Abstract
In this work, nano-inspired nickel oxide nanoparticles (NiO) and polythiophene (Pth) modified bioanode was prepared for biofuel cell applications. The chemically prepared nickel oxide nanoparticles and its composite with polythiophene were characterized for elemental composition and microscopic characterization while using scanning electron microscopy. The electrochemical characterizations of polythiophene@NiO composite, biocompatible mediator ferritin (Frt) and glucose oxidase (GOx) catalyst modified glassy carbon (GC) electrode were carried out using cyclic voltammetry (CV), linear sweep voltammetry (LSV), and charge-discharge studies. The current density of Pth@NiO/Frt/GOx bioanode was found to be 5.4 mA/cm2. The bioanode exhibited a good bio-electrocatalytic activity towards the oxidation of the glucose. The experimental studies of the bioanode are justifying its employment in biofuel cells. This will cater a platform for the generation of sustainable energy for low temperature devices.
Highlights
The advancement of technologies in the era of energy crisis are currently emphasising on the production of clean and green energy using efficient, sustainable and renewable resources [1]
This curiosity in research field leads to the development of enzymatic biofuel cells (EBFCs) [2]
Glucose-based EBFC seems to be a promising candidate for implantable applications, due to the availability of glucose and oxygen in physiological fluids that make the possibility for the generation of electrical power inside the living system
Summary
The advancement of technologies in the era of energy crisis are currently emphasising on the production of clean and green energy using efficient, sustainable and renewable resources [1]. This curiosity in research field leads to the development of enzymatic biofuel cells (EBFCs) [2]. Glucose-based EBFC seems to be a promising candidate for implantable applications, due to the availability of glucose and oxygen in physiological fluids that make the possibility for the generation of electrical power inside the living system. The glucose used as a fuel oxidizes at the anode via redox enzyme, whereas the reduction of oxygen takes place at the cathode, to carry out redox reaction [12]
