Hypothesis
Can ZnO-doped CuO nanocomposites improve photocatalytic and sensor performance?
Conclusion
The CuO+5%ZnO nanocomposite effectively degraded 71.35% of Congo Red and 53.35% of Methylene Blue dyes under UV light.
Supporting Evidence
- ZnO-doped CuO nanocomposites were synthesized at 500 °C and calcined at 1000 °C.
- The degradation efficiency of CuO+3%ZnO NPs reached 70% after 120 minutes under UV light.
- The optical energy band gap of the NPs was found to be between 2.1 and 2.5 eV.
- Cyclic voltammetry showed effective sensing of glucose and ascorbic acid.
- Photocatalytic activity was confirmed through the degradation of dyes in aqueous solutions.
Takeaway
This study shows that a special mix of materials can help clean up dirty water and detect important chemicals.
Methodology
ZnO-doped CuO nanocomposites were synthesized using the solution combustion method and tested for photocatalytic and electrochemical properties.
Limitations
The study does not address the long-term stability of the photocatalysts or their performance in real wastewater conditions.
