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.

Researchers produce hydrogen from water and charcoal mix at room temperature using laser pulses

Green Car Congress

Researchers at Wakayama University in Japan have produced a mixture of hydrogen and carbon monoxide gas by irradiating a mixture of carbon powder and distilled water with intense nanosecond laser pulses at room temperature. Electrodes or any other photocatalysts were not used to produce the hydrogen. mL volume of water.

Virginia Tech team develops process for high-yield production of hydrogen from xylose under mild conditions

Green Car Congress

Percival Zhang, has developed a process to convert xylose—the second-most abundant sugar in plants—into hydrogen with approaching 100% of the theoretical yield. In the process, hydrogen is produced from xylose and water in one reactor containing 13 enzymes, including a novel polyphosphate xylulokinase (XK).

Brookhaven team develops molybdenum-soy catalyst that rivals performance of noble metals for hydrogen production

Green Car Congress

This illustration depicts the synthesis of a new hydrogen-production catalyst from soybean proteins and ammonium molybdate. The hybrid material effectively catalyzes the conversion of liquid water to hydrogen gas while remaining stable in an acidic environment. One key step is splitting water (water electrolysis).
