Since materials science is of great importance, the application of composite materials based on carbon nanotubes (CNTs) is widely investigated. Current work is aimed at preparing nanocomposites of TiO 2 /MWCNT using an impregnation method combined with slow hydrolysis. Different titanium alkoxide compounds as Ti(OEt) 4 , Ti(OiPr) 4 , and Ti(OBu) 4 , respectively, were used as precursor materials to cover the surface of CNTs in ethanolic medium. In our samples the mass ratio was 10:1 (TiO 2 :MWCNT). The produced composite materials were characterized by X‐ray diffraction (XRD), energy‐dispersive X‐ray spectroscopy (EDX), Raman microscopy, transmission (TEM) and scanning electron microscopy (SEM) techniques; moreover, thermal analysis and the determination of the specific surface area (BET) were also carried out. These as‐prepared TiO 2 /MWCNT composites were also tested as photocatalysts in degradation reaction of the model compound salicylic acid.
