چکیده

This work aimed is to synthesis a well dispersed zinc oxide (zno) nanoparticles (nps) decorated on graphene oxide (go) nanosheet with a practical way by using sol-gel technique. zinc acetate dehydrate (zn(ch_3coo)_2·2h_2o) was used as precursor of zno and absolute ethanol as solvent. 1 weight percent (wt%), 5 wt%, 10 wt%, and 20 wt% of zno was decorated on go nanosheet. a series of analysis was carried out to characterize the synthesized zno-decorated go nanocomposite material. the results of xrd analysis show some long area of peak at 25° to 80° allocate for zno in the zno-decorated go nanocomposite material. by performing zeta potential analysis, the findings show that there was increment of negative surface charge on zno-decorated go nanocomposite material. the experiment result also found that the hydrodynamic particle size of zno-decorated go nanocomposite material become larger when high zno loaded. fesem micrographs demonstrated that spherical-shaped of zno nps appeared on the go nanosheet with further proved by edx where the content of zno-decorated go nanocomposite material was composed by 71.3 wt% of c, 17 wt% of o, and additional element of 11.7 wt% of zn. thus, it can summarize that the synthesized zno-decorated go nanocomposite material was high in purity. the findings in this study proved that zno nps loading in zno-decorated go nanocomposite material were successfully synthesized by sol-gel method. a zno-decorated go nanocomposite material with layering zno nps on go nanosheet was produced.
