CNT/TiO2 Hybrid Nanostructured Materials: Synthesis, Properties and Applications

The study of semiconductor photocatalysts is essential to achieve sustainable solutions for application in energy generation and treatment of environmental pollution. Titanium dioxide (TiO2) is one of the most researched photocatalysts because of its abundance and non-toxicity, but its low efficiency, when deployed as a photocatalyst, can sometimes hinder its potential for these applications. Combining nanostructured TiO2 with carbon nanotubes (CNTs) to form hybrid materials can help overcome some of the metal oxide limitations, such as a large band-gap and a high electron–hole recombination rate. This chapter summarizes some of the CNT/TiO2 nanostructured materials that have been reported in the last years and outlines their morphologies, methods of synthesis, and applications.
