Can Cobalt-Graphene Beat Out Platinum As Catalyst in Hydrogen Fuel Cells?

Platinum works well as a catalyst in hydrogen fuel cells, but it is expensive and degrades over time. Brown University chemist Shouheng Sun and his students have developed a new material — a graphene sheet covered by cobalt and cobalt-oxide nanoparticles — that can catalyze the oxygen reduction reaction nearly as well as platinum does and is substantially more durable.

Promoting Virtual Power Plants for Efficient Renewable Energy Production

Researchers from the School of Electronics and Computer Science (ECS) at the University of Southampton have devised a novel method for forming virtual power plants (VPPs) to provide renewable energy production in the UK. Small and distributed energy resources (DERs), such as wind farms and solar panels, have been appearing in greater numbers in the electricity supply network (Grid).

Carbon Nanotubes Help Energize Fuel Cells and Metal-Air Batteries

Fuel cells, which use chemicals to create electricity, hold promise in a variety of areas but the high price of platinum catalysts used inside the cells has provided a roadblock. One promising low-cost alternative to platinum is the carbon nanotube – an excellent conductor of electricity. Multi-walled carbon nanotubes riddled with defects and impurities on the outside could eventually replace some of the platinum catalysts used in fuel cells and metal-air batteries, according to Stanford University scientists.

Detecting Contaminants in Water

Many organic contaminants in the air and in drinking water need to be detected at very low-level concentrations. Research published by the laboratory of Prashant V. Kamat, the John A. Zahm Professor of Science at the University of Notre Dame, could be beneficial in detecting those contaminants.

New Materials May Cut Energy Costs for Carbon Capture

A study of over four million absorbent minerals has determined that industrial minerals called zeolites could help electricity producers slash as much as 30 percent of the parasitic energy costs associated with removing carbon dioxide from power plant emissions. The research was done by scientists at Rice University, UC Berkeley, Lawrence Berkeley National Laboratory, and the Electric Power Research Institute.

Technology Awarded for Improving Submarine Air Quality

Creators of a nanotech-based system that captures carbon dioxide from the atmosphere within a submarine while providing a more environmentally friendly removal process have won the Federal Laboratory Consortium Interagency Partnership Award for 2012. The technology — Self Assembled Monolayers on Mesoporous Supports, or SAMMS — is destined for incorporation into future submarines.
