hydrogen

David Kilper/WUSTL PhotoPratim Biswas and his group have developed a method to make a variety of oxide semiconductors that, when put into water promote chemical reactions that split water into hydrogen and oxygen.Engineers at Washington University in St. Louis have developed a unique photocatalytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. The group is developing novel methodologies for synthesis of nanostructured films with superior opto-electronic properties.

WUSTL engineers have developed a unique photocatlytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. The technique will be demonstrated at a poster session May 6, 2007, at the International Symposium on Energy and Environment, held at the University.

That’s a lot of power potential from microscopic cyanobacteria (blue-green algae) that capture sunlight and then do a variety of biochemical processes. One potential process, the clean production of ethanol, is a high priority for DOE. Himadri Pakrasi, Ph.D., Washington University Professor of Biology in Arts & Sciences, and Professor of Energy in the School of Engineering and Applied Science, will head a team of biologists at Washington University and elsewhere in the analysis of the genomes of six related strains of Cyanothece bacteria.

Storing hydrogen is problematic. A WUSTL chemist and his colleagues are exploring different approaches to help make hydrogen fuel more practical.A chemist at Washington University in St. Louis hopes to find the right stuff to put the element hydrogen in a sticky situation. Lev Gelb is exploring several different ways to store hydrogen and prepares theoretical models of molecules that could enable storage and transport of hydrogen gas. One process would involve materials that hydrogen would stick to.
