Abstract: Based on scientific research, a comprehensive chemistry experiment was designed as “Carbon nanotube/SnS₂ photoanode catalyst materials were prepared using the solvothermal method”. Characterizations of the materials were conducted using SEM (Scanning electron microscope), XRD (X-ray diffraction), UV-Vis (Ultraviolet-visible absorption spectroscopy), etc. Transient photocurrent response, electrochemical impedance and linear voltammetry scanning were used to analyze the water decomposition properties of the materials. This experiment enables students to master the preparation, characterization, and application of materials, fostering their scientific research literacy. Through hands-on experimentation, students can validate their learned knowledge, enhancing their problem-solving abilities. By understanding the properties and applications of the materials, the experiment also nurtures students’ awareness of energy crises and environmental protection.

Key words: CNTs/SnS₂, Material preparation and characterization, Comprehensive experiment
