Abstract

This research purpose is to use oil palm leaves as a source of silica in the synthesis of SnO2-SiO2 composites. Oil palm leaves were prepared by leaching method with 10% HCl to increase the silica content. SnO2-SiO2 was synthesised using the solid-state method with the help of a small amount of solvent. FTIR analysis showed Si-O-Si and O-Si-O peaks at wave numbers 1067.32 cm-1 and 796.38 cm-1 and Sn-O-Sn peak at wave number 541.87 cm-1. XRD analysis showed amorphous phase in SiO2 and crystalline phase in SnO2. The composite materials obtained have the potential to be utilised as adsorbents and catalysts in the wastewater purification process.
