With the increasing environmental water pollution, there is an demand for efficient and sustainable wastewater treatment technologies. Photocatalysis, as environmentally friendly oxidation technology, shows significant promise degradation mineralization of organic pollutants in wastewater. Porous structured materials have received much attention from scientists photocatalytic due to their good dispersibility high specific surface area. Based on exploration recent research papers about various porous wastewater, we summarize synthesis methods loading catalysts, explore applications treating different types pollutants, finally present challenges prospects treatment. We hope that this review will inspire more researchers focus important field.

With the rapid progression of industrialization, water pollution has emerged as an increasingly critical issue, especially due to release organic dyes such methylene blue (MB), which poses serious threats both environment and human health. Developing efficient photocatalysts effectively degrade these pollutants is therefore paramount importance. In this work, titanium dioxide (TiO2) was modified with photosensitizer hemin hydroxyl-rich polymer polydopamine (PDA) enhance its photocatalytic degradation performance. Hemin PDA function photosensitizers, extending light absorption TiO2 into visible spectrum, reducing bandgap energy, promoting separation photogenerated electron–hole pairs through conjugated structures. Additionally, strong adhesion enabled transfer effective utilization electrons, while abundant phenolic hydroxyls increased MB adsorption on photocatalyst’s surface. Experimental results demonstrated a significant enhancement in activity, 1%PDA/3%hemin/TiO2 composite achieving rates 91.79% under UV 71.53% within 120 min, representing 2.22- 2.05-fold increases compared unmodified TiO2, respectively. This research presents modification approach provides important guidance for designing high-performance TiO2-based aimed at environmental remediation.
