Bisphenol compounds (BPs) have recently been the subject of growing interest due to their wide use in industrial and consumer products. Besides their adverse effects on human endocrine system, effective extraction of BPs and their elimination from complex sample matrix are still significant challenges in food analysis. Herein, a novel Zr(IV)-based metal−organic framework (MOF), named BUT-16, has been synthesized and utilized for the extraction and enrichment of BPs in milk samples. Bisphenol A (BPA), one of the highest production volume BPs, is used as a model molecule. The uptake capacity for BPA can reach up to 48 mg/ g, and the adsorption rate is rapid (∼10 min), because of the larger surface area and cooperation of multiple functionalities of BUT-16. Employing BUT-16 in solid-phase extraction, coupled with ultra-performance liquid chromatography-tandem mass spectrometry detection, we generated a rapid, facile, and robust method for the enrichment and detection of trace BPA and its 12 substitutes in milk samples. After optimization, the limits of detection and quantification for BPs can be achieved as low as 0.05 and 0.2 ng/mL, respectively. Without the correction of the isotopic internal standard, the average recoveries of BPs at the different spiked concentrations varied from 63.8 to 120.6%, with a satisfactory precision (RSD ≤ 8.2%). Furthermore, the proposed method was successfully applied to the detection of BPs in real milk samples, and the results were in accordance with those of methods reported previously.

Hazardous chemical compounds such as endocrine-disrupting chemicals (EDCs) are widespread and part of the materials we use daily. Among these compounds, bisphenol A (BPA) is the most common endocrine-disrupting chemical and is prevalent due to the chemical raw materials used to manufacture thermoplastic polymers, rigid foams, and industrial coatings. General exposure to endocrine-disrupting chemicals constitutes a serious health hazard, especially to reproductive systems, and can lead to transgenerational diseases in adults due to exposure to these chemicals over several years. Thus, it is necessary to develop sensors for early detection of endocrine-disrupting chemicals. In recent years, the use of metal–organic frameworks (MOFs) as sensors for EDCs has been explored due to their distinctive characteristics, such as wide surface area, outstanding chemical fastness, structural tuneability, gas storage, molecular separation, proton conductivity, and catalyst activity, among others which can be modified to sense hazardous environmental pollutants such as EDCs. In order to improve the versatility of MOFs as sensors, semiconductor quantum dots have been introduced into the MOF pores to form metal–organic frameworks/quantum dots composites. These composites possess a large optical absorption coefficient, low toxicity, direct bandgap, formidable sensing capacity, high resistance to change under light and tunable visual qualities by varying the size and compositions, which make them useful for applications as sensors for probing of dangerous and risky environmental contaminants such as EDCs and more. In this review, we explore various synthetic strategies of (MOFs), quantum dots (QDs), and metal–organic framework quantum dots composites (MOFs@QDs) as efficient compounds for the sensing of ecological pollutants, contaminants, and toxicants such as EDCs. We also summarize various compounds or materials used in the detection of BPA as well as the sensing ability and capability of MOFs, QDs, and MOFs@QDs composites that can be used as sensors for EDCs and BPA.

Metal‐organic frameworks (MOFs) are excellent precursors for electrode materials preparations. Synergistic effects may exist between different metal centers in multivariate MOFs, making them often more effective than single‐metal MOFs. Herein, we propose an atom economic mechanochemical method to realize the efficient component regulation of target multivariate MOFs. Moreover, by combining the synthesis of multivariate MOFs and exfoliating MXene, multivariate MOF/MXene composites can be obtained via a one‐step strategy. A further selenization process can derive them into selenides@C/MXene composites. These derived composites contain multiple nanostructured metal selenides embedded in multi‐heteroatom doped carbon matrix. For these composites, abundant heterojunction structures are formed, which can build internal self‐built electric field and effectively enhance the reaction kinetics for sodium‐ion storage. More importantly, the electrochemical performance of NCMS@C/MX composites can be optimized due to the intrinsic characteristics of the containing metal selenides. Overall, experimental results demonstrate the universality of this solvent‐free synthesis route for controllable preparation of high‐performance selenides@C/MXene electrode materials. It provides a feasible and environmentally friendly method to adjust metal ratios for optimal energy storage performance. We hope this research inspires optimization strategies for high‐performance electrode materials and leads to development of energy storage materials with more rational structures and better performance.
