Hydrogen (H 2) is a promising fuel for reducing greenhouse gases, especially if produced by using renewable energy to split water molecules (H 2 O). But as simple as it may seem to break water into ...

Solar water splitting is one of the most direct ways to produce green hydrogen using sunlight. However, most photocatalysts and photoelectrodes absorb only a limited portion of solar radiation, mainly ...

A new study has revealed key factors limiting the efficiency of photoelectrochemical water splitting using a titanium dioxide photoanode for clean hydrogen production. Researchers combined ...

Scientists led by Professor Yulong Ding have demonstrated it is possible to reduce the temperature of thermochemical splitting, where a catalyst splits water into hydrogen and oxygen, by 500 o C by ...

Photocatalytic water splitting is a clean energy technology that uses sunlight to split water into oxygen and hydrogen in order to produce green hydrogen—a clean fuel—without relying on fossil fuels.

University of Michigan researchers developed a new photocatalytic water splitting system that is reportedly able to reach a 9.2% solar-to-hydrogen (STH) efficiency. The proposed system uses the higher ...

Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have ...
