Preparation of nanoporous material containing sulfide-carboxyl group derived from rice plant

Abstract

In this research, a nanoporous material via the rice plant was prepared. Rice plant contains a large amount of silica. From the process of burning rice husks, it is possible to prepare the rice husk ash (RHA). And through the sol-gel process, RHA can be reacted with 3-(mercaptopropyl)triethoxysilane (MPTES) to prepare the polymer RHACSH. RHACSH can be entered in chemical reactions for the production of Nanoporous Material labelled as RHACS-ACOH. Several physical techniques were used to study the RHACS-ACOH. CHNS analysis and FT-IR spectra confirmed that the chloroacetic acid (Cl-ACOH) acid have incorporated on RHACSH. Amorphous nature of RHACS-ACOH has been recognized by X-ray diffraction. The nanostructure of the RHACS-ACOH has been recognized by many techniques such as transmission electron microscopy (TEM) and surface area measurements. The surface area measurements indicated that RHACS-ACOH had a specific surface area of 66.13 m2g-1 and a narrow average pore diameter of 6.97 nm. The decomposition stages of the RHACS-ACOH were studied using thermogravimetric analysis (TGA-DTA) between 30-900 °C.
