This book is focused on the preparation of a MWCNTs/P25 composite, and analyzing the prepared composite using different techniques. The adsorption capability of the MWCNTs and the photocatalytic activity of the synthesized MWCNTs/P25 samples were quantified in terms of their adsorption capacity and the photocatalytic degradation of organic dye. This research consists of three main parts. In the first part, the MWCNTs/P25 composite was synthesized using simple evaporation and a drying process. In the second part, the structural, morphological and chemical properties of the synthesized...
