研究目的
Investigating the effect of Zn content on the physicochemical characteristics and photoactivity of ZnO supported activated carbon in phenol removal via photooxidation mechanism.
研究成果
The dispersion of ZnO on activated carbon affects the specific surface area and photocatalytic activity in phenol removal. The highest activity was achieved by ZnO/AC-5.0, indicating that the activity is influenced by a combination of parameters rather than individually.
研究不足
The study does not provide a quantitative relationship between the specific surface area, band gap energy, and Zn content parameters to the photocatalytic activity. Further photocatalytic modeling is required.
