AB  - Adjusting the morphological characteristics of a material can result in improved electrocatalytic capabilities of the material itself. An example of this is the introduction of rare-earth elements into the borate structure, which gives a new perspective on the possibilities of this type of material in the field of (bio)sensing. In this paper, we present the preparation of borates including La, Nd and Dy and their application for the modification of a glassy carbon electrode, which is used for the non-enzymatic detection of a biologically relevant molecule, vitamin B6 (pyridoxine). Compared with the others, dysprosium borate has the best electrocatalytic performance, showing the highest current and the lowest impedance, respectively, as determined using cyclic voltammetry and impedance tests. Quantitative testing of B6 was performed in DPV mode in a Britton–Robinson buffer solution with a pH of 6 and an oxidation potential of about +0.8 V. The calibration graph for the evaluation of B6 has a linear range from 1 to 100 μM, with a correlation coefficient of 0.9985 and a detection limit of 0.051 μM. The DyBO3-modified electrode can be used repeatedly, retaining more than 90% of the initial signal level after six cycles. The satisfactory selectivity offered a potential practical application of the chosen method for the monitoring of pyridoxine in artificially prepared biological fluids with acceptable recovery. In light of all the obtained results, this paper shows an important approach for the successful design of electrocatalysts with tuned architecture and opens new strategies for the development of materials for the needs of electrochemical (bio)sensing.

AB  - : Nanoparticles of TiO2 are suitable for many catalytic and photocatalytic applications due
to their extraordinary properties such as superhydrophobicity, semiconductivity, electron-rich, and
environmental compatibility. The main crystalline phases of TiO2
, anatase, and rutile possess different
crystal structures, crystallinity, crystalline sizes, and specific surface areas, and these characteristics
directly affect the catalytic performance of TiO2
. In the present study, domestic carbon material
enhanced with TiO2 nanoparticles was synthesized and used for the construction of a modified
carbon paste electrode. The electrocatalytic activity of the modified electrodes was investigated
depending on the TiO2 crystalline phases in the electrode material. Furthermore, the obtained
working electrode was utilized for triclosan detection. Under optimized experimental conditions, the
developed electrode showed a submicromolar triclosan detection limit of 0.07 µM and a wide linear
range of 0.1 to 15 µM. The relative standard deviations for repeatability and reproducibility were
lower than 4.1%, and with satisfactory selectivity, the proposed system was successfully applied to
triclosan monitoring in groundwater. All these results confirm that the sustainable production of new
and domestically prepared materials is of great benefit in the field of electrocatalysis and that the
morphology of such produced materials is strongly related to their catalytic properties.
