Hydrogen Water Fuel

A team of computational scientists from our very own University of Kentucky (GO
CATS!) in collaboration with the University of Louisville have come up with a
way to generate hydrogen fuel from water using sunlight. There findings
published in Physical Review B show that the seemingly straightforward, but
currently energy intensive, process of splitting water molecules into its
chemical components can be achieved using a new metal alloy catalyst. The
authors show that the new alloy, gallium nitrate (GaN) with 2% substitution of
antimony (Sb), has the right electrical properties that allow solar energy to
hydrolyze water into hydrogen and oxygen through photoelectrochemical (PEC)
splitting of water.
"Previous research on PEC has focused on complex materials," Menon said. "We
decided to go against the conventional wisdom and start with some
easy-to-produce materials, even if they lacked the right arrangement of
electrons to meet PEC criteria. Our goal was to see if a minimal 'tweaking' of
the electronic arrangement in these materials would accomplish the desired
results."
Right now this is a complex theoretical model, but it's a proof of concept
none-the-less. Not to mention, a reason to fund and support science AS A WHOLE
instead of particular sects of research. What's interesting are the major
implications for future research into solar energy, and production of hydrogen
fuel. This could open the doors to a wide variety of uses for a more economic
source of carbon-free energy. Hopefully if future experiments with this material
pan out, this could create an even bigger market for clean energy.
