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 demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

Researchers from the University of Strathclyde and the University of St. is well known that some higher plants can synthesize ammonia or its derivatives directly from air and water at room temperature. To the best of our knowledge, there is no report on artificial synthesis of ammonia direct from air and water.

Chalmers, SSPA researchers advance method for further developing hydrofoils for electric vessels

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have created a unique method for further developing hydrofoils that can significantly increase the range of electric vessels and reduce the fuel consumption of fossil-powered ships by 80%. An open-access paper on their work is published in the Journal of Marine Science and Engineering.

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. The carbon or charcoal powders were dispersed in distilled water at a ratio of 25.8 mL volume of water.

Duke team develops new core-shell copper nanowire catalyst for efficient water oxidation for solar fuels

Green Car Congress

A transparent film of copper nanowires was transformed into an electrocatalyst for water oxidation by electrodeposition of Ni or Co onto the surface of the nanowires. Water oxidation (2H 2 O → O 2 + 4 e- + 4H + ) is a key step for converting solar energy into chemical fuels. Chen et al. Click to enlarge. A team led by Benjamin J.

Researchers demonstrate water splitting to generate hydrogen using ultra-small Si nanoparticles

Green Car Congress

A team of researchers from the University at Buffalo (SUNY) have demonstrated that hydrogen generation from ultra-small silicon nanoparticles (10 nm diameter) proceeds much more rapidly than expected based upon extrapolation of rates obtained using larger particles.

University of Texas researchers develop new solar photoelectrosynthetic process to convert CO2 to methanol

Green Car Congress

Researchers from The University of Texas at Arlington are developing a new process for photoelectrosynthesis of methanol—the conversion of carbon dioxide to methanol using sunlight and hybrid CuO–Cu 2 O semiconductor nanorod arrays. In the lab, they submerged those rods in a water-based solution rich in CO 2.
