Formation of Flower-Like Self-Assemble Structure by Reaction between Graphene Quantum Dots and Melamine Molecule: Efficient for Electrocatalytic Properties

Covalent framework molecule is very important in modern science due to some potential applications such as gas adsorption, electrode material for catalytic application, metal sensing etc. Structure of covalent molecule is nearly equal to graphene but the optoelectronic properties of graphene are superior to those of covalent molecules because graphene possess different form with diverse application. In this study, a covalent framework molecule was formed in which one element was graphene quantum dots (GQDs) and other was melamine (M). GQDs were selected because GQDs has small size compare to graphene and also it has lots of carboxylic groups by which GQDs can easily assembling with melamine molecules during the coupling reaction and give flower like morphology. The MG shows good electro catalytic activity via two electron transfer process.
