Effect of ND-YAG Laser Time Variations for Zinc Oxide Photocratic Fabrication in Methylene Blue Degradation

In recent years, the world has witnessed a significant increase in water pollution due to industrial waste, agricultural runoff, and other human activities. This has led to a pressing need for effective and efficient water treatment methods. One of the promising approaches in this regard is the use of photocatalysts, which can break down pollutants and contaminants in water using light energy. In this study, we explore the effect of ND-YAG laser time variations on zinc oxide photocatalyst fabrication for methylene blue degradation.

Background and Significance

Methylene blue is a synthetic dye commonly used in textile and paper industries. However, its discharge into water bodies has been linked to various environmental problems, including water pollution and harm to aquatic life. The degradation of methylene blue is, therefore, a critical aspect of water treatment. Zinc oxide (ZnO) is a well-known photocatalyst that has been widely used in water treatment applications due to its high reactivity and stability. However, the efficiency of ZnO as a photocatalyst can be improved by optimizing its surface area and reactivity.

Methodology

In this study, we used the pulsed laser deposition (PLD) method to fabricate ZnO photocatalysts on the surface of glass substrates. The PLD method involves the use of a high-powered laser to deposit ZnO particles onto the substrate. The laser energy used in this study was 50 mJ, and the exposure time was varied to 5 minutes, 15 minutes, and 30 minutes. The wavelength of the laser was 1064 nm, and the energy was measured using energy meters from Coherent to ensure accuracy.

Analysis of Research Results

The test results show that different variations of laser exposure time have a significant impact on the effectiveness of methylene blue degradation. The decrease in the concentration of methylene blue was measured every two hours during exposure in the sun for four hours. Exposure to sunlight plays an important role in the process of photocatalysis, where ZnO functions as a catalyst that is activated by light, resulting in an effective chemical reaction in breaking the structure of the methylene blue molecule.

Effects of Variation Time Exposure

The analysis shows that the longer the laser exposure time, the higher the efficiency of methylene blue degradation. Variations in exposure to 30 minutes show the best results with the highest percentage of degradation compared to shorter exposure time. This is caused by an increase in energy absorbed by ZnO, which accelerates the process of breaking the molecules. Conversely, shorter exposure time, such as 5 minutes, produces lower degradation due to the limited energy absorbed to start the reaction.

Implications for Water Treatment

This discovery is very relevant in the context of water treatment, especially for areas that experience water pollution due to industrial waste. By utilizing ND-YAG laser technology in photocatalyst fabrication, the water purification process can be done more effectively and efficiently. ZnO as photocatalyst has been proven to be able to improve the process of degradation of pollutants, and PLD techniques offer innovative ways to increase surface area and photocatalyst material reactivity.

Conclusion

This study provides a deep insight into the effect of variations in the ND-YAG laser exposure time on ZnO photocatalyst fabrication in methylene blue degradation. The results show that the use of laser energy and optimal exposure time can increase efficiency in the water purification process. Further development in this technique has great potential to be applied in environmental solutions, especially in polluted water treatment.

Future Directions

The findings of this study suggest that the use of ND-YAG laser technology in photocatalyst fabrication can be a promising approach for water treatment. However, further research is needed to optimize the process and to explore its potential applications in real-world scenarios. Some potential areas of future research include:

  • Investigating the effect of different laser energies and exposure times on ZnO photocatalyst fabrication
  • Exploring the use of other photocatalysts, such as titanium dioxide (TiO2) and silicon dioxide (SiO2)
  • Developing new techniques for increasing the surface area and reactivity of photocatalysts
  • Investigating the potential applications of photocatalysts in other environmental solutions, such as air and soil pollution.

Recommendations

Based on the findings of this study, we recommend the following:

  • Further research should be conducted to optimize the use of ND-YAG laser technology in photocatalyst fabrication

  • New techniques should be developed to increase the surface area and reactivity of photocatalysts
  • The potential applications of photocatalysts in real-world scenarios should be explored.

Limitations

This study has several limitations, including:

  • The use of a single type of photocatalyst (ZnO) and a single type of pollutant (methylene blue)
  • The limited number of exposure times used in the study
  • The lack of control over other variables that may affect the photocatalytic process, such as temperature and humidity.

Future Research Directions

The findings of this study suggest that the use of ND-YAG laser technology in photocatalyst fabrication can be a promising approach for water treatment. However, further research is needed to optimize the process and to explore its potential applications in real-world scenarios. Some potential areas of future research include:

  • Investigating the effect of different laser energies and exposure times on ZnO photocatalyst fabrication
