Degradation of acid blue 41 with carbon quantum dots@MOF-808 nanocomposite as a biocompatible photocatalyst under visible light
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.
期刊介绍：
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
