A Japanese team is working on a solar water splitting system with a 12% solar-to-hydrogen efficiency, while UK researchers have identified the reason why graphene’s dense crystalline structure is much ...

Hydrogen can be produced by electrolysis of water, ideally with solar cells or wind power providing the electrical energy required. This "green" hydrogen is expected to play an important role in the ...

Researchers in the Netherlands have designed a water-splitting system with an electrochemical cell and a 25%-efficient tandem perovskite-silicon solar cell. It can reportedly achieve a ...

Researchers have created a floating, solar-powered device that converts contaminated water or seawater into clean hydrogen fuel and drinking water. Because it works with any open water source and ...

Artificial photosynthesis provides a way to store solar energy in chemical bonds. Achieving water splitting without an applied external potential bias provides the key to artificial photosynthetic ...

University of Alberta (U of A) researchers have discovered a method to harness sunlight and specialized materials to cleanly and efficiently split water into hydrogen and oxygen. If scaled, this could ...

Scientists in India said they have developed a scalable next-generation device that produces green hydrogen by splitting water molecules using only solar energy. A group at the Bengaluru-based Centre ...

The effective deposition of finely dispersed cobalt oxide (CoOx) nanoparticles within the mesoporous framework of the WO₃-F127 electrode is illustrated in this figure. The incorporation of CoOx takes ...

A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers. A floating, ...

Sunlight can be used to produce green hydrogen directly from water in photoelectrochemical (PEC) cells. So far, most systems based on this 'direct approach' have not been energetically competitive.
