The CuZr2S4 and CuZr2S4/rGO nanocomposites have been successfully done by the hydrothermal method. The optimized materials will be performed by several techniques like XRD, FT-IR, Raman, FE-SEM with elemental mapping, EDX, and TGA analysis. The CuZr2S4 nanomaterial was shown the Aloe Vera plant-like morphology will appear in the FESEM measurements. A CuZr2S4/rGO nanocomposite was enhanced for dye degradation in presence of MB dye with a visible light condition. This CuZr2S4/rGO nanocomposite didn't retard in future research and it's participating as well known properties and photocatalytic activity. Thermal analysis (TGA) was identified the three stages of decomposition with depends on the molecules' nature. Meanwhile, all kinds of characterization results as remarkably more suitable for this work, and CuZr2S4 and CuZr2S4/rGO nano composites were potentially high-quality performances. Finally, CuZr2S4 nanomaterial has been tested antibacterial analysis and it should be against Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans pathogens. However, we are identified to this material will not be performed in the antimicrobial effect.
