Hypothesis
The introduction of Ni(OH)2 as a cocatalyst will enhance the photocatalytic performance of CdS for hydrogen production.
Conclusion
The CdS/5%Ni(OH)2 composite demonstrated a hydrogen production rate that is 6.9 times higher than that of blank CdS, indicating its superior photocatalytic performance.
Supporting Evidence
- The optimal CdS/5%Ni(OH)2 composite achieved a hydrogen production rate of 10,525.72 μmol/g/h.
- Adding Ni(OH)2 significantly improved the stability of the CdS photocatalyst.
- The introduction of Ni(OH)2 enhanced the separation of photogenerated charge carriers.
- CdS/Ni(OH)2 composites showed better photocatalytic performance compared to blank CdS.
- Characterization techniques confirmed the successful synthesis of the CdS/5%Ni(OH)2 composite.
Takeaway
This study shows that adding a small amount of nickel hydroxide to cadmium sulfide can make it much better at producing hydrogen from sunlight.
Methodology
The CdS/Ni(OH)2 composites were synthesized using a hydrothermal method, and their photocatalytic performance was evaluated through hydrogen production tests.
Limitations
The study does not explore the long-term stability of the photocatalysts beyond five cycles.
