Zinc oxide nanoparticles (ZnO-NPs) are known as a material in the treatment of environmental pollutions. In this study, ZnO-NPs were synthesized using Boswellia mukul gum. The characterization of synthesized ZnO-NPs was performed UV–Vis spectroscopy, powder X-ray diffraction, FTIR, and field emission scanning electron microscopy. The obtained outcomes have illustrated that the synthesized nanoparticles had been in hexagonal shapes and contained a sheet form in the size of 20–50 nm. The antifungal assay of synthesized ZnO-NPs has been studied against Aspergillus niger and Aspergillus flavus, while the minimum inhibitory concentrations of both strains have been calculated to be 18 μg/mL. We have evaluated the photocatalytic activity of synthesized ZnO-NPs through the utilization of methylene blue (MB) (Q1/R4) under UV light. The photocatalytic results of MB dye show up to 70% degradation in 180 min, which indicates that the synthesized nanoparticles are capable of deteriorating artificial colors and can eradicate some environmental contaminants.
