“…4 shows the infrared spectrum curve of the NixCo1-x-O (x ≤ 0.5) sample. It can be seen that the IR spectra of all samples are similar, in which the peaks at 570 and 661 cm -1 correspond to the vibration of the Co-O bond in the sample [6] , which can indicate that the Co in the sample is oxidized to CoO, which also verifies the results of the XRD analysis part.…”

Zeolitic imidazolate frameworks (ZIFs) have attracted extensive research interests because of their porosity, large specific area, and adjustable aperture. In particular, a series of nanomaterials derived from ZIF-67 precursor has broad application prospects in energy and environment. In this paper, Co-ZIF nanocrystal was synthesized by solvothermal method, by introducing a second kind of transition metal Ni, the NixCo1-x-ZIF nanocrystals with single metal Co-ZIF structure were synthesized. NixCo1-x-O composites were obtained by oxidation of NixCo1-x-ZIF nanocrystals, and the electrocatalytic hydrogen evolution activity of composites modified glassy carbon electrode in 1 M KOH solution was tested. It is found that the Ni0.5Co0.5-O composites have the lowest overpotential compared with similar composites.

“…In recent years, fluorescence-based detection methods have gradually attracted the attention of many researchers due to their high detection sensitivity, low cost, and ease of in situ and real-time detection. Many fluorescent materials, such as organic molecules, − quantum dots, and metal–organic frameworks (MOFs), − have been designed and developed for the fluorescence detection of methylmercury. Amrita Chatterjee et al developed a cost-effective aggregation-induced emission (AIE) active fluorescent chemical dosimeter for methylmercury detection .…”

Methylmercury (CH3Hg+) recognition remains a challenging and imperative task due to its high toxicity and wide existence in the ecosystem. Herein, a novel fluorescent covalent–organic framework containing a boric acid functional group (COF-BA) was prepared by a postmodification strategy for CH3Hg+ detection. COF-BA served as a sensing platform for CH3Hg+ with fluorescence static quenching accompanied by fluorescence color changing from intense blue to colorless, and the detection limit was determined as 1.68 μM in a relatively narrow concentration range. COF-BA also exhibited superior selectivity toward CH3Hg+ detection. Furthermore, the spiked and recovery test in real water samples showed its efficient detection practicality. The detection mechanism of COF-BA toward CH3Hg+ was investigated. The recognitive boric acid group in COF-BA was first replaced by CH3Hg+. Then, the quinoline structure that served to limit the rotation of the imine bond was disrupted, leading to dramatic fluorescence quenching. The boric acid functional COF fluorescent probe can be a promising sensing platform for the detection of methylmercury and also provides new ideas for the construction of new fluorescent COF materials.

“…Sensor arrays, mimicking the animal gustatory system, have attracted wide attention due to their convenient construction and multitarget response characteristics, and many studies have been carried out for environmental monitoring and life analysis. − The sensor array is composed of different sensor units, which achieve the qualitative and quantitative of multiple targets simultaneously through the wide response and cross response of each unit to different targets. Compared with the single-target probe, the sensor array reduces the high requirement for specificity and greatly improves the success rate of probe design. − Particularly, the simultaneous quantification of multiple antibiotics in complex environmental samples by sensor array not only significantly improves the detection efficiency but also facilitates the application of antibiotic traceability and in situ environmental chemical effect analysis.…”

The classes and forms of antibiotics directly determine their ecotoxicity and environmental chemical behavior, and developing a sensor array for simultaneous and in situ detection of antibiotics is highly anticipated. In this study, different morphologies of g-C 3 N 4 with different fluorescence properties and peroxidase activity were prepared by regulating the degree of interlayer stacking and planar connectivity. Subsequently, in order to enhance its enzyme activity and amplify the differences in response signals to different antibiotics, three morphologies of g-C 3 N 4 /MIL-101(Fe) were prepared by in situ growth of equivalent amounts of MIL-101(Fe) on g-C 3 N 4 , respectively. The sensor array constructed based on the cross-response signals between g-C 3 N 4 /MIL-101(Fe) and antibiotics not only realized the simultaneous detection of quinolones, furans, tetracyclines, and lincomamides but also could efficiently identify their seven different forms. In the range of 0.2−0.8 ppm, the minimum detection limit for antibiotics was 12 ppb. In addition, the recovery experiments of multicomponent-mixed antibiotics in environmental samples show that the recovery rate remained at 91.42− 107.59%, confirming the reliability and practicality of the sensor array. This study not only revealed the influence of crystal morphology regulation on the optical properties and enzyme activities of nanozymes, but also provided support for tracing, ecological remediation, and in situ environmental chemical behavior research of antibiotics.
