Promising News For Solar Fuels from Berkeley Lab Researchers
2014-03-07 15:04:01

Berkeley Lab There’s promising news from the front on efforts to produce  fuels through artificial photosynthesis. A new study by Berkeley Lab researchers at the Joint Center for Artificial Photosynthesis (JCAP) shows that nearly 90-percent of the electrons generated by a hybrid material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules. Gary Moore, a chemist and principal investigator with Berkeley Lab’s Physical Biosciences Division, led...

Researchers Identify Key Intermediate Steps In Artificial Photosynthesis Reaction

Lynn Yarris, Berkeley Lab Artificial photosynthesis, in which we emulate the process used by nature to capture energy from the sun and convert it into electrochemical energy, is expected to be a major asset in any sustainable energy portfolio for the future. Artificial photosynthesis offers the promise of producing liquid fuels that are renewable and can be used without exacerbating global climate change. A key to realizing commercial-scale artificial photosynthesis technology is the...

Artificial Leaf Jumps Developmental Hurdle
2014-02-19 13:11:38

Arizona State University In a recent early online edition of Nature Chemistry, ASU scientists, along with colleagues at Argonne National Laboratory, have reported advances toward perfecting a functional artificial leaf. Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is one of the goals of BISfuel – the Energy Frontier Research Center, funded by the Department of Energy, in the Department of Chemistry and...

Splitting Water Into Hydrogen And Oxygen Using Nanoparticles, Sunlight
2013-12-16 04:24:52

Lee Rannals for redOrbit.com - Your Universe Online University of Houston researchers, writing in the journal Nature Nanotechnology, report they have found a catalyst that can quickly generate hydrogen from water using sunlight, potentially creating a clean and renewable energy source. The study involved the use of cobalt oxide nanoparticles to split water into hydrogen and oxygen. Jiming Bao, lead author of the paper and an assistant professor in the Department of Electrical and...

Method Developed To Make Hydrogen Fuel From Sunlight
2013-08-29 15:41:47

Lawrence Berkeley National Laboratory Berkeley Lab Researchers at Joint Center for Artificial Photosynthesis Make Unique Semiconductor/Catalyst Construct In the search for clean, green sustainable energy sources to meet human needs for generations to come, perhaps no technology matches the ultimate potential of artificial photosynthesis. Bionic leaves that could produce energy-dense fuels from nothing more than sunlight, water and atmosphere-warming carbon dioxide, with no byproducts...

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...

Wonder Material May Be Able To Tackle Environmental Challenges
2013-03-21 05:12:45

Lee Rannals for redOrbit.com - Your Universe Online Scientists have succeeded in creating a new material that is capable of generating hydrogen, producing clean water and creating energy. Nanyang Technological University (NTU) researchers created a single nanomaterial that can be used as a flexible water filtration membrane, to help recover energy from desalination waste brine, be made into flexible solar cells, and can double the lifespan of lithium ion batteries. The Multi-use...

A University of Central Florida chemist has come up with a unique way to kill certain cancer cells — give them acid reflux. Chemistry professor Kevin Belfield used a special salt to make cancer cells more acidic — similar to the way greasy foods cause acid reflux in some people. He used a light-activated, acid-generating molecule to make the cells more acidic when exposed to specific wavelengths of light, which in turn kills the bad cells. The surrounding healthy cells stay...

Light-based Hydrogen Production Substantially Improved
2012-11-09 08:56:20

[ Watch The Video ] University of Rochester Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is adding to its appeal by increasing the output and lowering the cost of current light-driven hydrogen-production systems. The work, funded by the U.S. Department of Energy, was led by chemistry professors Richard Eisenberg, Todd Krauss, and Patrick Holland,...
