Solar-light-induced green conversion of amines into imines by lemon derived heteroatoms-doped GQDs as a green photocatalyst

Graphene is one of the amazing present encroachments in current research area of science and one of the utmost fascinating materials for relevance in cutting-edge research. Herein, we designed lemon-derived heteroatoms-doped graphene quantum dots (S, N-GQDs) based photocatalyst for the first time. For the integrating reactions of amines in aerobic conditions under solar light by S, N-GQDs photocatalyst exhibit utmost higher photocatalytic activity than simple oxygen-doped graphene quantum dots (O-GQDs) due to slow recombination charges. The mechanisms accountable for the drastically increased photocatalytic activity of S, N-GQDs in solar light responsive integrating reactions of amines in aerobic conditions into the corresponding derivative of imines are also completely scrutinized.
