Description	Journal: Journal of Physics D: Applied Physics In this present work, we explore the preparation of h-molybdenum oxide/reduced graphene oxide $(h-MoO_{3}$/rGO) nanocomposites via a simple precipitation technique to enhance the photocatalytic activity of $h-MoO_{3}$ under direct sunlight illumination. The phase formation $h-MoO_{3}$ was confirmed by x-ray diffraction studies, Fourier transform infrared spectroscopy and Raman spectroscopic studies revealed the formation of $rGO/h-MoO_{3}$ nanocomposites. The surface morphologies of the synthesized samples were analyzed through field-emission scanning electron microscopy. Moreover, the hazardous methylene blue dye degradation was studied to evaluate the photocatalytic activity of the prepared materials under direct sunlight illumination. The comparative results show that the $rGO/h-MoO_{3}$ composites exhibited higher catalytic activity than the bare $h-MoO_{3}$. The reason behind the enhancement of the photocatalytic activity was discussed in great detail. Moreover, in situ scavenger studies were carried out to probe the mechanism of photocatalysis.
