This would allow the use of an abundant and green energy source, sunlight, to derive chemical reactions. The objective of the presented project was to study the effect of alloying transition metal oxides TMOs (FeO) with ZnO on the photocatalytic process and find out whether alloying TMOs could introduce active photocatalysts active under visible irradiation or not. In particular, the current study involved preparation of (Fe₁-{u0353} Zn{u0353}O at x = 0.75) nanoalloys alone, enhanced by assembling over rGO nanosheets and doped with (Au-Ag) nanoalloys. The activity of the obtained nanomaterials was evaluated through the degradation of Chlorpyrifos (CP) as a model of pesticides. Moreover, the obtained nanomaterials were used as safe antifungal agents in inhibiting the linear growth of Aspergillus niger
