Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="pssb201300077-sec-0001" sec-type="section"> <p>Multiwalled carbon nanotube (MWCNT)/tungsten trioxide (WO₃) composites were prepared by two different impregnation methods. Tungsten (VI) chloride (WCl₆) was chosen as precursor compound to cover the surface of MWCNTs using either a simple or a combined impregnation technique. The applied mass ratio of MWCNT:WO₃ was 1:15 for each sample. Two different temperatures (450 and 700 °C) were applied during the calcination process depending on the type of the synthesis method. The produced composite materials and the reference WO₃ sample were characterized by transmission and scanning electron microscopies, Raman microscopy, and X‐ray diffraction. The results show that using varying both solvents and methods has a significant effect on the formation of composite materials. As prepared MWCNT‐based composites are planned to be applied in gas sensing techniques or in photocatalytic processes in the near future.</p> </sec> </abstract>
