Abstract: This study introduces an innovative chemical experiment focusing on sulfur-vacancy-modified ZnIn₂S₄/TpPa-1 S-scheme heterojunction for boosted photocatalytic hydrogen production. In the experiment, Sv-ZnIn₂S₄/TpPa-1 composite is synthesized via microwave-hydrothermal method, followed by centrifugation for product separation and purification. Hydrogen yield is quantitatively analyzed using online gas chromatography to determine the hydrogen production rate, while X-ray photoelectron spectroscopy is applied to elucidate the photogenerated charge transfer mechanism in the S-scheme heterojunction. This comprehensive experiment integrates fundamental knowledge and practical skills from inorganic chemistry, physical chemistry, and analytical chemistry, along with training in advanced instrumentation. It also addresses the research hotspot of photocatalytic water splitting for hydrogen production. Through this experiment, students can reinforce their theoretical knowledge and experimental skills, while fostering scientific research enthusiasm. The design facilitates the development of scientific thinking methods and research capabilities, achieving the objectives of innovative experimental pedagogy. Furthermore, the teaching approach incorporates integrating scientific research into education, curriculum-based ideological and political elements, and value-oriented development, systematically cultivates interdisciplinary talents for national modernization. This approach also guides students in establishing core values including technological patriotism, green development, and collaborative innovation.
