Publication date: 25 July 2018Source: Journal of Industrial and Engineering Chemistry, Volume 63Author(s): Seung Hwa Yoo, Sung-In Lee, Han-Ik Joh, Sungho LeeAbstractA highly effective photocatalyst based on CdSe quantum dots (QDs) and TiO2 nanoparticles well-dispersed on carbon nanofibers (CNFs), named as CdSe/TiO2/CNF was synthesized by simple successive ionic layer adsorption and reaction (SILAR) method on TiO2/CNF. It was verified by spectroscopic analysis that CdSe QDs were successfully synthesized and some aggregations and oxide phases existed in CdSe/TiO2/CNF. The photocatalytic activity of CdSe/TiO2/CNF was demonstrated for decomposition of methylene (MB) aqueous solutions. The tests were performed for different MB concentrations and light irradiation. It was found that CdSe/TiO2/CNF showed high photocatalytic activity under visible light irradiation and even high MB concentrations.Graphical abstract
