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 ?

Bio-inspired molybdenum sulfide catalyst offers low-cost and efficient photo-electrochemical water splitting to produce hydrogen

Green Car Congress

The optimized photo-electrochemical water splitting device uses light absorbers made of silicon arranged in closely packed pillars, dotted with tiny clusters of the new molybdenum sulfide catalyst. An alternative, clean method is to make hydrogen fuel from sunlight and water via a photo-electrochemical (PEC, or water-splitting) process.

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

A Northwestern Engineering-led team has developed a highly porous smart sponge that selectively soaks up oil in water. With an ability to absorb more than 30 times its weight in oil, the sponge could be used to clean up oil spills inexpensively and efficiently without harming marine life. —Vikas Nandwana.

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.

Japan team reports pathway to green ammonia: photocatalytic conversion of nitrogen with water

Green Car Congress

Researchers in Japan report that a commercially available TiO 2 with a large number of surface oxygen vacancies, when photo-irradiated by UV light in pure water with nitrogen—successfully produces ammonia (NH 3 ). As a result of this, NH 3 is produced from water and N 2 under ambient conditions by using sunlight as energy source.
