Review—Biomass Derived Carbon Materials for Electrochemical Sensors

Abstract

Sensors have become integral part of our lives. Electrochemical sensors are the oldest and the most commercially used sensors. Biomass carbonization by pyrolysis and hydrothermal methods are discussed as a cost-effective strategy for fabrication of electrodes for electrochemical sensing applications. Porosity and surface area along with graphitic nature of bio derived carbon materials greatly affects the performance of electrochemical sensors. Various techniques are used to improve the surface properties so as to enhance the electrocatalytic behavior of working electrodes. Synthetic and bioderived carbon materials are compared for their electrochemical sensing applications.
