Scientists at Tokyo Institute of Technology (Tokyo Tech) have demonstrated the first visible-light photoelectrochemical system for water splitting using TiO 2 enhanced with cobalt. The proposed approach is simple and represents a stepping stone in the quest to achieve affordable water splitting to produce hydrogen.

The Dutch Institute for Fundamental Energy Research ( DIFFER ) is partnering with Toyota Motor Europe (TME) to develop a device that absorbs water vapor, and splits it into hydrogen and oxygen directly using solar energy. This first prototype achieved 70% of the performance that is obtained when an equivalent device is filled with water.

Researchers at Carnegie Mellon University have developed a new catalyst—iron-centered tetraamido macrocyclic ligand (Fe-TAML)—that efficiently catalyzes water oxidation. Water oxidation is the second of two requisite half-reactions in the photolysis of water, the other being the reduction of protons to dihydrogen. At pH 0.7,

A transparent film of copper nanowires was transformed into an electrocatalyst for water oxidation by electrodeposition of Ni or Co onto the surface of the nanowires. Water oxidation (2H 2 O → O 2 + 4 e- + 4H + ) is a key step for converting solar energy into chemical fuels. times more light. Chen et al. Click to enlarge.

A team of scientists at the University of Cambridge has reported the light-driven photoreforming of cellulose, hemicellulose and lignin to H 2 using semiconducting cadmium sulfide quantum dots in alkaline aqueous solution. CdS is an inexpensive, visible-light-absorbing photocatalyst with a bulk electronic bandgap of around 2.4

View footage of the Toyota Mirai HFCEVs [link] Each vehicle in our light duty over-the-road fleet is driven an average of 10,000 miles per year. The zero-emissions Toyota Mirai HFCEVs have a driving range of 400 miles and since they run on hydrogen the only by-product is water.
