Open Access Publication of the Month – Dr. Yulia Mourzina (IBI-3) et al.
1 August 2024
To encourage us all to broaden our horizons, each month the Central Library selects one open access publication from the JuSER publications portal to be featured in the newsletter of Forschungszentrum Jülich.
In the open access publication of the month, Yunong Zhang, Andreas Offenhäusser, and Yulia Mourzina (all IBI-3) write about the mechanism and properties of a self-powered H2O2 electrochemical sensor based on a fuel cell configuration.
The operating principle of a fuel cell is attracting increasing attention for the development of the self-powered electrochemical sensors (SPES). Unlike conventional electrochemical sensors, SPES convert the chemical energy of the analyte directly into electrical energy and generate signal without external power supply and modulation. Thus, the SPES offer energy-saving property, the simplicity in device, and better compatibility for applications in wearable equipment, in vivo and in situ measurements. The dual redox property of Hydrogen peroxide (H2O2) makes it possible to develop H2O2 SPES using the H2O2 analyte as both an oxidant and fuel by fabricating a membrane-less galvanic cell. However, the catalytic materials for different reaction pathways of H2O2 at the cathode and anode in a one-compartment cell are crucial for the characteristics of SPES.
The article presents functional studies, mechanisms, and properties of a novel H2O2 SPES with an enzyme mimic material, and highlights perspective of this concept in sensor development. Furthermore, since the H2O2 SPES is based on the principle and configuration of fuel cell, the results of power output tests suggest the possibility of applying these materials in the environmentally friendly energy storage and conversion systems.
The open access publication entitled "A Study on the Mechanism and Properties of a Self-Powered H2O2 Electrochemical Sensor Based on a Fuel Cell Configuration with FePc and Graphene Cathode Catalyst Materials" was published in the journal Biosensors.
