Photocatalysis has gained huge research interest for the degradation of textile dyes from the water environment. In addition, researchers are eager to develop catalysts for the fast degradation of organic dyes in ambient conditions without any stimulants. In this regard, a phytogenic metal oxide-based MoO₃/ZnMoO₄ catalyst is synthesized in the current study using Abies pindrow Royle (A.pindrow) foliar extract for the degradation of methyl orange from water bodies. A.pindrow mediated MoO₃/ZnMoO₄ composite is prepared via sol-gel synthesis route following thermal decomposition in air. The phase analysis and chemical composition of the prepared composite are confirmed by powdered X-ray diffraction, energy dispersive spectroscopy, Raman spectroscopy while the surface morphology is examined by field emission scanning electron microscopy. The synthesized MoO₃/ZnMoO₄ catalyst is employed to degrade MO in the aqueous environment in the presence of solar light and in dark ambient conditions without any stimulation. It is revealed that A.pindrow framework-derived MoO₃/ZnMoO₄ catalyst exhibits excellent catalytic potential to degrade MO in aqueous solutions with 90% and 99 % degradation efficiency under dark and light conditions, respectively, within 10 minutes. Moreover, the catalyst demonstrates substantial stability until four cycles of experiments with pseudo-first-order kinetics under light and dark conditions (R² <1). Thus, the overall findings of the present study highly suggest the significant potential of MoO₃/ZnMoO₄ catalyst for the degradation of MO even in dark ambient conditions.
