A water-splitting cell built without platinum or any other precious metal has now run continuously for more than 1,000 hours at the kind of electrical throughput that commercial hydrogen plants demand ...

The photoelectrochemical (PEC) overall water-splitting reaction (OWS) has been fully developed in the past decade, especially in the new catalysts, characterization methods and reaction mechanisms.

Electrochemical water splitting employs electrical energy to drive the decomposition of water into hydrogen and oxygen at paired electrodes immersed in an electrolyte. At the cathode, protons or water ...

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 ...

Figure 1. Illustrations of a trifunctional graphene-sandwiched heterojunction-embedded layered lattice (G-SHELL) structure. Schematic representation of a) synthesis procedures of G-SHELL from a ...

Scientists in Korea have built a green hydrogen system prototype that embeds a PV generation unit based on photoanodes made of perosvksite solar cells. The device purportedly achieved a ...
