BİYOKÜTLEDEN ÜRETİLEN KARBON ALTLIK ÜZERİNDE ZNO NANO-PARÇACIKLARIN BİRİKTİRİLMESİ VE KARAKTERİZASYONU

Abstract

In this study, zinc oxide (ZnO) nano-particles that is used in many application areas with high thermal and chemical stability, biocompatible, cheap and non-toxic properties; was deposited onto the porous carbon on bio-char produced from biomass. Rice husk was chosen as the biomass source. The results of the characterization studies applied before and after the carbonization process were presented in the study. Rice husk is a suitable raw material for the production of porous carbon material by carbonization method with its low moisture content (2.01 wt.%) and high volatile matter content (63.48 wt.%). It was observed that the surface area of the synthesized carbonaceous material was 79.63 m2/g and the average pore size was 5.07 nm. ZnO nano-particles were deposited on the carbon substrate using chemical bath storage technique. ZnO nano-particles characterized by scanning electron microscopy (SEM) and X-ray diffractometry (XRD). It was determined that they have crystalline structure and the surface morphology of all thin films are homogeneous and compact.
