Abstract ：
The photocatalytic degradation of dyes by graphitic carbon nitrides (g-C3N4) under sunlight has received increased attention. However, the fast recombination of charge carriers still restricts its photocatalytic application. To overcome this drawback, a g-C3N4/Mn3O4/ZIF-8 (CMZ) composite was prepared to activate peroxymonosulfate (PMS)-based advanced oxidation processes for degradation of rhodamine B (RhB) in water. Under visible light, the catalysts exhibited high activity and stability in activating PMS to generate radicals ((OH)-O-center dot, O-center dot(2)- and SO4 center dot-) and the maximum RhB degradation of approximately 94.34 % was achieved. The RhB degradation followed first-order kinetics and the rate constant of g-C3N4/Mn3O4/ZIF-8/PMS system was 2.85, 3.09, 9.82 and 17 times of g-C3N4, Mn3O4, ZIF-8 and PMS, respectively. Moreover, the synergistic effect of CMZ and PMS on the removal efficiencies of total organic carbon (TOC) for RhB and wastewater were 92.84 % and 96.13 %, respectively. After five cycles of use, the degradation rate of the prepared catalyst for RhB only decreased by 1.7 %. This work provided new insights that the synergistic effect of advanced oxidation technologies and photocatalysis holds broad prospects for the photodegradation of RhB.

Abstract ：
To improve the photocatalytic performance of carbon nitride (g-C3N4), a flower-shaped COCN/ZIS composite was synthesized by growing ZnIn2S4 (ZIS) onto structurally defective g-C3N4 (COCN) nanosheets. The experimental results indicate that the prepared photocatalyst has excellent photocatalytic performance for the degradation of methylene blue (MB), with an apparent rate constant of 0.0661 min−1, which is approximately 6.89, 6.06 and 7.39 times greater than that of g-C3N4 (0.0096 min−1), COCN (0.01091 min−1) and ZIS (0.00895 min−1), separately. The improvement in the photocatalytic performance of COCN/ZIS can be attributed to the defect structure of COCN and the well-matched relationship between COCN and ZIS, both of which result in valid photoinduced charge separation and migration. This has also been confirmed by the synergy coefficient (3.33). Furthermore, the total organic carbon content (TOC) removal rates of MB and wastewater by the 60-COCN/ZIS composite were 85.96 % and 75.32 %, respectively, suggesting that the resultant catalyst has potential application in the photodegradation treatment of MB. Finally, the capture experiments and electron paramagnetic resonance analysis show that ·OH, ·O2– and h+ species are generated during the process, among which ·OH plays a great part in the photodegradation of MB by the COCN/ZIS compound. © 2024 Elsevier B.V.

Abstract ：
As the reliable biomarkers to evaluate the diabetes and neurological disease, sensitive and accurate detection of glucose and glutathione (GSH) in biological samples is necessary for early precaution and diagnosis of relateddiseases. The single red upconversion nanoparticles (UCNPs) especially with core-shell structure can penetrate deeper biological tissues and cause less energy loss and thus have higher sensitivity and accuracy. Additionally, an enzyme-controlled cascade signal amplification (ECSAm) strategy will further enhance sensitivity. Herein, using single red UCNPs with core-shell structure as the luminescent material, a fluorescent sensor based on ECSAm was developed for the highly sensitive and accurate detection of glucose and GSH. Under the optimal conditions, the limits of detection for glucose and GSH by fluorescent method were 0.03 mu M and 0.075 mu M, separately. This assay was used to analyze the content of glucose and GSH in serum samples, and the obtained data was close to that of commercial blood glucose and GSH detection kit. The developed sensor platform based on single red UCNPs with core-shell structure and ECSAm can be a promising method for the accurate and sensitive detection of glucose and GSH in biological samples.

Abstract ：
Ascorbic acid (AA) and alkaline phosphatase (ALP) in human serum are indispensable substances in the process of biological metabolism, and their abnormal contents are strongly associated with a range of diseases. Therefore, it is meaningful to develop a simple, accurate and sensitive assay for the detection of AA and ALP. Up-conversion nanoparticles (UCNPs) have some unique characteristics, especially, the potential for background-free excitation by the near-infrared region (NIR) significantly improves the limits of detection (LODs). Moreover, sensors based on the inner filter effect (IFE) do not require covalent linkage between receptors and fluorophores or surface modification, thus the probe fabrication is simple and flexible UCNP-based. Therefore, a simple, selective, sensitive, and flexible sensing system for the detection of AA and ALP is proposed by combining the IFE and the cyclic signal amplification strategy. Under ideal circumstances, the LODs of ALP through the colorimetric and fluorescence method were 0.192 U/L and 0.013 U/L. The established sensing platform was applied to assessing ALP activity in human serum, and the detection results are close to those of commercially available kits, indicating its immense potential as an effective and convenient tool for monitoring ALP activity in clinical settings.

Abstract ：
Three dimensions (3D) flower-shaped g-C3N4/MoS2 composite was prepared by immobilizing molybdenum di-sulfide (MoS2) on carbon nitride (C3N4) with structural defects by in-situ hydrothermal assay. The morphological structure and photochemical properties of the obtained catalysts were characterized by SEM, TEM, EDS, FTIR, XRD and XPS. Using methylene blue (MB) as the target pollutant, the photocatalytic performance cyclic stability of g-C3N4/MoS2 composite were studied under simulated sunlight. The results showed that the prepared catalyst could remove 98 % of MB within 60 min and still reached 96.4 % after 5 cycles with good stability and regeneration. Its apparent rate constant was 0.0523 min-1, which was 11.5, 8.2 and 13.9 times higher than those of g-C3N4 (0.00453 min-1), C3N4 with structural defects (0.00635 min-1) and MoS2 (0.00377 min-1), indicating that the synergistic effect of structural defects, heterojunctions and 3D structure has achieved efficient degradation of MB. Furthermore, the photocatalytic mechanism of g-C3N4/MoS2 composite was proposed by combining free radical capture experiment and electron paramagnetic resonance (EPR) spectroscopy and the results showed that that center dot OH and center dot O2- played a primary role in the catalytic degradation.

Abstract ：
The AgNPs@NCN composite was prepared by loading silver nanoparticles (AgNPs) onto the surface of carbon nitride (g-C3N4) with nitrogen-vacancy and cyanide defect and used for the synergistic degradation of methylene blue (MB) by the structural defect of g-C3N4, the surface plasmon resonance of AgNPs and Schottky barrier formed between them. The morphology, structure, chemical composition and photoelectrochemical properties were characterized by SEM, TEM, FTIR, XRD, XPS, BET and UV-Vis. The effects of different loads of AgNPs on photocatalytic performance were investigated and the results showed 10%AgNPs@NCN exhibited good photodegradation performance. The maximum degradation efficiency of MB by 10%AgNPs@NCN reached 100% with the rate constant of 0.05443 min-1, which was 9.15 and 6.89 times higher than those of g-C3N4 (0.00595 min-1) and NCN (0.0079 min-1), respectively. The mineralization degree of organic pollutants was evaluated by total organic carbon (TOC) and the results showed that the TOC removals of 10%AgNPs@NCN photocatalytic reaction were 77% and 93% for MB and wastewater, respectively. After four cycles of photocatalytic degradation experiments, the degradation rate of MB was still more than 98.2% and there was no significant change in the characteristic stretching of the catalyst, indicating that the prepared photocatalyst had good stability and reusability.

Abstract ：
A novel hybrid material (ZIF-7-NH2@MIP) combining high adsorption capacity of amino-functional zeolitic imidazolate framework and specific recognition ability of dual-template molecular imprinted polymer was synthesized. The prepared ZIF-7-NH2@MIP was characterized by a range of instrumental techniques and combined with high performance liquid chromatography for the detection of four phthalate esters. The limits of detection of the four PAEs were below the maximum residue limit of GB 3838-2002 in China, ranging from 0.04 to 0.08 mu g L-1. The recoveries of the three real samples of mineral water, carbonated drinks and pulpy juices spiked at 10 mu g L-1 were 88.68-98.58% and the relative standard deviations was 1.19-3.40%. The above results showed that the obtained absorbent exhibited many advantages for extracting analytes in aqueous solution especially complex environment due to the combination of the superior hydrothermal and large specific surface area of the amino-functionalized ZIF-7-NH2 and the specific identification of the dual-template molecular imprinted polymer.
