Abstract:
Recently, the use of various dyes in the cellulose, textile, plastics and rubber industries has resulted in severe
toxic and dye contamination of wastewater. These toxic dyes are not biodegradable and have a detrimental effect
on the environment, blocking sunlight and reducing photosynthesis. Consequently, there is an urgent
need to develop a low-cost effective technology for purifying wastewater from harmful organic pollutants. In
this context, photocatalysis is an advanced, environmentally friendly oxidation process for wastewater treatment.
Recent studies have shown that the use of semiconductor photocatalytically active materials with a
wide band gap is an effective method for the decomposition of organic pollutants in aqueous solutions. In this
work, a low-cost technology for the synthesis of composite semiconductor zinc oxide / graphene oxide (ZnO /
GO) materials by chemical deposition from an aqueous solution has been developed. The morphology, structural
and photoluminescent properties of the synthesized ZnO/GO samples with different graphene oxide
concentration have been studied. The research of the photocatalytic activity of synthesized zinc oxide –
graphene oxide composite materials is carried out by observing an aqueous solution of rhodamine B dye degradation
under ultraviolet illumination.
