2.1 Introduction
The unique ability of carbon atoms to participate in robust covalent bonds with each other and also with other elements in diverse hybridization states (sp, sp2 , sp3 ) allows them to form a wide range of structures, from small molecules to nanomaterials [1]. Carbon‐based nanomaterials have garnered a great deal of interest over the past three decades, starting with the debut of fullerene in 1985 [2], followed by carbon nanotubes [3] (CNTs) and graphene [4] in 1991 and 2004, respectively. Fullerene, CNTs, and graphene are primarily composed of sp2 carbon atoms with a network of conjugated π electrons. In recent years, carbon dots (CDs) with mixed sp2 and sp3 carbon atoms plus defects and heteroatoms, as well as nanodiamonds consisting of sp3 carbon atoms, have also received a great deal of attention [5, 6]. Due to the quantum confinement effect, these carbon nanomaterials (CNMs) possess many interesting physicochemical properties that are not attainable in bulk carbon materials like diamond and graphite [7, 8].
