Abstract:

Aldehydes and esters have been widely used as additives in daily chemicals due to the characteristics of sterilization, antisepsis and long-lasting aroma. The selective oxidation of alcohols to aldehydes and esters can achieve low-toxic, green and pollution-free synthetic routes. The LSPR metal catalysts are widely used as excellent catalysts for the oxidation of alcohols. Herein, the catalytic mechanism of LSPR metal-catalyzed oxidation of alcohols to aldehydes and esters are summarized, as well as the applications in the field of daily chemicals. The LSPR metals of Au, Ag and Cu are used as the active centers, which display high catalytic activity for the oxidation of alcohols, and the high selectivity to aldehydes and esters can also be obtained. In addition, the catalytic mechanism of LSPR metals under light conditions and the advances of photocatalytic selective oxidation of alcohols are reviewed based on the LSPR effects of the three metals, which can generate a large number of hot electrons on the surface of metals under light conditions. The oxidation of alcohols to aldehydes and esters can be promoted by the hot electrons. Besides, the reaction not only can be carried out under milder conditions, but also be more selective to the aldehydes and esters. In addition, the application of aldehydes and esters in daily chemical field are summarized. It is found that the aldehydes and esters prepared by the oxidation of alcohols as catalyzed by LSPR metals can achieve comparatively practical value in daily chemical field.
