Scientists combined a pigment with semiconducting nanoparticles to create a system that uses light to spark a catalytic process that creates hydrogen fuel.  Argonne nanoscientist Elena Rozhkova and her colleagues combined a pigment called bacteriorhodopsin, a protein found in the membranes of ancient microorganisms that live in desert salt flats, with sunlight to generate environmentally […]

Researchers at University College London (UCL) have broken through to understanding of the properties of titanium dioxide known as ‘titania’ that is hoped to be used in photoelectrochemical cells known as PECs. The basis of the research clears up a decades old misunderstanding that’s clouded the knowledge of how mixed phase titania catalysts operate.  Mixed […]

In a reversal of momentum in research back to inexpensive materials and easily scalable production processes, Kevin Sivula and his colleagues at Ecole Polytechnique Fédérale de Lausanne (EPFL) are enabling an economically viable method for solar hydrogen production. There new device, while still in an experimental stage is the focus of a description in an […]

Chemical reactions on the surface of metal oxides, such as titanium dioxide and zinc oxide, are in for a new look.  Chemical reactions that change the oxidation state of molecules on the surface of metal oxides have been seen historically as a transfer solely of electrons. The new research shows that, at least in some […]

Colleagues from the universities of St. Andrews in Scotland and Bochum and Helmholtz-Forschungszentrum in Berlin, with scientists at KIT’s Institute for Functional Interfaces, headed by Professor Christof Wöll, have succeeded in gathering new findings on the fundamental mechanisms of photochemistry on titanium dioxide (TiO2). Solar energy as a power source with its direct conversion into […]
