Ag-ZSM-11 Zeolite Synthesis Using Silica from Elephant Grass for LED Application

Blog Article

Silica (SiO2) has been successfully isolated from elephant grass by the sol gel method through DANDRUFF/DRY SCALP CONDITIONER pH regulation using NaOH and HCl.The resulting silica has an amorphous character with crystalline phase impurities.The isolated silica was then used as a source of silica for the synthesis of ZSM-11 zeolite using the hydrothermal method with a ratio of SiO2 : TBAOH : H2O = 1 : 0.35 : 25.

XRD characterization results confirmed the formation of ZSM-11 zeolite.The SEM results show that the ZSM-11 zeolite crystal morphology is oval with crystal growth in all directions.Immersion of the synthesized ZSM-11 zeolite into AgNO3 solution and followed by calcination resulted in zeolite Ag-ZSM-11 which has different optical properties compared DOUBLE-FOIL SHAVER to the initial ZSM-11 zeolite.Zeolite ZSM-11 gives purple luminescence while zeolite Ag-ZSM-11 gives pink luminescence when illuminated under UV lights.
