AI Technical Summary

Technical Problem

Existing photocatalytic cement-based composite materials suffer from low photocatalytic efficiency, high cost, poor durability, and limited functionality, making it difficult to achieve large-scale application and resource recycling, and thus failing to meet engineering requirements.

Method used

Fine aggregates loaded with photocatalysts are prepared by etching polymethyl methacrylate (PMMA) and combined with aluminum powder hydration gas generation to lift the photocatalytic fine aggregates to the surface of the material. Combined with a porous cement matrix, the light absorption efficiency and mass transfer efficiency of the photocatalyst are improved. The preparation process is simple and easy to scale up.

Benefits of technology

It significantly improves the light-receiving efficiency and mass transfer efficiency of photocatalysts, achieving efficient pollutant purification and resource recovery. The material has strong stability and engineering application potential, and is suitable for water purification and resource recovery in multiple scenarios.
