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 ?

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.

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.

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.

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.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. Earlier post.). simulated sunlight. constructing a simple, stand-alone device composed of.

BNL Researchers develop low-cost, efficient, non-noble metal electrocatalyst to produce hydrogen from water

Green Car Congress

James Muckerman at the US Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have developed a new class of high-activity, low-cost, non-noble metal electrocatalyst that generates hydrogen gas from water. The result becomes this well-balanced Goldilocks compound—just right. —James Muckerman.
