Star-shaped gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods—opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to Rutgers University-New Brunswick researchers.

"Instead of using ultraviolet light, which is the standard practice, we leveraged the energy of visible and infrared light to excite electrons in gold nanoparticles," said Laura Fabris, associate professor in the Department of Materials Science and Engineering in the School of Engineering who led the work with Fuat Celik, assistant professor in the Department of Chemical and Biochemical Engineering. "Excited electrons in the metal can be transferred more efficiently into the semiconductor, which catalyzes the reaction."

The researchers, whose study was published online today in the journal Chem, focused on photocatalysis, which typically means harnessing sunlight to make faster or cheaper reactions.

Titanium dioxide illuminated by ultraviolet light is often is used as a catalyst, but using ultraviolet light is inefficient.

In the study, Rutgers researchers tapped visible and infrared light that allowed gold nanoparticles to absorb it more quickly and then transfer some of the electrons generated as a result of the light absorption to nearby materials...
