通过吸附和光催化的双重作用

甲基橙的降解率可达99%。采用X射线衍射(XRD)、扫描电子显微镜(SEM)等对复合膜进行了表征

并通过傅里叶红外光谱(FT-IR)分析表明其壳聚糖中活性官能团 NH2

OH在氮掺杂TiO2 复合膜中同时存在。研究表明

氮掺杂二氧化钛/壳聚糖(CS)复合膜是一种高效节能的污水处理材料。

Abstract

A novel N-doped TiO2/Chitosan (CS) composited film

as a promising alternative material

was prepared

and could be more potential compared with tradition materials for treating wastewater. When this material

N-doped TiO2/CS film

was used for removing Methyl Orange (MO) under simulated solar light irradiation

about 99% of total MO removal was achieved due to the combination effect of photo-degradation and adsorption processes. N-doped TiO2/CS photo-catalyst was characterized by using X-ray diffraction (XRD)

scanning electron microscopy (SEM)

and Fourier transform infrared spectroscopy (FT-IR) analysis. The results indicate that there exist the reactive groups NH2

OH on the N-doped TiO2 film

and their contents in the prepared photo-catalyst are responsible for the photo-degradation and adsorption effect

which was confirmed by FT-IR. Hence

it is possible that using N-doped TiO2/ CS film as a simple method for removal of the pollutants in wastewater.
