Abstract
Nanosized CdS/polymer composite fiber mats were fabricated via a facile electrospinning processing, and the as-prepared composite fiber mats showed excellent photodegradation ability to methylene blue (MB). Polymers bearing N and S atoms with affinity to Cd2+ ions were first synthesized and then used to prepare CdS/polymer composite fibers. In this work, coaxial electrospinning was employed to achieve the preparation of the desired composite fibers using special polymers as core and cadmium acetate [Cd(CH3COO)2] as shell. Then, fiber mats were immersed in thioacetamide (TAA) solution for several minutes, and CdS/polymer composite mats were obtained eventually. The photodegradation catalytic ability was tested using MB as a model dye under sunlight. The photocatalytic efficiency of the CdS/polymer composite fiber mat was recorded and studied by UV-visible spectra, and it showed high efficiency. Nanofiber mats will find real applications in the treatment of wastewater.
