Tungsten Trimers: A New Model for Catalysis

September 24, 2006 | Leave a Comment

Uniform Tungsten Trimers Stand and Deliver. ‘Research provides fundamental insights into catalyst structure and behavior. Like tiny nano-soldiers on parade, the cyclic tungsten trioxide clusters line up molecule-by-molecule on the titanium dioxide platform. One tungsten atom from each cluster is raised slightly, holding forth the potential to execute catalytic reactions. The nanostructures constitute a new [...]
