Quantifying instant water cleaning efficiency using zinc oxide decorated complex 3D printed porous architectures

Area of Science:

• Materials Science
• Environmental Science
• Nanotechnology

Background:

• Industrialization degrades water quality, necessitating effective purification and monitoring for human and aquatic health.
• Porous materials with high surface areas enhance cleaning efficiency.
• 3D printing enables precise control over material porosity and surface area.

Purpose of the Study:

• To develop and evaluate 3D printed architectures decorated with zinc oxide (ZnO) nanosheets for water purification.
• To compare the catalytic performance of different 3D printed structures (Schwarzites and Weissmuller).
• To establish a user-friendly method for real-time monitoring of dye removal efficiency.

Main Methods:

• Growing catalytically active ZnO nanosheets on 3D printed Schwarzites and Weissmuller architectures.
• Evaluating the porosity and surface area of the decorated structures.
• Testing the synergistic adsorption and photodegradation performance for mixed dye removal.
• Utilizing smartphone-based colorimetric measurements for quantitative analysis.

Main Results:

• The Weissmuller structure, with ~69% porosity and high surface area, demonstrated superior catalytic performance compared to Schwarzites.
• A synergistic adsorption and photodegradation effect led to ~95% removal of mixed dye within 10 minutes.
• The decorated 3D printed structures showed high stability and no ZnO residuals after recycling.

Conclusions:

• Decorated 3D printed Weissmuller structures offer an efficient and stable solution for water purification.
• Smartphone-based colorimetric detection provides a versatile, user-friendly tool for real-time analysis of water pollutant removal.
• This approach bypasses the need for sophisticated instrumentation, making water quality monitoring more accessible.
