“…Electrodes modified with cobalt oxide nanoparticles showed excellent electrocatalytic activity on glucose [15], arsenic(III) [16], nitrite [17], H 2 O 2 [18] , and p-nitrophenol [19]. Several preparation methods for cobalt oxide nanoparticles have been reported based on hydrothermal synthesis [20], precipitation [21], electrodeposition [22,23], as well as synthesis using leaf extracts [24]. Electrodeposition enables the formation of cobalt oxide nanoparticles in situ on an electrode in a fast and controlled manner [25].…”

Electrodeposition of Cobalt Oxides on Carbon Nanotubes for Sensitive Bromhexine Sensing

We develop an electrochemical sensor for the determination of bromhexine hydrochloride (BHC), a widely use mucolytic drug. The sensor is prepared by electrodeposition of cobalt oxides (CoOx) on a glassy carbon electrode modified with carboxylated single-walled carbon nanotubes (SWCNT). A synergistic effect between CoOx and SWCNT is observed, leading to a significant improvement in the BHC electrooxidation current. Based on cyclic voltammetry studies at varying scan rates, we conclude that the electrochemical oxidation of BHC is under mixed diffusion–adsorption control. The proposed sensor allows the amperometric determination of BHC in a linear range of 10–500 µM with a low applied voltage of 0.75 V. The designed sensor provides reproducible measurements, is not affected by common interfering substances, and shows excellent performance for the analysis of BHC in pharmaceutical preparations.

“…This method has a number of advantages, as opposed to other known methods of rhenium production; it allows obtaining rhenium in metallic and powder form; compact, plastic, non-porous and coherent rhenium layers may be formed on a complex large-scale substrate. Chloride [ 14 , 15 , 16 , 17 ], fluoride [ 18 , 19 ], chloride–fluoride [ 20 ] and fluoride–borate melts [ 2 , 21 , 22 ] may be used as electrolytes.…”

Rhenium Electrodeposition and Its Electrochemical Behavior in Molten KF-KBF4-B2O3-KReO4

The electrochemical behavior of rhenium ions in the molten KF-KBF4-B2O3 salt was systematically studied, and pure metallic rhenium was obtained at the cathode. The processes of rhenium ions reduction and diffusion in molten KF-KBF4-B2O3 were determined using cyclic voltammetry, stationary galvanostatic and polarization curves analyses. The values of diffusion coefficients were 3.15 × 10−5 cm2/s and 4.61 × 10−5 cm2/s for R1 and R2, respectively. Rhenium electrodeposition was carried out at a constant potential. The process of rhenium cathode reduction in KF-KBF4-B2O3 at 773 K was found to be a one-step reaction Re(VII) → Re, and rhenium electrodeposition presumably occurred from two types of complex rhenium ions (KReO4 and K3ReO5). Both processes are quasi-reversible and controlled by diffusion. The obtained cathode deposit was analyzed by SEM, EDX, ICP-OES and XRD methods. The obtained deposit had a thread structure and rhenium was the main component.
