Scientists Come Up With New Process For Hydrogen Water Splitting

Oil Price · Brian Westenhaus · last updated

A City University of Hong Kong research team has successfully mediated poor charge carrier transport at low voltage by adding phosphorus to a metal oxide catalyst.

Metal oxides are a promising catalyst for photoelectrochemical (PEC) water splitting to produce hydrogen as an alternative fuel. However, their effectiveness is restricted at low voltage. Adding phosphorus reduced energy losses during water splitting.

Their findings were published in the scientific journal Nature Communications, titled “Low-bias photoelectrochemical water splitting via mediating trap states and small polaron hopping.”

State of Play

Hydrogen, long seen as a theoretical if not practical alternative to petroleum-based transportation fuels, is once again having a day in the sun as industries promote “green hydrogen,” produced using renewable resources.
