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. —Katarzyna Sokó?, first author and PhD student at St John’s College.

Researchers devise photochemical process to convert bio-acetone to green jet fuel additive

Green Car Congress

Researchers at Los Alamos National Laboratory (LANL), with colleagues at Yale University, have developed a photochemical process to convert acetone derived from plants (bio-acetone) into a mixture of polycyclic alkanes, the high energy density of which is appropriate for high-perfomance aviation applications.

Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

A research team has developed a new artificial photosynthesis device component with remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels: ethylene and hydrogen. The Advanced Light Source, Molecular Foundry, and NERSC are user facilities at Berkeley Lab.

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. times more light. Chen et al.

Volkswagen 2.0 TDI diesel for Euro 6d; SCR twin-dosing

Green Car Congress

Volkswagen opted for a dual strategy: detailed measures optimized the combustion process and reduced raw emissions, while twin dosing technology in the exhaust gas system converted the majority of NO x into harmless substances. The first SCR catalytic converter is installed directly downstream of the engine. As previously, the 2.0
