Network Structured CuWO4/BiVO4/Co-Pi Nanocomposite for Solar Water Splitting

Solar water splitting cells.

Energy harvested directly from sunlight offers a desirable approach toward fulfilling, with minimal environmental impact, the need for clean energy. Solar energy is a decentralized and inexhaustible natural resource, with the magnitude of the available solar power striking the earth’s surface at any one instant equal to 130 million 500 MW power plants.1 However, several important goals need to ...

Electrodeposited Co-Pi Catalyst on α-Fe2O3 Photoanode for Water-Splitting Applications

Optoelectronic properties of hematite (α-Fe2O3) as a photoanode and the required over-potential in photo-assisted water splitting has been improved by presence of Co-Pi on its surface. In order to increase the lifetime of the photogenerated holes and lower the applied bias, cobalt-phosphate (Co-Pi) on nanostructured α-Fe2O3 by electrodeposition was de...

Identifying champion nanostructures for solar water-splitting.

Charge transport in nanoparticle-based materials underlies many emerging energy-conversion technologies, yet assessing the impact of nanometre-scale structure on charge transport across micrometre-scale distances remains a challenge. Here we develop an approach for correlating the spatial distribution of crystalline and current-carrying domains in entire nanoparticle aggregates. We apply this a...

Water Splitting: One‐dimensional TiO2 Nanotube Photocatalysts for Solar Water Splitting (Adv. Sci. 1/2017)

Shining a light on solar water splitting.

www.sciencemag.org SCIENCE VOL 344 2 MAY 2014 COVER A blood star (Henricia leviuscula) near Whidbey Island, Washington state. It is one of 10 species of sea star that appear to be affected by a mysterious wasting syndrome on the west and east coasts of North America. Various levels of mortality have been confi rmed in 10 other species, making this the largest documented die-off of echinoderms. ...
