Figure 1: Schematic presentation of the functionalization of MWCNTs and the coupling of CdSe nanoparticles with MWCNTs.

Mentions: The functionalized MWCNTs with Cd(NH3)42+ and Na2SeSO3 solutions which were prepared above were mixed together and the mixture was stirred and refluxed for at least 5 h. After the temperature of the mixture was brought down to room temperature, the mixture was filtered through Whatman filter paper. The solid obtained was collected and washed with distilled water for five times. After being dried in vacuum at 353 K for 8 h, the CNT-CdSe composite with chemical band was obtained. Figure 1 shows the schematic presentation of the functionalization of MWCNTs and the coupling of CdSe nanoparticles with MWCNTs.
