“…Several physical deposition techniques for the preparation of TCOs exist, but chemical solution based techniques offers several advantages. TCO thin films of In2O3 ), SnO2 (Sladkevich et al 2011) and ZnO (Lima et al 2007) have all been prepared by the modified Pechini method, both by spin coating (Sunde et al 2012) and dip coating (Kundu and Biswas 2008).…”

The modified Pechini method has become one of the most popular synthesis methods for complex oxide materials due to its simplicity and versatility. The method can be applied to synthesize nano-crystalline powders, bulk materials as well as oxide thin films. Here, we present a comprehensive review of the method with focus on the chemistry through the three stages of the process; preparation of stable aqueous solution, poly-esterification to form a solid polymeric resin and finally decomposition/combustion of the resin to form an amorphous oxide followed by crystallization of the desired oxide phase. The review include

“…Among which, ZnO has wide applications in the areas such as solar cells [2][3][4], catalysis [5,6], sensors [7], laser diodes [8] and varistors [5,9]. Various techniques had been employed for the synthesis of the nano/micro structured ZnO such as sol-gel process [10], homogeneous precipitation [5], thermal decomposition [11], microwave heating [12], conventional hydrothermal [13][14][15], etc.…”

Effect of reducing agents on the structure of zinc oxide under microwave irradiation

2013

Zinc oxide was synthesized from zinc sulphate using different reducing agents under microwave irradiation. The influence of sodium borohydride, hydrazine hydrate and urea on the shape and size of the products were investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD). SEM showed the nano-sized spherical and rectangular shaped structures in case of sodium borohydride and hydrazine hydrate, whereas micro-sized hexagonal structures were formed in case of urea under the same irradiation power. The reducing agents played an important role in forming the various structures. Thus different shapes and size of structures were produced by only varying the reducing agent, which had wide applications in various fields.

Zinc oxide (ZnO) is one of the most important metal oxides having various applications in gas sensors. In the present work, ZnO nanoparticles were synthesized via sol-gel method. The nanopowder was then hydraulic-pressed and pre-sintered at 400°C to be molded into tablets with radius of 13 mm and thickness of 1.4 mm. Then, the sensor characteristics of ZnO nanopowder tablets were evaluated with respect to the ethanol. Finally, the tablets were doped with iron (Fe) and copper (Cu), and the effect of doping on sensing properties was studied.
