Solution-processed nickel oxide films and their liquefied petroleum gas sensing activity

Abstract

Present article demonstrates the facial synthesis of nickel oxide (NiO) films via an easy and costeffective successive ionic layer adsorption and reaction (SILAR) method onto glass substrate using nickel (II) chloride as precursor and their gas sensing activity towards different target gases. Structural elucidation and elemental composition analysis measurements were conducted using X-ray diffraction, Raman and energy dispersive X-ray techniques, respectively. Platelettype morphology was confirmed from the plane-view images recorded on field-emission scanning electron and transmission electron microscopes at different magnifications. Chemoresistive performance of NiO films was carried out towards hazardous and explosive gases such as ammonia, methanol, ethanol, liquefied petroleum gas (LPG) and nitrogen dioxide as a function of working temperature and gas concentration. Amongst diverse gases, NiO sensor film

The Synthesis Methods of Nickel Oxide Nanostructures - A Brief Review

“…The strongly adherent and uniform thin films were obtained at 333K temperature and time period of 30 seconds. NiO thin films with platelet-type morphology were synthesized on glass substrate using nickel (II) chloride and ammonia as precursors for gas sensor application [51]. K. S. Klepikova et al deposited NiO and Li-doped NiO thin films with activation energy Ea = 0.1 eV and Ea = 0.25-0.31 eV on glass substrate using the same precursors.…”
