Fabrication of oxides of copper-nickel bimetallic nano particle using Zingiber officnale extract: an eco-friendly approach for electrochemical application of glucose detection
摘要
The oxidation of glucose’s C1 position is more facile than the oxidation of its main or secondary alcohol functionalities when supported metal catalysts like Au, Pd, and Pt are present. Hence an efficient and economic green methodology of conversion of glucose to gluconic acid using copper-nickel bimetallic catalyst is carried out. Zingiber officinale extract is prepared which is used for the green synthesis of bimetallic copper-nickel catalyst. The bimetallic catalyst is used for the conversion of glucose to gluconic acid. The bimetallic nano particles are characterized using UV–Visible spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR). The peak in UV–Visible spectroscopy at 380 nm resulted as the plant molecules acted as reducing and capping agent for the conversion of copper and nickel oxides to nano composites. FTIR peaks are observed at 583 cm−1 and 2362 cm−1 which corresponds to CuO and NiO composites along with hydroxyl groups. The conversion of glucose to gluconic acid is confirmed by Cyclic Voltammetry which shows electrochemical activity between − 0.8 and + 0.8 V with current increase. The process can be utilized to develop biosensors for glucose detection.
