One-Pot Synthesis of Bismuth Basic Nitrate-Bi2MoO6 Photocatalyst for Selective Oxidation of Toluene
文献摘要:
The key issues to improve the performance of photocatalysts for selective oxida-tion of toluene are promoting the migration and separation of charge carrier,and enhancing the generation of active oxygen species.It is known that the construction of compact hetero-junction is an efficient protocol to inhibit photogenerated electron-hole recombination.In this work,a 2D-2D[Bi6O6(OH)3](NO3)3·1.5H2O-Bi2MoO6(denoted as BBN-BMO)composite hetero-junction has been prepared by one-step hydrothermal method for the first time.The tetragonal phase BBN in the composite plays the role of transferring electrons from the visible light acti-vated orthorhombic phase BMO and promoting the generation of active·O2-the holes left in BMO are used to activate toluene and produce benzyl radical,thus greatly improving the photo-catalytic performance for selective oxidation of toluene.The toluene conversion rate of BBN-BMO is 3466 μmol g-1·h-1,which is three times that of pure BMO.The selectivity to benzalde-hyde is 94.2%.In addition,reasonable mechanism has been speculated based on a series of control experiments.
