Abstract :
High Cross-linked TiO2-SiO2 Composite Material was prepared via Sol-gel Process under chelation by diethanolamine. Sample TS01 was of the anatase phase by XRD. In contrast to TS00, the high cross-linked TiO2 photocatalyst could more readily photodegrade methylene blue (MB) under UV-light irradiation. The UV-light catalytic activity of thus-prepared photocatalyst resulted from the high cross-linked structure which reduced electron-hole recombination rate.
