Slow Photon Enhanced Photocatalytic Activity of ZnO Inverse Opal Film Synthesized by Sol-gel Method

International Conference on Nanoscience & technology,China 2013(ChinaNANO 2013)

Recently, inverse opal structures, which have many potential applications in catalysts, separations, sensors, bioscience and photonics for their unique advantages such as highly ordered pore structure, large specific surface areas. The common synthesis strategy for inverse opal films is colloidal crystal templating method. This method included three steps: (1) synthesizing the hexagonal ordered-closed colloidal crystals;(2) immersing the liquid mental precursor into the voids of the templates;(3) removing the templates by calcination or etching. Several fabrication methods for ZnO inverse opal film synthesis have been reported including atomic layer deposition, chemical vapor deposition and electrodeposition. However the large-scale ZnO inverse opal film synthesized by sol-gel method has seldom been reported and the mechanism on the photocatalytic activity of ZnO inverse opal film is still needed to be explored. In this work, different sizes of P(St-MMA-SPMAP) colloidal spheres were used as templates and Zn(NO 3 ) 2 as precursor to obtain the ZnO inverse opal film. The products have been characterized by XRD, SEM, and UV/Vise spectrometer. The morphology of the products is highly organized, dense and large-scale and the crystalline of the products is hexagonal wurtzite structure. The different sizes of ZnO inverse opal films have been applied for the photodecomposition of the rhodamine B (RhB) in water. Through the results it can be concluded that the photocatalytic activity has been correlated with the pore sizes of the ZnO inverse opal film, which ascribe to the slow photon effect. When the stop-band edge matches the irradiation wavelength, it can increase the path length of light by enhancing the light absorption of the material resulting in enhanced photocatalytic activity.

Electromagnetic parameters and microwave-absorption properties for the mixtures of mechanically milled spherical and flaky carbonyl iron powders

Acta Metallurgica Sinica(English Letters) 2012年第3期25卷 201-206页

The electromagnetic parameters were measured for the mixtures of mechanical milled carbonyl iron powders （CIPs） with different mass ratios of spheroid-like particles to flake-shape particles. The results indicate that mixing the sphere-like CIP particles with flake-shaped CIPs can be used to adjust effectively the electromagnetic parame- ters and enhance the absorption property in high frequency. In addition, a theoretic simulation based on the principle of superposition was carried out and compared with the microwave measurement results, indicating that the simple principle of superpo- sition can not reflect truly the internal interaction mechanism in the composites with different particle shapes.
