Thermal polymerization of pyrrole was performed using silver nitrate as source of silver ions followed by its conversion to Polypyrrole (PPy)/Ag nano-comoposites without using any external oxidizing agent or solvent. The formation of PPy was monitored by UV-Visible absorption spectroscopy showing a band at approximately 464 nm. XRD measurement confirmed(More)
Simultaneous in situ reduction of hexachloroplatinic acid by the amine group in the pyrrole monomer and oxidation of pyrrole to form polypyrrole (PPy) was examined. The reactions were performed at various temperatures to understand the degree of reduction of platinum precursor as well as doping of polypyrrole with Pt(II) chloro-complex.

TiO2 nanorods have been successfully obtained with hydrothermal method by treating TiCl3 with NaOH and NaCl aqueous solution at 180 o C for 24h in an autoclave. The present investigation deals with the preparation of TiO2 nanorods and gas sensing performance of TiO2 based thick film resistors. The Thick films of synthesised material were prepared by(More)
Nanostructured SnO2 thin films were prepared by spray pyrolysis technique onto glass substrates with different thickness by varying quantity of precursor solution. The structural, optical and electrical properties of these films have been studied. The crystallographic structure of the films was studied by X-ray diffraction (XRD). It is found that the films(More)
Herein we describe synthesis of ZnO nanoparticles by using alkaline solution of ZnX2 (X = NO3, Cl) under ultrasound energy of 20 KHz. The reaction can be completed in about 1-2 hours. As prepared powders were analyzed by XRD measurement to find that the product is hexagonal phase pure ZnO. UV-Visible measurement of aq. solution showed absorption band at(More)
In this work TiO2nanoparticals of hexagonal shape were prepared by using TiCl3, the TiO2 thick films were prepared by using screen printing technique. The films were characterized by scanning electron microscopy (SEM), UV visible technique, Transmission electron microscope (TEM) and Selected area diffractogram (SAED). The effect of change in nutrient such(More)
