Purple sunlight eaters

erspersed in the titanium dioxide matrix. "The platinum nanoparticles are essential for creating a distinct spot for the production of the hydrogen molecule," said Peng Wang, an Argonne postdoctoral researcher in Rozhkova's group at Argonne's Center for Nanoscale Materials.

"It is interesting that in biology, bacteriorhodopsin does not naturally participate in these kind of reactions," Rozhkova said. "Its natural function really doesn't have much to do at all with creating hydrogen. But as part of this hybrid, it helps make hydrogen under white light and at environmentally friendly conditions."

This bio-assisted hybrid photocatalyst outperforms many other similar systems in hydrogen generation and could be a good candidate for fabrication of green energy devices that consume virtually infinite sources salt water and sunlight.
