Abstract

Photocatalysis of the mixture of rhodamine-B and Cr (VI) by activated natural zeolite (ZA) loaded TiO2 and ZnO semiconductor materials has been carried out. This study aims to determine the ability of ZA-TiO2/ZnO photocatalyst in degradation of rhodamine-B and reduction of Cr (VI) simultaneously under the visible light irradiation. The photocatalyst is synthesized using the ceramic method. The photocatalyst is analyzed to determine the success of the synthesis process, namely functional groups analyzed by infrared spectrophotometer (FTIR) and surface acidity by acid-alkalimetry titration method. The analysis result of the functional groups of ZA-TiO2/ZnO photocatalyst showed that the specific peaks of Ti-O appeared at wavenumbers of 2368.69 cm-1 and 678.11 cm-1 as well as the peaks of Zn-O appeared at 884.4 cm-1, 501.01 cm-1 and 438.46 cm-1. The peaks of O-Si-O and O-Al-O bonds in the aluminosilicate of zeolite framework were appeared at 788.91 cm-1 and 1055.1 cm-1. In addition, the active sites tend to be acidic with the number of active sites was 16.9515 x 1020 sites/g. The photocatalytic process showed that the highest value of degradation of rhodamine-B and reduction of Cr (VI) simultaneously at pH 3, with an irradiation time of 10 minutes and a photocatalyst mass of 300 mg, which reached 99.91% and 99.92%, respectively. The photocatalyst activity of ZA-TiO2/ZnO for rhodamine-B degradation and Cr (VI) reduction simultaneously under the visible light irradiation, so that it is important considered.
