Triboelectric nanogenerators (TENGs); Chemical modification; Cellulose and cellulose derivatives;  Tribo-filters.

Triboelectric nanogenerators (TENGs) are used to enhance air filtration efficiency through the triboelectric effect. By chemically modifying cellulose with electro-donating and electro-accepting functional groups, the triboelectric properties are improved. This leads to higher output performance and better filtration capabilities, including the removal of particulate matter and harmful gases. Cellulose-based TENGs are effective in filtering pollutants and can also be used for self-powered sensing applications, making them a sustainable and innovative solution for air purification.
