Carbon Dots-catalyzed Chemiluminescence for the Determination of Trace Isonaphthol

Abstract: A rapid and sensitive chemiluminescence (CL) method has been found for the determination of isonaphthol. Carbon dots (CDs), synthesized by the ultrasonic method using glucose as carbon precursor, could significantly catalyze the CL reaction between luminol and KMnO4 at extremely low concentrations in an alkaline medium. Moreover, the CL intensity of the CD–luminol–KMnO4 system was further enhanced in the presence of isonaphthol. Based on this finding, a novel CL method for the determination of isonaphthol was … Show more

“…CDs have different preparation methods and numerous sources (including carbohydrates, amino acids, and organic acids) that promote flexible structure modification [26][27][28][29]. In addition, CDs exhibit good electronic transfer ability and can be used to catalyze redox reactions [30][31][32][33] and to establish analysis methods. Long groups [31] prepared CDs with lampblack followed by reduction with 2 of 12 NaBH 4 to form r-CDs, which was then used to catalyze the reaction of hydrogen peroxide with 3,3 ,5,5 -tetramethylbenzidine for hydrogen peroxide detection (detection range: 0.01-0.1 mM).…”

“…[4][5][6][7] With these alluring properties, they have been successfully applied to the fields of bioimaging, cancer therapy, optoelectronics, sensing, photocatalysis, and forensic. [8][9][10][11][12] Mn (VII) with its admirable properties such as low cost, easy handling, and good stability gained abundant attraction as a chemical oxidant in the treatment of pollutants in water and soil. However, this kind of excessive usage can result in the presence of a high amount of Mn (VII) residues in water samples.…”

“…Carbon nanodots (CDs) are considered as promising nanomaterials, because of their prominent physicochemical properties and abundant assembled structure or morphology. With the advance in synthetic technique and clarity of mechanism, CDs reveal their versatility as a luminescent candidate, because of their high photoluminescence quantum yield (PL QY), tunable emission wavelength, good biocompatibility, high photostability, etc. Moreover, the CDs show huge potential applications in several CL reactions, such as lucigenin–H 2 O 2 , luminol–KMnO 4 , and triethylamine–K 2 S 2 O 8 , etc. However, the low luminance of these CL limit their applications and recent efforts rely on the indraft of high-efficiency CL system like peroxalate–H 2 O 2 system to address these issues. To date, most successful approach reported in our prior work is that a proper energy level alignment between the CDs and the energy-rich intermediate produced in the peroxalate–H 2 O 2 reaction can promote the electron transfer between the CDs and the intermediate, resulting in high CL quantum yield (CL QY).…”
