Titanium dioxide (TiO2) films, because of their special properties, have been studied extensively as semiconductor photocatalyst for solar energy conversion and purification of water and air. Plasma CVD is highly efficient for depositing TiO2 films, but it has mainly been low pressure incorporated with sophisticated discharge and vacuum systems that have been adopted. Thus, in recent years, atmospheric-pressure...
Supported gold (Au) nanocatalysts have attracted much attention due to their high activities in CO oxidation at low-temperature. While the deactivation of gold catalysts during the reaction limits their practical use. Two major reasons for the deactivation were put forward and accepted in general, i.e. agglomeration of gold particles and accumulation of carbonate-like species1,2. The agglomeration...
