Abstract:In this work, a facile and low-cost method for fabrication of the Fe3O4/chitosan/TiO2 nanocomposites with good adsorptive, photocatalytic, regenerated and magnetic properties was demonstrated. The synthesized nanocomposites had potential applications for the adsorption and degradation of organic pollutants in wastewater. Under the optimal condition, degradation rate of the methyl blue by the Fe3O4/chitosan/TiO2 nanocomposites was 93%. The renewable photocatalytic activity of the nanocomposites was also investigated. After multi-run experiments, the reused Fe3O4/chitosan/TiO2 nanocomposites still kept high photocatalytic performance. Thus, Fe3O4/chitosan/TiO2 nanocomposites could serve as convenient, effective, and recyclable photocatalysts. | |||

Abstract:A novel method was achieved for directed aligning high organized single-walled carbon nanotubes (SWNTs) over large areas using a template-based fluidic assembly process. Lithographically patterned Polydimethylsiloxane (PDMS) template was used to guide the fluidic self-assembly of SWNTs on SiO2/Si substrates. The electrical characteristics of the assembled nanotubes were investigated. In our work, the field effect transistors (FET) were P-type with an On/Off ratio of 106. The developed alignment process was propitious to build SWNTs-based electronics in a large scale with high sensitivity, little response time and wide temperature range. The concentration and length of SWNTs suspension, the width and shape of PDMS channels were also discussed. | |||
