Single nanocatalyst behaviour revealed

Abstract:
Before you can design the perfect nanoparticle catalyst, you first need to understand the fundamental science that governs their reactivity, say scientists from the US. And they claim to have done just that, using single molecule spectroscopy to reveal that nanocatalyst surface properties respond to changes to the concentration of reactants.

The team led by Peng Chen at Cornell University, Ithaca, have devised a technique for studying the catalytic properties of individual gold nanoparticles - which gets around the traditional problem with studying nanocatalysts, says Chen. 'No matter how good a synthetic chemist you are, the nanoparticles you make will have slightly different sizes and shapes, and this is why you need to study one particle at a time, so you don't have to average all of them.'
