrocatalysts to make the hydrogen evolution reaction a suitable replacement for fossil fuels.
