“…This is not surprising due to their interesting electronic and physiochemical properties, combined with a high surface area and impressive electrical conductivity. Consequently, they are finding increasing applications in electrochemical-based systems, including sensors , and energy storage devices. , They are readily functionalized with groups, such as −OH and −COOH, which in turn can provide active or coordination sites that can be exploited in the development of sensing materials. , Another attractive property is their ability to form composites or hybrids with other materials giving new hybrids that exhibit synergetic effects …”
