“…The use of PB as a recognition element for H 2 O 2 detection is extensive [ 14 , 15 , 16 ]. Furthermore, in order to increase the sensitivity and the rapid response of electrochemical sensors, nanomaterials and nanostructured systems are used to modify the electrode surface, since it has been reported that nanomaterials promote electron transfer more efficiently between the electrodes [ 6 , 7 , 8 , 11 , 17 , 18 , 19 ]. On the other hand, carbon nanotubes possess interesting chemical and physical properties, which are useful in order to modify electrochemical sensors, therefore, the combination of PB, carbon nanotubes (CNTs), and metals have received special attention.…”

In this work, a new hydrogen peroxide (H2O2) electrochemical sensor was fabricated. Prussian blue (PB) was electrodeposited on a glassy carbon (GC) electrode modified with zirconia doped functionalized carbon nanotubes (ZrO2-fCNTs), (PB/ZrO2-fCNTs/GC). The morphology and structure of the nanostructured system were characterized by scanning and transmission electron microscopy (TEM), atomic force microscopy (AFM), specific surface area, X-ray diffraction (XRD), thermogravimetric analysis (TGA), Raman and Fourier transform infrared (FTIR) spectroscopy. The electrochemical properties were studied by cyclic voltammetry (CV) and chronoamperometry (CA). Zirconia nanocrystallites (6.6 ± 1.8 nm) with cubic crystal structure were directly synthesized on the fCNTs walls, obtaining a well dispersed distribution with a high surface area. The experimental results indicate that the ZrO2-fCNTs nanostructured system exhibits good electrochemical properties and could be tunable by enhancing the modification conditions and method of synthesis. The fabricated sensor could be used to efficiently detect H2O2, presenting a good linear relationship between the H2O2 concentration and the peak current, with quantification limit (LQ) of the 10.91 μmol·L−1 and detection limit (LD) of 3.5913 μmol·L−1.

In this theoretical work, the encapsulation effect of bithiophene (2T) inside single‐walled carbon nanotubes (SWCNTs) is reported. The optimum configurations of 2T inside SWCNTs (2T@SWCNTs) are derived from minimum energy calculations using a Lennard‐Jones expression to describe the van der Waals intermolecular interactions. The great number of atoms present the main handicap for the theoretical study of our systems. A hybrid approach is set out to build a dynamic model of 2T@SWCNTs systems. This approach combines density of functional theory and molecular dynamics. We have finally developed the process necessary to build the dynamic matrix of our systems. After calculation of the dynamical model, for the obtained configuration of 2T@SWCNTs, the nonresonant Raman spectra have been calculated using the spectral moment's method. The charges transfer in the hybrid systems has been investigated by analyzing the Raman active modes of 2T molecule and the G‐band modes of free SWCNTs and 2T@SWCNTs hybrid systems.
