Green Sol–Gel Synthesis and Comprehensive Characterization of Mesoporous Silica Nanoparticles (MSN)

Mesoporous silica nanoparticles (MSN) have a wide range of potential applications, making the creation of effective and environmentally friendly processes for their production essential. MSN with improved characteristics were created in this work using a green sol–gel synthesis technique. Infrared spectroscopy, X-ray diffraction, and other analytical methods were used to analyze the synthesized MSN. The XRD examination supported the crystalline structure of MSN nanoparticles and assigned peaks to the (122), (111), (201), (223), and (313) crystal planes. The MSN surface was found to include a number of functional groups, according to the FTIR study. The development of MSN was visible in SEM and pictures, with particle sizes ranging from 50 to 80 nm with a predominance of spherical shape. The conformation of MSN was found from the BET analysis with a pore size of 11.23 nm. The MSN produced using this green sol–gel method also displayed improved qualities like a high surface area, a large pore volume, and superior thermal stability. The results show that the sol–gel process has the potential to be an effective and environmentally friendly way to create MSN nanoparticles with improved characteristics for a variety of applications.
