Herein, we reported a octahedral Cd3(C3N3S3)2 coordination polymer as a new noble metal-free photocatalyst for robust photocatalytic H2O2 production from methanol/water solution. The coordination polymer can give an unprecedented H2O2 yield of ca. 110.0 mmol • L−1 • g−1 at pH = 2.8 under visible light illumination. The characterization results clearly revealed that the photocatalytic H2O2 production proceeds by a pathway of two-electron reduction of O2 on the catalyst surface. This work showed the potential perspective of Mx(C3N3S3)y (M = transitional metals) coordination polymers as a series of new materials for solar energy storage and conversion.

“…Besides, the study of mechanisms of CL in aqueous system has made great progress in recent years [151], such as expounding the mechanisms of quantum-dot (QDs)-enhanced CL [4]. However, the mechanisms of the luminescence of analytes in CTL are still not fully understood and comprehensive insight is clearly necessary.…”

“…Thus, various chemiluminescence (CL) systems have received considerable attention in the past years. To further improve the sensitivity of CL assays, various catalysts have been investigated, including metal nanoclusters [1], metallic nanoparticles (in particular noble metal nanoparticles) [5,6], metal oxide nanoparticles [7,8], carbon dots [9][10][11], layered double hydroxide (LDH) [4,12], quantum dots [13,14], and LDH-quantum dot nanocomposites [15].…”

MIL-53(Fe) MOF-mediated catalytic chemiluminescence for sensitive detection of glucose

et al. 2016

Various analytical applications of metal-organic frameworks (MOFs) have been rapidly developed in the past few years. However, the employment of MOFs as catalysts in chemiluminescence (CL) analysis is rare. Here, for the first time, we found that MIL-53(Fe) MOFs could significantly enhance the CL of luminol in the presence of HO in an alkaline medium. The CL intensity in the luminol-HO-MIL-53(Fe) system was about 20 times higher than that in the luminol-HO system. Moreover, the XRD pattern of MIL-53(Fe) after CL reaction was almost the same as that of the original MIL-53(Fe), confirming the catalytic role of MIL-53(Fe) in the luminol-HO-MIL-53(Fe) system. The possible mechanism behind the enhancing phenomenon was discussed based on the results from the CL spectra, FL probe experiments, and active oxygen species measurements. By coupling with the glucose oxidase-based catalytic oxidation reaction, a sensitive and selective CL method was developed for the detection of glucose. There is a linear relationship between the logarithm of CL intensity and the logarithm of glucose concentration in the range from 0.1 to 10 μM, and a detection limit of 0.05 μM (S/N = 3) is obtained. The proposed method has been applied to the determination of glucose in human serum samples with satisfactory results. Graphical abstract MIL-53(Fe) MOFs are found to greatly enhance the chemiluminescence emission of the luminol-HO system, and this finding resulted in a new chemiluminescence method for biosensing of glucose when coupled with the glucose oxidase.
