UNIST team develops novel hydrogen production process using biomass oxidation instead of water oxidation as electron source

Green Car Congress

Korea’s Ulsan National Institute of Science and Technology (UNIST) have developed a novel process for the production of hydrogen using various types of biomass, including lignin, as an efficient alternative to water oxidation as an electron source. Conventionally, water is considered a cheap and clean source of electrons; 2H 2 O ?

Efficient recovery of lithium from spent LiFePO4 batteries via air oxidation–water leaching at room temperature

Green Car Congress

Researchers in China report using air oxidation–water leaching to recover lithium selectively from spent LiFePO 4 (LFP) material, in which the high leaching efficiency of lithium and the good separation effect of lithium and iron were achieved simultaneously. An open-access paper on their work is published in the RSC journal Green Chemistry.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. The researchers believe this new type of photoelectrode is not only cheap to produce, but can also be recreated on a larger scale for mass and worldwide use.

New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. Photosynthesis is the process by which chloroplasts in plants and some organisms use sunlight, water and carbon dioxide to create food or energy.

ICL researchers develop new membrane-based system for cheap, efficiently made biofuels

Green Car Congress

Researchers at Imperial College London have developed a membrane-based extraction system for the production of biofuels which uses less than 25% of the energy of current processes and produces ten times more biofuel with more than 99.5% The open-access findings are published in the RSC journal Energy & Environmental Science.

Researchers split seawater without pre-treatment to produce green hydrogen

Green Car Congress

The use of vast amounts of high-purity water for hydrogen production may aggravate the shortage of freshwater resources. This is achieved by introducing a Lewis acid layer (for example, Cr 2 O 3 ) on transition metal oxide catalysts to dynamically split water molecules and capture hydroxyl anions.

KAUST team alters atomic composition of MoS2 to boost performance as water-splitting catalyst for H2 production

Green Car Congress

Researchers at KAUST have developed and used a novel way of increasing the chemical reactivity of a two-dimensional molybdenum disulfide material to produce a cheap and effective catalyst for water splitting to produce hydrogen. A monolayer of molybdenum disulfide is only reactive for reducing water to hydrogen at its edge.
