An examination has been conducted of the effect of sonication time (25 kHz) at a constant temperature of 25°C on the structure of hydroxyapatite (HAp). Diammonium hydrogen phosphate and calcium nitrate tetrahydrate were used as starting materials. The gel formed by mixing the starting materials solution was subjected to sonication for 0, 5, 10, 20, 30 and 40 min. After sonication, HAp was dried at...
A Cu2+-doped 2, 4-dichlorophenol (2, 4-DCP) molecularly imprinted TiO2-SiO2 nanocomposite catalyst was prepared by molecular imprinting technique in combination with sol-gel methods. The prepared material was characterised by X-ray diffraction (XRD), infrared spectroscopy (IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and N2 adsorption measurements. The photocatalytic...
