Description
Summary:[Display omitted] •Fabricate the bismuth molybdate modified GO sheets (Bi2MoO6@GO) as photocatalyst via simple hydrothermal method.•Bi2MoO6@GO nanocomposite was characterized and optimized to check its performance as photocatalyst.•As fabricated composite exhibited the enhanced photocatalytic activity to remove the organic dyes from water. Utilization of solar energy for the degradation of organic pollutants is a promising sustainable approach. Here in this research work, bismuth molybdate (Bi2MoO6) nanoparticles (NPs) modified graphene oxide sheets (Bi2MoO6@GO) were employed as efficient photocatalysts for the removal of organic dyes under illuminated sunlight. The synthesized nanocomposite was subjected to characterization via XRD, FTIR, Raman, SEM, EDX and UV–Vis spectroscopic analysis. The photocatalytic efficiency of fabricated nanocomposite (Bi2MoO6@GO) has been studied against organic pollutants including rhodamine B and methylene blue in aqueous solution under direct sunlight irradiation. Bi2MoO6 decorated graphene oxide nano-photocatalyst exhibited 91 % and 88 % degradation of methylene blue and rhodamine B within ∼ 70 min with apparent rate constant values of 0.0323 and 0.0246 min−1, respectively. The study showed that fabricated photocatalyst (Bi2MoO6@GO) possesses a comparatively low band gap, heterogeneous morphology and boosted active surface area which makes it an efficient photocatalyst for the effective remediation of organic pollutants.
