Recently, there has been growing interest in the development of efficient photocatalysts forvarious applications, such as environmental remediation and optoelectronics. the synthesis ofnanocomposites has received attention due to their unique properties and potential applications invarious fields. Bismuth vanadate (BiVO۴) and bismuth sulfide (Bi۲S۳) are two promising materialswith strong visible light absorption capabilities. in this article, bismuth / bismuth sulfide / bismuthvanadate nanocomposite is prepared by hydrothermal method using ammonium metavanadate,bismuth nitrate, and thioacetamide reagents and was synthesized in the presence of hydrazine. Thepurity, structure and morphology of the produced nanocomposite were identified by XRD and FTIRanalyze. This nanocomposite can have high photocatalytic capability and can be used fordesulfurization of petroleum derivatives, and finally, by examining the photocatalytic performanceof this nanocomposite in desulfurization of petroleum derivatives, its effectiveness was confirmed.
