“…All the chemicals used in this research were of analytical purity and without further purification prior to use. The synthesis of the h-BN was reported in our previous paper [20]. Typically, the foamy precursor was prepared by low temperature combustion synthesis (LCS) method in air in a muffle furnace using H 3 BO 3 , C 6 H 12 O 6 •H 2 O, CO-(NH 2 ) 2 and HNO 3 as raw materials.…”

A novel layered hexagonal boron nitride/titanium dioxide (h-BN/TiO 2) composite photocatalyst has been constructed by anchoring TiO 2 nanoflakes on the surface of h-BN flakes via a solvothermal method. The morphology and dispersion of TiO 2 can be tuned by controlling the amount of flake h-BN. Benefiting from the unique hetero-structure, the photocatalytic performance of the obtained composite toward rhodamine B (RhB) degradation is greatly enhanced, among which 12 wt% h-BN/TiO 2 composites show 3.5 and 6.9 times higher degradation rate than the synthesized TiO 2 and commercial TiO 2 (P25), respectively, and an excellent cycling stability has also been obtained. Moreover, the first-principles calculation reveals the synergetic catalytic effect between TiO 2 and h-BN flake, which is found to be responsible for the significantly enhanced photocatalytic performance of h-BN/TiO 2 composites.

“…Hybridization of h-BN with graphene layers may effectively monitor the bandgap of h-BN or open up of graphene bandgap, which gives rise to a new novel class of semicon-ductor material of hybrid boron carbon nitride (BCN) superlattic interlayered structures [13][14][15][16]. It has been demonstrated that semiconductor materials are most likely to form an electric double layers at the interface between the solid-state electrode and electrolyte solution.…”

A hexagonal boron carbon nitride hybrid (h-BCN) is developed by in situ high-temperature solid-state reaction and subsequent chemical reduction with hydrazine. The XRD and TEM results show that the h-BCN features interlayered structures with two characteristic d-spacing of 0.33 and 0.21 nm. The obtained h-BCN exhibits significant electrochemical sensor for dopamine and uric acid. The cyclic voltammetric and amperometric experiments revealed a good linear relationship between current densities and concentrations of dopamine (DA) of 10-300 μM and uric acid (UA) of 10-500 μM, with high sensitivities of 0.14 μA/μM and 0.32 μA/μM and detection limits of 5 μM and 2 μM, respectively.

“…The GCE has some advantages, such as good stability and conductivity, high rigidity and intensity, and it can be easily modified . In the previous studies, GCE was modified with different materials, such as Mn(III) tetratolylporphyrin chloride (MnTTPCl), Au nanoparticles (AuNPs), multi‐walled carbon nanotubes (MWNTs) and polyethyleneimine (PEI) (AuNPs/MWNTs/PEI), chrysanthemum‐like titanium nitride (CL‐TiN), BaWO 4 nanomaterials, gold nanoparticle‐decorated MoS 2 nanosheets (AuNPs@MoS 2 ), 3,4,9,10‐perylenetetracarboxylic acid (PTCA) and overoxidized dopamine polymer (PDAox), graphene oxide (GO)‐AuNPs, PdPt bimetallic alloy nanowires (PdPt BANWs), Ni(OH) 2 , network‐like carbon nanosheets (NCN), BiVO 4 /FeVO 4 nanocomposite, MoS 2 ‐PANI/rGO, reduced graphene oxide/Prussian blue (PrGO/PB) nanocomposite, and hexagonal boron nitride (h‐BN), for the determination of AA.…”

The electrochemical determination of ascorbic acid was carried out at the surface of glassy carbon electrode (GCE) modified by silver nanoparticles (AgNPs):Polyvinylpyrrolidone (PVP). Nanocomposite was evaluated by fourier transform infrared spectroscopy, zeta potential, and X‐ray diffraction. Also, the surface morphologies of the developed electrode were investigated by scanning electron microscopy, and profilometer. The electrochemical performance of AgNPs/PVP/GCE was studied with cyclic voltammetry and electrochemical impedance spectroscopy measurements. The electrochemical studies demonstrated that the electrode had a large surface. Compared with the bare GCE, PVP/GCE, and AgNPs/GCE, the AgNPs/PVP‐modified GCE showed excellent performance for the electrochemical determination of ascorbic acid. At the optimized conditions of differential pulse voltammetry in pH 6.0 of phosphate buffer solution, the modified electrode allowed the determination of ascorbic acid on a potential of 0.54 V vs. Ag/AgCl. Under optimized conditions, the low detection limit of 0.047 μM and working range of 0.2‐1200 μM were obtained at the AgNPs/PVP/GCE. The AgNPs/PVP/GCE allowed to obtain highest peak current values at low concentrations. Moreover, the fabricated electrode also exhibited good repeatability, reproducibility, and stability. The developed electrode was successfully enforced for the analysis of ascorbic acid in banana, kiwi fruit, mango, and pineapple.
