07-26-2010: Only a single metal centre is needed to catalyse the reduction of oxygen to produce water, according to researchers in the US.
Daniel Nocera and colleagues at Massachusetts Institute of Technology have shown for the first time that single centre cobalt porphyrins anchored on carbon nanotubes and containing a proton transfer group efficiently catalyse the reduction of oxygen. It could open the door to more efficient fuel cells in the future.
Reducing oxygen to water is a key reaction involved in releasing stored energy from hydrogen fuel cells which has previously required expensive bimetallic catalysts. Nocera’s porphyrins are more efficient than existing cobalt catalysts and are made easily in two steps, so could invigorate the design of future fuel cells using cobalt over its more costly metal cousins.

The world's fastest camera: Trillion-frame-per-second video
MIT researchers have created a new imaging system that can acquire visual data at a rate of one trillion exposures per second. That’s fast enough to produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bo ... more
MIT research update: New way to store sun's heat
A novel application of carbon nanotubes, developed by MIT researchers, shows promise as an innovative approach to storing solar energy for use whenever it's needed.Storing the sun's heat in chemical form — rather than converting it to electricity or storing the heat itself in a heavily insu ... more
MIT Study: conventional fossil fuels sometimes 'greener' than biofuels
In an effort to combat soaring fuel prices and cut greenhouse gas emissions, the aviation industry is racing toward the use of biofuels. In 2008, Virgin Atlantic became the first commercial airline to fly a plane on a blend of biofuel and petroleum. Since then, Air New Zealand, Qatar Airway ... more
