(PhysOrg.com) -- Three dimensions are not necessarily better than two. Not where ceria is concerned, in any case. Ceria is an important catalyst. Because of its outstanding ability to store oxygen and release it, ceria is primarily used in oxidation reactions. Christopher B. Murray and a team at the University of Pennsylvania have now developed a simple synthetic technique to produce ceria in the form of nanoplates. As the researchers report in the journal Angewandte Chemie, these have proven to be better at storing oxygen than conventional three-dimensional nanoparticles.
