Abstract

It has been shown by the modification of multiwalled carbon nanotubes with cadmium sulfide quantum dots that nanocomposites based on multiwalled carbon nanotubes with monitored size of deposited cadmium sulfide nanoparticles can be fabricated. It has been shown that carbon nanotubes modified with CdS quantum dots are good catalysts for the oxygen electrodes of low-temperature fuel cells. The size of CdS nanoparticles was monitored by absorption spectra of a colloidal solution. The proposed method can be employed to fabricate nanocomposites from carbon nanotubes and semiconductor catalysts.
