Hydrothermal synthesis of Ag2MoO4 with photocatalytic activity for rhodamine B degradation

Hydrothermal synthesis of Ag2MoO4 with photocatalytic activity for rhodamine B degradation The cubic Ag2MoO4 photocatalyst was prepared with a solvothermal method using ethanol as a solvent. The morphology and structure of the obtained materials were analyzed by using X-ray diffraction and transmission electron microscopy. The effect of different heat treatment conditions on the visible-light response of Ag2MoO4 was studied by UV-Vis spectroscopy. The obtained Ag2MoO4 materials were applied as photocatalysts for the degradation of rhodamine B (RhB), and the degradation process was analyzed by using Fourier transform infrared spectroscopy (FTIR). The material synthesized at 100 °C for 12 h exhibited the best photocatalytic activity, with degradation of RhB reaching 95.0% within 60 min. The RhB degradation process had a short half-life and an average activation energy of 32.7 kJ/mol. The results of the photocatalytic experiments were in good agreement with the material characterization results. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of the Australian Ceramic Society Springer Journals

Abstract

The cubic Ag2MoO4 photocatalyst was prepared with a solvothermal method using ethanol as a solvent. The morphology and structure of the obtained materials were analyzed by using X-ray diffraction and transmission electron microscopy. The effect of different heat treatment conditions on the visible-light response of Ag2MoO4 was studied by UV-Vis spectroscopy. The obtained Ag2MoO4 materials were applied as photocatalysts for the degradation of rhodamine B (RhB), and the degradation process was analyzed by using Fourier transform infrared spectroscopy (FTIR). The material synthesized at 100 °C for 12 h exhibited the best photocatalytic activity, with degradation of RhB reaching 95.0% within 60 min. The RhB degradation process had a short half-life and an average activation energy of 32.7 kJ/mol. The results of the photocatalytic experiments were in good agreement with the material characterization results.
