Mechanical Coating Technique for Composite Films and Composite Photocatalyst Films

A novel TiO2/Cu composite photocatalyst thin film was successfully fabricated by 2-step Mechanical Coating Technique (2-step MCT). The composite photocatalyst thin film was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), among others. The formation process of Cu thin film and TiO2/Cu composite photocatalyst thin film were also examined. The results revealed that the formation of Cu thin film can fall into the following stages: nucleation, growth of nuclei and connection, formation and thickening of continuous thin film, and the exfoliation of thin film. In addition, TiO2/Cu composite thin film had a composite microstructure of TiO2islands coated on Cu thin film. Furthermore, the photocatalytic activity of TiO2/Cu composite photocatalyst thin film was evaluated by measuring the degradation rate of methylene blue (MB). Enhancement on the photocatalytic activity of TiO2was confirmed. The improvement of the photocatalytic activity of TiO2/Cu composite photocatalyst thin film should result from the increase of the charge separation efficiency and the mass increase of TiO2in the composite thin film.

Mechanical Coating

In the present work, 2-step mechanical coating technique (2-step MCT), an advanced MCT, was proposed and carried out to form TiO2/Ti composite photocatalyst film with anatase TiO2. The microstructures and photocatalytic activity of the composite film were investigated. The results show that the proposed 2-step MCT is a simple process for forming TiO2/Ti composite film. The composite film has a microstructure with a nonuniform thickness, like random distribution islands. The TiO2/Ti composite film has high photocatalytic activity, which is related with crystallinity and volume of the TiO2 in the composite film.

Mechanical Coating

The influence of intermittent air introduction on the formation of Zn films during mechanical coating process was investigated. A series of contrast experiments were carried out. The XRD and EDS results showed that Zn particles were slightly oxidized. The SEM images indicated that disk-like zinc oxide (ZnO) nanocrystals were formed. The formation of disk-like ZnO made the morphology of Zn films more uneven and irregular. On the other hand, it increased the adhesion strength of Zn films to Al2O3 balls and hence the exfoliation of Zn films was not found.
