“…The characteristic peaks of PANI at 3088–3258 cm −1 were attributable to the stretching of N–H [ 31 , 32 , 33 ], and the peaks at 1643–1546 cm −1 and 1472–1506 cm −1 were due to the C=N and C=C stretching modes for the quinoid and benzenoid rings [ 32 , 33 , 34 ], respectively. The bands at about 1304 cm −1 and 1243 cm −1 corresponded to the stretching of C–N bonds in the benzenoid ring, whereas the bands between 1000 and 1129 cm −1 were assigned to a planar vibrational flexion of C–H bonds [ 32 , 33 , 34 ]. The band at 803 cm −1 represented the stretching of C–H out-of-plane bending vibration [ 31 ].…”

A comparative study was performed in order to analyze the effect of metal oxide (MO) on the properties of a polymeric matrix. In this study, polyaniline (PANI)@Al2O3, PANI@TiC, and PANI@TiO2 nanocomposites were synthesized using in situ polymerization with ammonium persulfate as an oxidant. The prepared materials were characterized by various analytical methods such as X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), thermogravimetric analysis (TGA), UV/visible (UV/Vis) spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM). Furthermore, the conductive properties of the materials were tested using the four-point probe method. The presence of MO in the final product was confirmed by XPS, XRD, FTIR, and TEM, while spectroscopic characterization revealed interactions between the MOs and PANI. The results showed that the thermal stability was improved when the MO was incorporated into the polymeric matrix. Moreover, the results revealed that incorporating TiO2 into the PANI matrix improves the optical bandgap of the nanocomposite and decreases electrical conductivity compared to other conducting materials. Furthermore, the electrochemical properties of the hybrid nanocomposites were tested by cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD). The obtained results suggest that the PANI@TiO2 nanocomposite could be a promising electrode material candidate for high-performance supercapacitor applications.

In the present paper, we report the phenomena of the formation of the novel composite nanostructures based on TiO 2 nanotubes (NTs) over-grown by thin boron-doped diamond (BDD) film produced in Microwave Plasma Enhanced Chemical Vapor Deposition (PE MWCVD). The TiO 2 nanotube array overgrown by boron-doped diamond immersed in 0.1 M NaNO 3 can deliver high specific capacitance of 7.46 mF cm −2 . The composite electrodes were characterized by scanning electron microscopy (SEM), Raman spectroscopy, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) techniques. The depth-resolved investigations reveal that the primary anatase structure of TiO 2 NTs was partially transformed into Ti 2 O 3 and non-stoichiometric TiC fractions. The explanation for this effect is the decomposing of TiO 2 NTs in the presence of activated hydrogen and carbon in the plasma leading to enhanced dehydration of NTs and carbon bonding originating from dissociated methane. This phenomena description fits also to processes demonstrated at hydrogenated TiO 2 (H-TiO 2 ) nanotube arrays used as electrode material for supercapacitors. Nevertheless, the increase of electrochemical performance can be attributed to several reasons: (1) the unique morphology of titania nanotubes and columnar BDD with intergrain defects and valley increasing specific area of electrode and (2) presence of TiC and Ti 2 O 3 fractions introducing additional capacitance.Nowadays, the world is directed towards green energy and its efficient storage. Supercapacitors are notably useful due to the highly reversible charge storage process, long cycle-life and ability of rapid charging and discharging. 1 Presently, the supercapacitors are divided into two main types: electrical double layer capacitors (EDLC) 2 and redox supercapacitors (pseudocapacitors), followed by Faradic reactions carried out at the electrode material. 3 Moreover, they can store substantially more energy than conventional capacitors due to the very small distance of charge separation in the electrical double layer and highly extended surface area of electrode material. 4 EDLC provide far larger charging and discharging times than typical capacitors or batteries up to 10 −6 s, charge/discharge efficiency close to ∼100% and nearly infinite cycle-life. 4 The titania nanotubes provide a large specific surface area, a direct pathway of charge transport but the specific capacitances are generally limited to less than 1 mF cm −2 without intentional doping or treatment. Lu and Li et al. 5,6 reported that hydrogenated TiO 2 by heating in hydrogen atmosphere resulted in an improvement of specific capacitance up to 3.24 mF cm −2 . Moreover, Wang and Leshuk et al. 7,8 received similar hydrogenated TiO 2 under hydrogen plasma treatment.Recently, there is interest in synthesis of a different type of titania/carbon composite materials such as nanotubes, 9-12 and porous titanium carbides 13,14 which showed the enhanced effectiveness of those materials in photocatalysis, 15 electrochemical biosensing, 16 photolum...

The novel gel composite, based on the ground o f i o n i c l i q u i d ( 1 -b u t y l -3 -m e t h y l i m i d a z o l i u m hexafluorophosphate, BMIMPF 6 ) and titanium carbide (TiC) nanoparticles, was used to modify glassy carbon electrode and applied to the electrochemical determination of tryptophan (trp). The physical and electrochemical characterizations of the BMIMPF 6 -TiC gel modified electrode were studied in detail by scanning electron microscopy, energy dispersive X-ray spectroscopy, cyclic voltammetry, and differential pulse voltammetry methods. Due to the large specific surface area and strong adsorption property of TiC nanoparticles, as well as the good ionic conductivity and strong electrocatalytic property of BMIMPF 6 , the oxidation peak current of trp at BMIMPF 6 -TiC gel modified electrode showed good linear relation with its concentrations ranging from 0.50 to 30 μmol/L and 30 to 500 μmol/L, respectively. The detection limit was 0.053 μmol/L. More importantly, the BMIMPF 6 -TiC gel modified electrode had good antiinterference ability and can be successfully applied in the electrochemical determination of trp in real food samples.
