Lousy odor is severe pollution in natural rubber processing industries and the air pollution treatment by using photocatalytic decomposition method has not much known. This study aims to explore the photocatalyst preparation and characterization of Fe doped ZnO immobilized on fiberglass cloth. Fe doped ZnO was prepared both with and without co-precipitation agent of NaOH. Both methods confirmed the metal existence and gave crystallite catalyst particles with mean diameters of 50 nm according to XRD characterization methods. SEM-EDS analysis showed Fe-ZnO particles prepared without co-precipitation were less aggregated particles than those made with the other method. EDS data identified the elemental composition of Zn, Fe, and O, and the fiberglass cloth composition, including Si and Mg. In the co-preparation method, sodium was always existed along with Fe and ZnO. DR-UV analysis showed the bandgap of Fe-ZnO was 3.20 and 3.22 eV without and with co-precipitation methods, respectively. TEM analysis of the catalyst slurry shows all particles were agglomerated in both preparations. Spherical-like particles existed non-precipitation method, and a spherical- and rod particle shapes were detected in co-precipitation preparation. The non-co-precipitation process was a preparable step in immobilization of the Fe-ZnO particles onto fiberglass cloth
