Özet

This work examines the effect of gold nanoparticle (Au NP)- graphene oxide (GO) on the adsorption of dibenzothiophene (DBT) compounds. Au NP-GO were also used as an absorbent to produce nanoscale samples of DBT self-assembled monolayers (SAMs) on Au NP-GO. The influences of DBT adsorption on the size and the time of patterns were investigated. Atomic force microscopy (AFM) and Transmission electron microscopy (TEM) measurements showed that all of the uniformly distributed on Au NP- GO preliminary results indicated that the diameter and the density of DBT adsorptive can be controlled by controlling concentration of GO and Au NP and adsorption time during DBT the stage of SAMs. Photocatalytic oxidation of DBT was studied over Au NPs incorporated DBT Au NP-GO- DBT catalyst under UV radiation.
