3D Graphene: A Nanocarbon Innovation in Electrochemical Sensor Technology

چکیده مقاله

Nanocarbons, a diverse category of nanoscale carbon materials, have transformed scientific and industrial fields. Graphene, a remarkable nanocarbon, stands out due to its exceptional mechanical, electrical, and thermal properties. Three-dimensional (3D) graphene, with greater surface area and conductivity than its 2D counterpart, has gained recent popularity. In electrochemical sensing, the key component is the electrochemical electrode, driving chemical reduction reactions and generating signals. 3D graphene-based structures, featuring tailored meso- and micropores, offer interconnected hierarchical architectures, high surface area, intrinsic electrical conductivity, and a high signal-to-noise ratio, making them ideal electrochemical sensors. Two main fabrication strategies produce 3D graphene: 3D graphene aerogels and 3D graphene foams, each suited for different applications. Graphene foam's …
