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%. They report on their work in a paper in the journal Nature Nanotechnology.

Researchers show how bacteria convert toxic copper ions to stable metallic copper

Green Car Congress

Researchers from the University of Houston, with colleagues at the University of São Paolo in Brazil, have demonstrated how copper-resistant bacterium from a copper mine in Brazil convert CuSO 4 (copper sulfate) ions into zero-valent Cu (metallic copper). An open-access paper on their research is published in Science Advances.

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.
