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%. Different sources of light were used, ranging from a laser to white light simulating the solar spectrum. doi: 10.1038/nnano.2013.272.

Researchers in POWERFUL develop new two-stroke diesel featuring low consumption and low criteria emissions

Green Car Congress

The objective of POWERFUl was to design engines for light-duty urban and micro-urban vehicles (segment A and B), capable of reducing CO 2 and criteria pollutant emissions. This entails a significant saving in fuel consumption, as well as a reduction in the cost of the engine itself. Benajes, J., Novella, R., and De Lima, D.
