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.

CU-Boulder team develops more efficient isothermal solar-thermal water splitting technique for H2 production

Green Car Congress

A University of Colorado Boulder team has developed a new solar-thermal water-splitting (STWS) system for the efficient production of hydrogen. STWS cycles have long been recognized as a desirable means of generating hydrogen gas (H 2 ) from water and sunlight, the team notes. Christopher L. Muhich, Brian W. Evanko, Kayla C.

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.

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.
