Abstract: A comprehensive chemistry experiment was designed based on scientific research principles. Molybdenum disulfide (MoS₂) nanosheets were synthesized via a hydrothermal method. The effects of pH and temperature on the peroxidase-, catalase-, and superoxide dismutase-like activities of MoS₂ were evaluated. Additionally, the antibacterial activity of MoS₂ nanozyme was assessed. This experiment provides students with opportunities to broaden their scientific perspectives, stimulates their interest in research, and fosters a sense of scientific innovation.

Key words: Molybdenum disulfide, Nanozyme, Antibacterial activity, Comprehensive chemistry experiment
