Photocatalytic activity of the modified composite photocatalyst by introducing the rich-nitrogen complex to the Bi2WO6

• 1,4-bis(bis(3,5-dimethyl-1H-pyrazol-1-yl)methyl)benzene
• Preparation and characterization of the cadmium complex containing N-heterocycle and azide
• Photocatalytic activity and mechanism of the Bi2WO6 composite with the N-heterocycle and azide complex

A metal–organic complex [Cd2(L)(N3)4]·DMF was prepared by the reaction of Cd(NO3)2·4H2O, NaN3 and ligand L (L: 1,4-bis(bis(3,5-dimethyl-1H-pyrazol-1-yl)methyl)benzene) in a DMF system. And the complex was characterized by elemental analysis, IR spectroscopy, UV–vis spectroscopy, thermal gravimetric technology, X-ray powder diffraction and single-crystal X-ray diffraction. Furthermore, the complex was combined with Bi2WO6 to form a composite, which was used as photocatalyst to degrade the basic dye methylene blue (MB) under the Xe lamp irradiation. The result revealed that the photocatalytic activity of the composite was better than that of the pure Bi2WO6 and the complex. In addition, the mechanism of the photocatalysis was also studied.
