Abstract
Electrochemical sensing performance of two-dimensional hexagonal boron nitride (2D h-BN) has traditionally been suppressed by their intrinsic electrical insulation and deficient electron transportation mechanism. However, the excellent electrocatalytic activity, high specific surface area, N- and B- active edges, structural defects, adjustable band gap through interaction with other nanomaterials, and chemical functionalization, makes 2D h-BN ideal for many sensing applications. Therefore, finding a pathway to modulate the electronic properties of 2D h-BN while the intrinsic characteristics are well preserved, will evolve a new generation of highly sensitive and selective electrochemical (bio)sensors. That is why extensive research has recently focused on the challenge to functionalize 2D h-BN by controlling the surface chemical reactions with external species, particularly metal nanoparticles. This review summarizes the most recent progress in the application of 2D h-BN nanosheets in electrochemical (bio)sensing. We will explore the fabrication techniques of 2D h-BN for electrochemical applications followed by thorough discussion on their advantages, shortcomings, and promising possibilities as (bio)sensing platforms in near future.

Abstract Providing a good contact between electroactive materials and their substrates is an important factor for developing supercapacitors. In our work, a Graphene (Gr)/cuprous oxide (Cu2O) nanocomposite film was directly fabricated on a Cu foil by a simple one-step electrodeposition approach. The obtained binder-free electrode (referred as Gr-Cu2O nanocomposite/Cu foil) was directly used as a working electrode for supercapacitors. The electrochemical evaluations in 6 M KOH show that the elect...

Abstract In this study, a novel electrochemical method as a conductive voltammetric sensor for determination of N-hydroxysuccinimide was developed. The N-hydroxysuccinimide sensor was achieved by carbon paste electrode (CPE) amplified with tri-component nanohybrid composite (Platinum nanoparticle/Polyoxometalate/Two-dimensional hexagonal boron nitride nanosheets) (PtNPs/POM/2D-hBN) and 1-hexyl-3-methylimidazolium chloride (HMICl) as conductive mediators. A significant decrease (110 mV) in the ox...

Abstract A new electrochemical sensor has been developed for the simultaneous determination of 4-aminophenol (4-AP) and phenol (Ph) based on the defect-rich hexagonal boron nitride (D-h-BN). The D-h-BN was prepared via one-step calcination route using a single-source precursor. The obtained D-h-BN was structurally characterized by X-ray diffraction (XRD), fourier transform infrared (FTIR) spectroscopy and transmission electron microscopy (TEM). Photoluminescent (PL) result suggested that the as-...

Abstract Promising properties of boron nitride nanomaterials such as their chemical, thermal, and mechanical stability have made them suitable materials in a various range of applications. However, their low electrical conductivity and wide bandgap, particularly in the case of boron nitride quantum dots (BNQDs), have given rise to severe limitations. Efforts on bandgap engineering through doping and surface functionalization have gained little success due to their high thermodynamic stability an...

Abstract A novel graphene (Gr)/Co3O4/polypyrrole (PPy) ternary nanocomposite (GCP) was synthesized by a two-step technique in which the surface of Gr/Co3O4 binary nanocomposite (GC) was covered by a conductive thin film of PPy. First, Co3O4 anchoring nanoparticles were embedded into graphene sheets by a chemical precipitation method, and then covered by a PPy thin film via in-situ polymerization. The fabricated nanocomposites were cast on the Cu/Cu(OH)2 substrates prepared by soaking in an alkal...

Two-dimensional hexagonal boron nitride (h-BN) as a graphene-like material was investigated due to its impending applications in electronics. The h-BN band gap Eg as an important factor and its variation between bilayer ZrSe2 sheets were explored under an external electric field. The initially indirect band gap is found to convert to direct band gap by means of density functional theory. Additionally, the band gap is modulated by van der Waals corrections from 0.21220 to 0.01770 eV. Based on the...

2D transition metal carbides and nitrides (MXenes) open up novel opportunities in gas sensing with high sensitivity at room temperature. Herein, 2D Mo2 CTx flakes with high aspect ratio are successfully synthesized. The chemiresistive effect in a sub-µm MXene multilayer for different organic vapors and humidity at 101 -104 ppm in dry air is studied. Reasonably, the low-noise resistance signal allows the detection of H2 O down to 10 ppm. Moreover, humidity suppresses the response of Mo2 CTx to or...

Abstract A single-step thermochemical synthesis route for boron carbon nitride (BCN) has been reported in this work. X-ray photoelectron spectroscopy (XPS) shows that B, C, and N atoms are atomically intermixed with the dominance of graphite and BN domains. In Fourier transform infrared spectroscopy, a broad band at 1521 cm-1 (sp2 C-N) indicates the presence of defect states comparable to the presence of πP (C-N) plasmon loss peak in XPS. The role of defect states in the optical properties of BC...

Hybrid flexible bioelectronic systems refer to integrated soft biosensing platforms with tremendous clinical impact. In this new paradigm, electrical systems can stretch and deform with the skin while previously hidden physiological signals can be continuously recorded. However, hybrid flexible bioelectronics will not receive wide clinical adoption until these systems can be manufactured at industrial scales cost-effectively. Therefore, new manufacturing approaches must be discovered and studied...

Abstract Graphene (Gr)/metal oxide nanocomposites, as advanced electrode materials, have drawn significant attention in supercapacitors due to their two components' synergistic cooperation, which compensates each other's drawbacks and hence perform better than their individual components. In this study, two graphene/metal oxide nanocomposites, Gr/NiO and Gr/Co3O4 binaries were separately synthesized by a co-precipitation method in which NiO or Co3O4 as interlayer spacers were inserted into the g...
