DEVELOPMENT OF CARBON NANOTUBE AS HIGHLY ACTIVE PHOTOCATATLYTIC ADSORBENT FOR TREATMENT OF ACID RED 88 DYE

Abstract

In recent years, photocatalysts have been used in various fields, and are particularly attracting attention in the fields of environment, medicine, and agriculture. A large number of catalytic active sites are required to produce a more efficient photocatalyst, and for that purpose, a large specific surface area is desired. Therefore, in this study, in order to develop a highly active photocatalytic material, the outer diameter of titanium oxide nanotubes was controlled by a template synthesis method using carbon nanotubes with different outer diameters to increase the specific surface area. Characterization was carried out by using diffent analytical instruments such as UV-Spectrophotomoter, XRD, SEM, TEM, BET. Results show using titanium oxide nanotubes with a smaller outer diameter tended to have higher photocatalytic activity (almost complete degradation was obtained when 10-20nm was used).
