Zhang, Kaiyue; Lu, Guilong; Chu, Feng; Huang, Xiubing published the artcile< Au/TiO2 nanobelts: thermal enhancement vs. plasmon enhancement for visible-light-driven photocatalytic selective oxidation of amines into imines>, Recommanded Product: 4-Bromobenzylamine, the main research area is mixed phase titanium dioxide nanobelt preparation; Au loaded titanium dioxide preparation; imine selective preparation; amine oxidation titanium dioxide nanocatalyst.
Herein, photocatalytic selective aerobic oxidation of amines to imines RCH2N=CHR1 [R = R1 = Ph, 2-BrC6H4, 3-pyridyl, etc.] was investigated under visible light irradiation over heterostructured TiO2(B)/anatase and Au/TiO2 nanobelts at specific temperatures (20-60°C). The surface amine substrate complexed on TiO2 could broaden the visible-light absorption region via the ligand-to-metal charge transfer (LMCT) effect. Interestingly, the pristine TiO2 achieved the best photocatalytic performance (>99% benzylamine conversion and >99% N-benzylidenebenzylamine selectivity) at 60°C after 12 h irradiation while the Au nanoparticles (NPs) were observed to improve the activity of TiO2 only in a low temperature range (<40°C). Moreover, excessive Au NPs loaded on TiO2 could inhibited the amine conversion and reduced the imine selectivity in the whole temperature range of 20-60°C, which was attributed to the decreased oxygen vacancies and poor amine adsorption ability on the surface of Au/TiO2.
