ABSTRACT
In last few decades, the growing industrial activities have resulted in an increasing amount of pollutants in the environment, which has become a burning problem all over the globe and it still is a challenge for many countries. Carbon nanotubes (CNTs) have attracted considerable attention because of their special structure and high mechanical strength, which makes them potential candidates for advanced composites. They can be semiconducting, semimetallic, or metallic in nature. CNTs are also efficient adsorbents due to their large specific surface area and hollow and layered structures. The chemical, physical, and mechanical properties of CNTs find applications in diverse fields. There are different types of nanotubes including single-walled nanotubes, double-walled nanotubes, and the multi-walled nanotubes. Apart from their different applications, these can be used as a photocatalytic material in pure form or in the form of a composite with some photocatalyst. Thus, CNTs can be used as a promising material in environmental cleaning. Here, use of CNTs as a photocatalytic material has been discussed.
