Studies on the Photocatalytic Decomposition of Organic Dyes Using Mesoporous Metal Oxides
Journal Title: BULETINUL INSTITUTULUI POLITEHNIC DIN IASI, CHIMIE SI INGINERIE CHIMICA - Year 2017, Vol 63, Issue 1
Abstract
In this study, the ultraviolet irradiation behaviour of three dyes (methylene blue - MB, phenol red - FR and crystal violet - CV) is presented in the presence of a mesoporous oxide material based on ZnO-CeO2. The three dyes were degraded to the corresponding leucoderivates in different times, methylene blue (conc. 10-5M) in 25 min, crystal violet (conc. 2·10-5M) in 90 min, and phenol red (conc. 4.5·10-5M) in 140 min. Also, the calculated photodegradation yield showed that MB and CV degraded by 98% and RF only by 78%. It was also investigated the influence of the photocatalyst concentration on the reaction rate for MB.
