Green synthesis and characterization of cadmium sulphide nanoparticles from Chlamydomonas reinhardtii and their application as photocatalysts
Source abstract
Abstract
Abstract This paper describes a facile, “green” method for the synthesis of cadmium sulphide (CdS) nanoparticles from Chlamydomonas reinhardtii. Morphological analysis by electron microscopy revealed the presence of spherical particles measuring approximately 5 nm. Structural analysis by powder X-ray diffraction and Fourier transform infrared spectroscopy confirmed the presence of cubic CdS nanoparticles that were capped with algal proteins. Optical analysis showed a significant blue shift in the optical band gap that could be ascribed to quantum confinement. The photocatalytic ability of these nanoparticles against methylene blue under UV light was studied & was found to degrade 90% of the dye within 90 min. Trapping experiments indicate that photogenerated holes, OH were the main reactive species responsible for dye degradation. This one-step strategy using algal cell free extract to produce CdS nanoparticles is an economical, environmentally friendly approach for the large-scale synthesis of CdS nanoparticles that can be used in photocatalysis.
