Metal-Doped Graphene Materials as Electrocatalysts in Sensors

Abstract

<div>A wide range of new electrocatalytic nanomaterials are introduced from time</div><div>to time and are expected to continuously develop and advance the electrocatalytic</div><div>sensors for different molecules. This book chapter intends to cover the latest progress</div><div>and innovations in the field of metal-doped graphene (MDG) based electrocatalysts as</div><div>sensors. In addition to experimental studies, electrocatalytic sensor behavior of</div><div>bioactive molecules using theoretical studies has become one of the most rapidly</div><div>developing fields. It is readily evident that metals combined with graphene, doped with</div><div>single transition metal atom catalysts, and prepared as electrocatalytic sensors can be</div><div>employed to enhance some unique properties different from the properties of bulk</div><div>graphene. This book chapter encompasses preparation techniques of MDG materials as</div><div>sensors for the detection of H2, NO2, H2O2, CO, CO2, SO2, O2, and H2S from</div><div>experimental and theoretical perspectives. In this respect, we present a synthesis of</div><div>MDG based electrocatalysts and factors affecting sensors using both experimental and</div><div>theoretical studies. The most probable reason for the highest efficiency of some metals</div><div>doped graphene is described from the experimental and theoretical perspectives.</div><div>Finally, the conclusion describing challenges and future outlooks for the advancement</div><div>of MDG materials is also given. </div>
