Kobe team’s hematite mesocrystal photocatalyst simultaneously produces hydrogen and hydrogen peroxide

Green Car Congress

Ideally, photocatalysts could use sunlight and water to produce hydrogen, however it is necessary to achieve a conversion rate of 10% to enable such a system to be adopted industrially. It has been pointed out that even if this efficiency is achieved, the cost of hydrogen will not reach the desired value. under 600nm). Tachikawa et al.

Lux Research: cost of electrofuels remains far from viable

Green Car Congress

Production costs per barrel of oil equivalent. The cost of electrofuels—fuels produced by catalyst-based systems for light capture, water electrolysis, and catalytic conversion of carbon dioxide and hydrogen to liquid fuels—remains far away from viable, according to a new analysis by Lux Research.

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.

University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. Different sources of light were used, ranging from a laser to white light simulating the solar spectrum.

showed for the first time how MEG allowed a solar cell to exceed 100% quantum efficiency by producing more electrons in the electrical current than the amount of photons entering the solar cell. Light is absorbed at the photoanode within the QD layer producing free electrons and holes. —Matthew Beard. Nozik, Matthew C.
