Abstract
CQDs@MOF-808 guest@host nanocomposite as a biocompatible photocatalyst has been synthesized using a ship-bottle approach involving the impregnation method for immobilization of glucose molecules as carbon quantum dots (CQDs) precursor into the MOF-808 pores to form Glucose@MOF-808 and further fabrication of carbon quantum dots (CQDs) via in-situ thermolysis route of glucose molecules loaded into the pores of MOF-808. The photocatalytic degradation efficiency of 86.62 % was calculated for CQDs@MOF-808 nanocomposite for degradation of Acid Blue 41 in 120 min under visible light irradiation, that was attributed to the presence of CQDs inside MOF-808 pores. The exceptional characteristics of CQDs include outstanding up-converted photoluminescence (UCPL) effects, photo-induced electron transfer, electron reservoir properties, and electron-hole separations, all contributing to the photocatalytic degradation of Acid Blue 41. The synthesized samples were characterized by PXRD, FT-IR, EDX, N2 adsorption–desorption isotherm, TEM, DRS, PL, EIS and Mott − Sckottky measurements.
