Two different mesoporous silica structures (hexagonal and lamellar) were synthesized via sol-gel method
using a series of triblock copolymer (Pluronic) surfactants. L81, L61 & L31 surfactants form lamellar structure
whereas P123 surfactant forms a hexagonal structure. CuO and ZnO nanoparticles (NPs) supported
mesoporous silica were synthesized using impregnation method. The structural properties of these materials
were investigated using several characterization techniques such as FTIR, XRD, SAXS, TEM and TGA.
SAXS and TEM confirmed that the obtained mesoporous silica is based on the EO/PO ratio of Pluronic surfactants.
They proved that the mesoporosity of silica is well maintained even after they loaded with metal
oxide nanoparticles.
