Nitrogen physical adsorption was carried out on Quantachrome Autosorb Automated Gas Sorption System. Scanning electron microscopy (SEM) investigations were performed using a QUANTA 200 scanning electron microscope. Fourier transform infrared (FTIR) spectra were recorded in ATR mode on Bruker Vertex 70 model FTIR instrument. The X-ray diffraction analyses were conducted on a Bruker AD8 Advance XRD diffractometer operating at Cu Kα radiation. The water contact angle was measured using Conrad USB digital microscope and ImageJ software.
