Photocatalytic Nanomaterials for Environmental Remediation
Due to industrialization and urbanization, pollution of water, air, and soil has become a severe issue. To tackle this crisis, photocatalytic nanomaterials have emerged as a promising, green, and effective technology that uses light to neutralize or degrade pollutants.

Photocatalytic Nanomaterials Photocatalytic nanomaterials are nanoparticles that, in the presence of light (sunlight or artificial), catalyze chemical reactions. These materials purify the environment by breaking down pollutants—such as organic compounds, heavy metals, and microbes—into harmless substances. |
Working Mechanism
- Light Absorption: Materials (such as TiO₂, ZnO) absorb UV/visible light.
- Formation of Electron-Hole Pairs: Light energy excites electrons, ....
