Abstract

The idea of this research depended on the preparation of nanoporous material via rice husk based on the silica material. The silica material is prepared from the rice husks in appropriate chemical method. Where it is known that the rice husks are produced by the production of rice plants that are too large quantities and cause high pollution in environment. Instead, the husks is embedded or burn in the exposed atmosphere in urban and rural areas could benefit from it by the suitable chemical treatment and burning it in controlled conditions, it produces pure silica labeled as RHA (Rice Husk Ash) can be entered in chemical reactions for the production of Nanoporous Material labeled as RHAC-Pd(DTO)2 .This Nanoporous Material is inorganic-organic hybrid. According to analysis of CHNS and FT-IR spectra can be conclude that the bis- dithiooxamidepalladium(II) chloride [Pd(DTO)2]Cl2 has successful incorporation on RHACCl . X-ray diffraction technique was used to determine the amorphous formula of [Pd(DTO)2]Cl2, while the Transmission electron microscopy (TEM) technique was used to confirm its nanostructure of compounds. The surface area measurements indicated that [Pd(DTO)2]Cl2 had a specific surface area of 70.83 m2g1- and a narrow average pore diameter of 3.25 nm. Thermogravimetric analysis (TGA-DTA) of RHAC-Pd(DTO)2 indication that the physical adsorb water was lost between 30-160 °C which means it is weakly bonded in the silica matrix, while the residual parts of material decomposed up to 300 °C.
