Abstract

Powders of nanostructured were prepared using ultrasonic atomization technique. These powders were characterized using XRD, SEM, EDAX and TEM. The average grain size was observed to be near about 20 nm. Thick films of this powder were prepared using screen printing technique. Platinum is loaded on nanostructured ZnO films using dipping pure ZnO films into an aqueous solution of chloroplatnic acid for different intervals of time. The detection of the pure and Pt-loaded nanostructured ZnO thick films was tested on exposure of hazardous chemical i.e simulants of CWA such as, dimethyl methyl phosphonate, 2-chloroethyl ethyl sulfide and 2-chloroethyl phenyl sulfide. Both the pure and Pt-ZnO thick films showed higher response to DMMP.
