“…Sensing heavy metals such as Hg 2+ , Co 2+ , Cr 3+ , Cu 2+ , Ca 2+ , Mn 2+ , Fe 3+ , and Pb 2+ can be realized with MoS 2 -based FETs since these metal ions can bind to the point defects and S atoms in the MoS 2 crystal lattice and result in the change of electrical conductivity. , Nevertheless, 2D TMDs-based ion sensors usually do not have detection selectivity to a specific ion over the others . Therefore, grafting specific receptors on TMD nanosheets has been an effective method to achieve selective detection.…”

Two-dimensional (2D) transition metal dichalcogenides (TMDs) with layered crystal structures have been attracting enormous research interest for their atomic thickness, mechanical flexibility, and excellent electronic/optoelectronic properties for applications in diverse technological areas. Solution-processable 2D TMD inks are promising for large-scale production of functional thin films at an affordable cost, using highthroughput solution-based processing techniques such as printing and roll-to-roll fabrications. This paper provides a comprehensive review of the chemical synthesis of solution-processable and printable 2D TMD ink materials and the subsequent assembly into thin films for diverse applications. We start with the chemical principles and protocols of various synthesis methods for 2D TMD nanosheet crystals in the solution phase. The solution-based techniques for depositing ink materials into solid-state thin films are discussed. Then, we review the applications of these solution-processable thin films in diverse technological areas including electronics, optoelectronics, and others. To conclude, a summary of the key scientific/technical challenges and future research opportunities of solution-processable TMD inks is provided.

In this paper, a porous zirconium‐based metal–organic framework (NH2‐UiO‐66) and functionalized carbon black (FCB) composite was prepared through a one‐pot hydrothermal method, and a novel electrochemical sensor based on NH2‐UiO‐66@FCB modified glassy carbon electrode (NH2‐UIO‐66@FCB/GCE) was developed for the simultaneous sensoring of butylhydroxyanisole (BHA) and tert‐butylhydroquinone (TBHQ). The morphology and structure of NH2‐UiO‐66@FCB were characterized through scanning electron microscopy, X‐ray diffraction, Fourier transform infrared spectroscopy, and X‐ray photoelectron spectrum. The electrochemical behaviors of the NH2‐UiO‐66@FCB/GCE were investigated using cyclic voltammetry, differential pulse voltammetry, and electrochemical impedance spectroscopy. Under optimized experimental conditions, the linear ranges for TBHQ and BHA detection were determined to be 0.12–460 μM and 0.7–420 μM, respectively, with their corresponding detection limits of 0.072 μM and 0.29 μM. Furthermore, the sensor exhibited excellent selectivity, repeatability and stability, and successfully used for the simultaneous detection of TBHQ and BHA in food samples.
