Abstract
The highly reactive nature of reactive oxygen species (ROS) makes it widely used in environmental and health related fields. Conventionally, there are only two kinds of catalysts used for ROS generation, photocatalysts and piezocatalysts. However, their usage is limited due to various environmental and physical factors. Over the past few years, it has paved the way for the development of a novel catalyst which relies on temperature difference for ROS generation, called thermalcatalyst. Being the most important environmental factor in daily life, temperature exactly has a tremendous potential for applications. In this study, the experiment using thermoelectric materials as thermalcatalysts to generate ROS by controlling the temperature difference was performed. Furthermore, the produced ROS can kill the bacteria because of oxidative damage, which makes the thermalcatalyst ideal for disinfection. In order to increase the practicality in daily life, bismuth telluride (Bi2Te3), serving as the thermalcatalyst, was coated on the carbon fiber fabrics (Bi2Te3@CFFs) as an antibacterial filter. In conclusion, the results present that the thermoelectric material such as Bi2Te3 exhibited the significant antibacterial activity, providing a great potential for ROS-related applications.
