Argonne team combines two protein complexes to make hydrogen fuel from water

Green Car Congress

Researchers from the US Department of Energy’s (DOE) Argonne National Laboratory have combined two membrane-bound protein complexes to perform a complete conversion of water molecules to hydrogen and oxygen. This part of the reaction, however, represents only half of the overall process needed for hydrogen generation.

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.

New photoelectrode with enhanced visible light absorption for improved solar water-splitting for hydrogen production

Green Car Congress

A team of researchers at Ulsan National Institute of Science and Technology (UNIST), Korea University, and the Korea Advanced Institute of Science and Technology (KAIST) has developed a new type of multilayered (Au NPs/TiO 2 /Au) photoelectrode that could boost the ability of solar water-splitting to produce hydrogen.

Researchers develop efficient single-atom Ni catalyst for conversion of CO2 to CO

Green Car Congress

While Ni metal catalyzes the hydrogen evolution reaction (HER) exclusively under CO 2 RR conditions, Ni single atomic sites present a high CO selectivity of 95% under an overpotential of 550 mV in water, and an excellent stability over 20 hours’ continuous electrolysis. The current density can be scaled up to more than 50 mA cm?2

Researchers at UC Santa Barbara develop efficient and stable plasmonic water splitter; potential alternative to semiconductor-based solar conversion

Green Car Congress

Researchers at UC Santa Barbara have developed an efficient, autonomous solar water-splitting device based on a gold nanorod array in which essentially all charge carriers involved in the oxidation and reduction steps arise from the hot electrons resulting from the excitation of surface plasmons in the nanostructured gold (plasmonic water-splitter).

New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. In part of the visible spectrum (400–485?nm), in neutral (pH?~?7.0) Chowdhury et al.
