 This study aims to synthesize eco-friendly nanocatalysts such as reduced graphene oxide, argio, zinc oxide, zeno, and reduced graphene oxide, zinc oxide, argio and zeno for efficient photocatalytic degradation of methylene blue dye using direct sunlight irradiation. The synthesized nanocatalysts were characterized using various techniques and their photocatalytic degradation efficiency reached up to 66 percent, 96.5 percent, and 99 percent, respectively, with a low catalyst load of 20 milligrams.
