Abstract

In order to utilize visible light more efficiently in the photocatalytic reaction, microspheres sensitized by 5-4-allyloxyphenyl-10,15,20-tri4-methylphenylporphyrin APTMPP were prepared and characterized by X-ray diffraction XRD, X-ray photoelectron spectroscopy XPS, nitrogen physisorption, scanning electron microscopy SEM, Fourier transform infrared spectroscopy FT-IR and UV-vis diffuse reflectance spectroscopy, and so forth, The characterization results indicated that APTMPP-MPS- was composed of the anatase crystal phase. The morphology of the composite materials was spheriform with size of 0.3–0.7 μm and the porphyrin was chemisorbed on the surface of through a Si–O–Ti bond. The photooxidation of α-terpinene was employed as the model reaction to evaluate the photocatalytic activity of APTMPP-MPS- microspheres under visible light. The results indicated that the photodegradation of α-terpinene was significantly enhanced in the presence of the APTMPP-MPS- compared with the nonmodified under visible light.
