Light over heat: UV-driven rhodium nanoparticles catalyze conversion of CO2 to methane

Green Car Congress

Duke University researchers have engineered rhodium nanoparticles that can harness the energy in ultraviolet light and use it to catalyze the conversion of carbon dioxide to methane, a key building block for many types of fuels. So we get to choose how the reaction goes with light in a way that we can’t do with heat.

Cambridge team demonstrates light-driven photoreforming of unprocessed biomass to H2 at room temperature

Green Car Congress

A team of scientists at the University of Cambridge has reported the light-driven photoreforming of cellulose, hemicellulose and lignin to H 2 using semiconducting cadmium sulfide quantum dots in alkaline aqueous solution. CdS is an inexpensive, visible-light-absorbing photocatalyst with a bulk electronic bandgap of around 2.4

New mesocrystal photocatalyst enhances light-driven hydrogen production

Green Car Congress

The discovery was made by a joint research team led by Associate Professor Takashi Tachikawa (Molecular Photoscience Research Center, Kobe University) and Professor Tetsuro Majima (Institute of Scientific and Industrial Research, Osaka University). Their findings were published in the journal Angewandte Chemie International Edition.

Elemental boron effective photothermocatalyst for the conversion of CO2 for fuels and chemicals

Green Car Congress

Researchers in Japan and China developed an efficient method for CO 2 reduction over elemental boron catalysts in the presence of only water and light irradiation through a photothermocatalytic process. A paper on their work is published in the journal Angewandte Chemie. When the sun shines on a surface, it is heated. —Jinhua Ye.

Scientists develop method for direct conversion of methane to methanol or acetic acid under mild conditions

Green Car Congress

Researchers at Argonne National Laboratory, Tufts University and Oak Ridge National Laboratory have shown that mononuclear rhodium species, anchored on a zeolite or titanium dioxide support suspended in aqueous solution, can catalyze the direct conversion of methane to methanol and acetic acid using oxygen and carbon monoxide under mild conditions.

Osaka team develops new solar-to-hydrogen catalyst that uses broader spectrum of light

Green Car Congress

A team at Osaka University in Japan has developed a new material based on gold and black phosphorus to harvest a broader spectrum of sunlight for water-splitting to produce hydrogen. The three-part composite maximizes both absorbing light and its efficiency for water splitting. The LTO surface is partly coated with gold nanoparticles.

New efficient biphasic catalytic process for conversion of biomass to dense jet-range fuels

Green Car Congress

Now, researchers from the University of Nevada and Washington State University have developed a novel efficient biphasic tandem catalytic process (biTCP) for synthesizing cycloalkanes from renewable terpenoid biomass (such as 1,8-cineole).
