Au/TiO<sub>2</sub> nanobelts: thermal enhancement <i>vs.</i> plasmon enhancement for visible-light-driven photocatalytic selective oxidation of amines into imines
Kaiyue Zhang, Guilong Lu, Feng Chu, Xiubing Huang
Abstract
Au NPs improve the photocatalytic activity of TiO 2 only in a low temperature range. Excessive Au NPs loaded on TiO 2 inhibit the photocatalytic amine conversion due to the decreased oxygen vacancies and poor amine adsorption ability.
