Future Air Purification by Using TiO2

Our project aims to develop an ‘Air Pollution Absorbing Material’ by integrating titanium dioxide with conventional components. Titanium dioxide, commonly found in toothpastes and cosmetic products, acts as a self-cleaning agent. This property allows the material to break down algae and dirt, ensuring a cleaner surface over time. The core of the material is a mixture of traditional cement and titanium dioxide, forming a unique composition that permits airflow while trapping nitrogen oxide particles— a key contributor to smog. When exposed to UV light, titanium dioxide acts as a catalyst, triggering a chemical reaction that neutralizes pollutants. The resulting smog residue is easily removed by light rain, maintaining the material’s effectiveness and appearance. This innovative and environmentally friendly solution leverages titanium dioxide’s properties to combat air pollution safely and contribute to public health.
