Water and some nano-structured iron oxide is all it takes to produce bubbles of solar hydrogen. EPFL and Technion scientists just discovered the champion structure to achieve this In the quest for the production of renewable and clean energy, photoelectrochemical cells (PECs) constitute a sort of a Holy Grail. PECs are devices able of splitting water molecules into hydrogen and oxygen in a single operation, thanks to solar radiation. "As a matter of fact, we've already discovered this...

Algal protein gives boost to electrochemical water splitting Water splitting in photo-electrochemical cells to yield hydrogen is a promising way to sustainable fuels. A team of Swiss and US scientists now made major progress in developing highly efficient electrodes — made of an algal protein, thus mimicking a central step in natural photosynthesis. Photosynthesis is considered the «Holy Grail» in the field of sustainable energy generation because it directly converts...

Using advanced theoretical computations, a team of Kentucky scientists has derived a means to "tweak" an inexpensive semiconductor to function as photoelectrochemical catalyst. Scientists from the University of Kentucky and the University of Louisville have determined that an inexpensive semiconductor material can be "tweaked" to generate hydrogen from water using sunlight. The research, funded by the U.S. Department of Energy, was led by Professors Madhu Menon and R. Michael Sheetz at...

This discovery will make it possible to improve photoelectrochemical cells. In the same way that plants use photosynthesis to transform sunlight into energy, these cells use sunlight to drive chemical reactions that ultimately produce hydrogen from water. The process involves using a light-sensitive semi-conducting material such as cuprous oxide to provide the current needed to fuel the reaction. Although it is not expensive, the oxide is unstable if exposed to light in water. Research by...

By Emil Venere, Purdue University Researchers are creating a new type of solar cell designed to self-repair like natural photosynthetic systems in plants by using carbon nanotubes and DNA, an approach aimed at increasing service life and reducing cost. "We've created artificial photosystems using optical nanomaterials to harvest solar energy that is converted to electrical power," said Jong Hyun Choi, an assistant professor of mechanical engineering at Purdue University. The design exploits...
