• then removed and washed with deionized water several times and then dried at 70 °C for 6 h. Scanning Electron Microscopy (SEM) was carried out on a JEOL JSM-6301F SEM at an operating voltage of 20 kV. Quantitative measurements on SEM micrographs were carried out by using Scion image-processing software
