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.

New mesocrystal photocatalyst enhances light-driven hydrogen production

Green Car Congress

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. As a result, it has a more efficient conversion rate for producing hydrogen than conventional nanoparticulate photocatalysts.

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

French team finds light-driven algal enzyme that converts fatty acids to hydrocarbons

Green Car Congress

A team of researchers in France has discovered an algal photoenzyme that catalyzes the decarboxylation of free fatty acids to n-alkanes or -alkenes in response to blue light. Many organisms—photosynthetic and nonphotosynthetic—use light for processes such as growth, development, and metabolism. variabilis or C.

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

Green Car Congress

The three-part composite maximizes both absorbing light and its efficiency for water splitting. Finally, the gold-covered LTO is mixed with ultrathin sheets of the element black phosphorus (BP), which acts as a light absorber. The band gap properties are promising because of broad solar light absorption from UV to NIR region.

ICCT working paper highlights benefits of current and emerging light-duty diesel technology; “promising pathway for compliance”

Green Car Congress

Diesel vehicles have had a rough time penetrating the US light-duty vehicle market, reflecting outdated negative perceptions, higher fuel prices for diesel than for gasoline, the cost of complying with stringent US emission standards, and rapidly improving gasoline engines. —Isenstadt and German (2017).
