概要 |
In this paper, the kinetics of photoinduced degradation of rhodamine B (RhB) in aqueous solution utilizing synthesized copper oxide (CuO) particles as catalyst has been studied by measuring the absorb...ance of the dyes at various time intervals. The CuO particles were fabricated using sol-gel method, and calcined at different temperatures in the range from 450 to 750 °C. The crystallinity of the CuO particles was confirmed using powder X-ray diffraction. The highest RhB degradation efficiency was only 10.9% by the CuO550 upon UV irradiation in 30 min, proving that CuO particles, regardless of their calcination temperature, showed poor photodegradation activity.続きを見る
