Eletrodos de carbono cerâmico: parâmetros de preparação, propriedades e aplicações como sensores eletroquímicos.

Abstract

The electrodes based on carbon ceramic (CCE) preparation has been improved during last decades, increasing the potential for application of electrodes and electrochemical sensors. The interest on these materials are principally related to their features such as renewable surface, high thermal stability and mechanical strength. This review sets out some of the key aspects related to CCEs, such as the preparation parameters, which directly influence in their electrochemical properties, besides some applications such as electrochemical sensors. Among the preparation factors stand out the precursor characteristic, carbon material type, precursor proportion, catalyst and carbon material. The CCE modification with electron mediator species can broaden the application as electrochemical sensors as increasing the selectivity and sensitivity.
