Synthesis of Tin oxide nanoparticles using Nelumbo nucifera leaves extract for electrochemical sensing of dopamine

Abstract

In this investigation, SnO2 nanoparticles are prepared through environmental benign method using Nelumbo nucifera (lotus leaf) leaves extract as a reducing agent without any other reagents. The phase formation and the morphology of the as-synthesized SnO2 nanoparticles are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The nanoparticle size is obtained using selected area diffraction patterns of transmission electron microscope (TEM). The synthesized material modified glassy carbon electrode (GCE) is used for electrochemical detection of the dopamine (DA). In cyclic voltammetry (CV), the modified GCE shows effective electrochemical sensing performance than the bare GCE electrode. The limit of detection (LOD) and limit of quantification (LOQ) of DA were calculated by differential pulse voltammetry (DPV). Aforementioned material has high sensitivity and selectivity towards DA oxidation through electrochemical sensing.

Electrochemical Detection of Dopamine in the Presence of Uric Acid at Cerium Oxide and L-Tyrosine Mixture Modified Carbon Paste Electrode: A Cyclic Voltammetry Study

“…SEM analysis.-The morphological and the purity of the as synthesized CeO 2 NPs are observed through SEM and EDX analysis. 1,16,17 As synthesized CeO 2 NPs displays that, it is porous in nature with accumulation of the particles. The SEM analysis says that they are porous nature is why because during the combustion process there is an evolution of gases and water vapors.…”

Crystallinity Study of Electrodeposited SnO₂ on FTO Substrate

“…All the above-mentioned properties of tin oxide make it an appreciable material for a variety of applications-Li-ion batteries [11], and catalysts [12]. Several methods have been implemented in the fabrication of tin oxide nanoparticles by researchers, some of which are hydrothermal [13], green synthesis [14], controlled precipitation [15], leaching [16], sol-gel combustion [17], and so on. Several research studies have explored various methods for synthesizing tin oxide nanoparticles.…”
