Duke team develops new core-shell copper nanowire catalyst for efficient water oxidation for solar fuels

Green Car Congress

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. Chen et al. Click to enlarge. A team led by Benjamin J.

New Efficient Iron Catalyst for Water Oxidation

Green Car Congress

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.

Nanobox strategy to improve performance of Li-S batteries

Green Car Congress

Researchers at Changchun University of Science and Technology in China have developed a nanobox strategy to improve the performance of lithium-sulfur batteries. The ZIF-67 nanocubes were dispersed in a mixed solution containing ethanol (20 mL) and deionized water (5 mL). A paper on their work appears in the Journal of Power Sources.

Cambridge team demonstrates light-driven photoreforming of unprocessed biomass to H2 at room temperature

Green Car Congress

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. The catalytic nanoparticles were added to alkaline water in which the biomass was suspended. Wakerley, Moritz F.
