Researchers split water by altering photosynthetic machinery in plants; semi-artificial photosynthesis

Green Car Congress

They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies. Their method also managed to absorb more solar light than natural photosynthesis. This could be a great platform for developing solar technologies. —Katarzyna Sokó?.

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. An open-access paper on the work is published in Nature Communications. —Zhang et al.

New mesocrystal photocatalyst enhances light-driven hydrogen production

Green Car Congress

at 360 nm in overall water splitting and even good durability up to 1 day. When light is applied to photocatalysts, electrons and holes are produced on the surface of the catalyst; hydrogen is obtained when these electrons reduce the hydrogen ions in water. The mesocrystal also exhibits a high quantum yield of 6.7%

Rice team demonstrates plasmonic hot-electron solar water-splitting technology; simpler, cheaper and efficient

Green Car Congress

Researchers at Rice have demonstrated an efficient new way to use solar energy for water splitting. In contrast to past work, the new architecture does not utilize a Schottky junction—the commonly used building block to collect hot carriers. b) Energy schematic of the structure. —Robatjazi et al.

Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

As coal plants close, they leave behind empty building shells and scores of lost jobs. Such a conversion has never been done, but the report is another sign that the idea is gaining momentum—if with the slow steps of a baby needing decades to learn to walk. “A Conversion backers say the process has benefits for everybody involved.
