Abstract

There are variety of technique that being used for water treatment but photocatalytic activity is one of the most efficient and low cost method. In this paper, photocatalytic properties of nanostructures cupric oxide (CuO) has been investigated. CuO has a norrow bandgap energy of 1.2 eV. The nanostructures CuO were synthesized via dip coating method and characterized by field emission scanning electron microscopy (FESEM) to observed the surface morphology of the films. Photocatalytic experiments was carried out on sample of 60 cycles with 200 °C, 300 °C and 400 °C of annealing temperature due to their highest density and homogenous distributed on the substrate. Every sample have been exposed to solar simulator for 2.5 hours. Photocatalytic property was examined using ultraviolet-vis (UV-vis) spectrophotometer. The results showed that higher annealing temperature as well as longer exposured duration to the solar simulator exhibits enhanced photocatalytic performance.

浸涂法制备CuO纳米结构及其增强光催化性能

目前用于水处理的技术有很多种，但光催化活性法是最有效、成本最低的方法之一。本文研究了纳米结构氧化铜(CuO)的光催化性能。CuO具有1.2 eV的窄带隙能量。采用浸涂法制备了CuO纳米结构，并用场发射扫描电镜(FESEM)观察了薄膜的表面形貌。在200°C、300°C和400°C的退火温度下，对60次循环的样品进行光催化实验，因为它们的密度最高，在衬底上分布均匀。每个样品在太阳模拟器中暴露2.5小时。用紫外-可见分光光度计测定了其光催化性能。结果表明，较高的退火温度和较长的太阳模拟器暴露时间可以增强光催化性能。
