Abstract
Synthesis of zirconium oxide nanoparticles by the recently developed green approach is extremely promising because of its non-toxicity and environment friendly behaviour. Plant extract-facilitated synthesis is a promising approach that offers several advantages, such as reducing toxic byproducts and enabling control over nanoparticle size by using embedded phytochemicals. The phytochemicals present in plant extracts, such as aldehydes, ketones, amides, terpenoids, carboxylic acids, and flavonoids, play a significant role in nanoparticle synthesis. This study aims to synthesize ZrO2 nanoparticles using Bougainvillea glabra Choisy extract through green chemistry approaches and investigate their potential applications in the corrosion field. To optimize the synthesis process parameters, such as reaction time, temperature, and concentration of reactants, to achieve stable and uniformly distributed ZrO2 nanoparticles. The synthesized ZrO2 nanoparticles have been evaluated for anti-corrosive properties of copper metal immersed in hydrochloric acid. The weight loss technique shows good inhibition efficiency. Electrochemical impedance measurements indicate that an increase the charge transfer resistance (Rt), increase the double layer capacitance (Cdl) and corrosion current (Icorr ) values owing to the decreased thickness of adsorbed layer. FTIR spectra reveal that the protective film consists of Zr2+ - plant constituent complex.
