Title
Ammonium oxidization at room temperature and plasmonic photocatalytic enhancement
Abstract

In an alkaline condition, ammonium can be efficiently reduced with hydroxide ion using a spinning disk reactor at room temperature. To some extent, illumination can boost the processing efficiency by warming water. A homogeneous 8 nm crystallized platinum thin film deposited on a B270-glass substrate by plasma-enhanced atomic layer deposition absorbs light from 350 nm to 2500 nm. The absorbed light transforms plasmonic resonance energy on the platinum thin film and forms a high temperature hot layer. The plasmonic heating effect, or plasmonic photocatalytic reaction, enhances the activity of the Pt thin film for the oxidation of NH4+.
