摘要：

Herein, we present pure nickel oxide nanoparticles (NiO NPs) and Sr doped NiO NPs SrxNi1-xO (x = 0.0, 0.01, 0.02, 0.03, 0.04) which are synthesized via hydrothermal approach. As-synthesized samples are analyzed through structural characterization techniques like x-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The single cubic phase is obtained for NiO NPs and the samples with low Sr dopant contents (1% to 2%); however, samples with high Sr dopant contents (3% to 4%) have a secondary phase (SrO phase). The particle size of Sr doped NiO NPs ranges from 50-100 nm, and the particles lose their uniformity as dopant concentration is increases. Electrical and dielectric characteristics of as-synthesized samples are studied, and the effect of Sr dopant contents is discussed. Electrochemical studies reveal that the selected samples exhibit remarkable catalytic activity toward glucose sensing owing to their specific structural and morphological characteristics.
