Geopolymer-TiO2 nanocomposites were prepared by two different techniques, namely the two-step acidification calcination treatment and one-step adding method. The potential photocatalytic activities of geopolymer-TiO2 nanocomposites prepared by the two different methods were tested and compared. Nanocomposites prepared via the one-step process showed better photocatalytic activity. The amount of TiO2 particles loaded on the surface of the foaming materials was investigated by XRD and SEM-Mapping. By comparing with the sample obtained from two-step treatment, the TiO2 particles were distributed uniformly on the surface of the foaming materials for the sample obtained from the one-step method in this study. Results showed that the specific surface area of the geopolymer-TiO2 prepared by the one-step treatment process (28.67 m2/g) was significantly lower than the two-step acidification calcination process (215.04 m2/g), while the photocatalytic efficiency with methylene blue trihydrate (MB) was better. This is due to the more stable structure of geopolymer-TiO2 nanocomposites, the better dispersion and more loading of TiO2 particles on the foaming materials surfaces, leading to the enhanced photocatalytic activity.

In this work, a novel photocatalyst with excellent photocatalytic activities was developed by the combination of TiO2 with graphene oxide (GO). GO was firstly prepared by the chemical oxidation of graphite through Hummers method and the subsequent dispersion and exfoliation in water. Then, GO and P25 nanoparticles (commercial TiO2) were used as raw materials to synthesize TiO2/graphene (TiO2/GE) nanocomposites by using a one-step solvothermal method. TEM images clearly showed that TiO2 nanomaterials (the size of about 15~20 nm) were distributed well onto the two-dimensional (2D) graphene sheets, indicating the formation of TiO2/GE nanocomposites. XRD results indicated that TiO2/GE nanocomposites exhibited TiO2 crystalline phase structure. Meanwhile, it was demonstrated from the methylene blue (MB) photodegradation results that TiO2/GE nanocomposites possessed excellent photocatalytic activities with potential applications.

Ag-modified CaBiO2Cl photocatalysts were synthesized by the one-step solid state reaction method. The microstructure and morphology of catalysts were characterized by using X-ray diffraction, Scanning electron microscopy, and Energy dispersive X-ray detector (EDS) techniques. The photocatalytic activities of pure CaBiO2Cl and Ag-CaBiO2Cl catalysts were further evaluated by degrading methylene blue (MB) under visible-light irradiation. The measured UV-vis absorption spectra indicated that the degradation of Ag-modified CaBiO2Cl has been improved by about 12% in comparison with pure CaBiO2Cl. The enhanced photocatalytic activity in Ag-modified CaBiO2Cl can be ascribed to the better morphologies of the composites due to the Ag additive.
