The student does not provide a focused and detailed description of the main topic, lacking cohesive discussion on the significance of photocatalysis and its applications. The research question also lacks clarity and could benefit from rephrasing for deeper analysis. Background information is insufficient, failing to comprehensively cover titanium dioxide (TiO2) and its photocatalytic properties, while key terms and concepts need better explanation for reader understanding. While the methodology is appropriate and focused on the research question, it lacks explicit details on managing controlled variables, safety hazards, ethical concerns, and environmental issues related to the experiment, which are essential for ensuring the relevance and validity of the results.
