University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.

Rice team develops plasmonic photocatalyst for one-step light-driven conversion of H2S to hydrogen and sulfur

Green Car Congress

Known as the Claus process, it produces sulfur but no hydrogen, which it instead converts into water. The plasmonic hydrogen sulfide remediation technology has been licensed by Syzygy Plasmonics, a Houston-based startup company with more than 60 employees, whose co-founders include Halas and Nordlander.

Study finds paved surfaces in Houston worsen air quality

Green Car Congress

Paved surfaces in the Houston area keep the city warmer than more natural surfaces. ““The very existence of the Houston area favors stagnation.” The research team combined extensive atmospheric measurements with computer simulations to examine the impact of pavement on breezes in Houston.
