| Abstract: | CdO and CdS nanocrystals have been prepared via
simple thermal treatment of coordination polymers, viz., [Cd(dca)2(Mim)2]n
and [Cd(SCN)2(Bim)2]n (where Bim and Mim are benzimidazole and 1-methylimidazole respectively) as precursors at 600–650 °C in air for 2 h. A variety of
techniques like infrared spectroscopy, X-ray diffraction, scanning
electron microscopy and thermal gravimetric analysis have been employed
to carry
out structural characterization of these nanoparticles. The optical band gap of
these materials, estimated to be about 2.43 and
2.50 eV respectively, establish a relationship between energy band gap of
bulk and nanomaterials. Photocatalytic reactivity of these nanomaterials are
evaluated by studying the degradation of
C. I.
Reactive Yellow 84, a popular
and widely used reactive dye in cotton industry. |
