All the chemicals required were obtained from Sigma-Aldrich, Alfa Aesar, Spectrochem, and TCI and used without further purification. FT-IR spectra were recorded on a Bruker Alpha II system (ν max in cm−1) on KBr disks. 1H NMR and 13C NMR (400 MHz and 100 MHz respectively) spectra were recorded using a Bruker Avance II-400 spectrometer using CDCl3 as the solvent (chemical shifts in δ with TMS as internal standard). Powder XRD analyses were carried out using a Bruker D8 Advance and Rigaku Ultima IV XRD instrument. Transmission Electron Microscopy (TEM) analysis was carried out using a JEOL JSM 100CX system. Scanning electron microscopy (SEM) and Energy Dispersive X-ray (EDX) analysis were carried out using a JSM-6360 (JEOL) system. X-Ray Photoelectron Spectroscopy (XPS) was performed using a PHI 5000 VersaProbe III system. Thermogravimetric analysis (TGA) was carried out using a Perkin Elmer Precisely STA 6000 simultaneous thermal analyzer. Inductively coupled plasma optical emission spectroscopy (ICP-OES) was carried out using Thermo Scientific™ iCAP™ 7600 instrument. TLC Silica gel 60 F254 (Merck) was used for TLC analysis. Hexane refers to the fraction boiling between 60 and 80 °C.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
