Photocatalytic degradation of methylene blue dye using fabricated Cu doped SiO2 nanocrystals by sol-gel method
Copper doped silica (Cu doped SiO2) nanocrystals was synthesized by one phase essential, practical, cost effective and quick precipitation strategy using sodium silicate (Na2SiO3) where copper sulfate (CuSO4.5H2O) as precursors and acetic acid (CH3COOH) as a catalyst. The boundaries tried in this analysis are the impact of sintering temperature via microwave oven and the properties of the synthesized Cu doped SiO2 nanocrystals. The motivation behind this study was to acquire a crystalline Cu doped SiO2 material, which is in nano-sized dimension. The characterisation was performed by utilizing X-ray diffraction (XRD), Fourier transmission infrared (FTIR), scanning electron microscopy-energy dispersive spectrometer (SEM-EDS), UV-visible spectroscopy and TG-DSC. Furthermore, the photocatalytic activities of the synthesized nanocrystal were investigated as photocatalyst against methylene blue (MB) dye under UV irradiation.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
