Abstract

Sonochemistry is the implementation of ultrasound wave to chemical reactions and processes. Remarkable progress has been achieved over the years on ultrasonic-assisted hydrothermal synthesis in zeolites. Ultrasonic irradiation is gaining popularity among researchers due to its ability in enhancing the zeolite crystallization and shortening significantly zeolite synthesis duration. In this project, zeolite RHO were synthesized via ultrasonic irradiation and followed by hydrothermal synthesis. The effect of ultrasonic irradiation on the synthesis of zeolite RHO was investigated. The zeolite RHO samples were characterized with X-ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) coupled with Energy Dispersive X-ray (EDX). The application of ultrasonic irradiation treatment in current study has significantly shortened the synthesis duration of zeolite RHO from 7 days to 2 days compared to the conventional hydrothermal synthesis without ultrasonic irradiation treatment.
