Evaluation of performance characteristics of nano TiO2and TiO2-ZnO composite for DSSC applications and electrochemical determination of potassium ferrocyanide using cyclic voltammetry

“…However, the voltammetric response is improved at the modified carbon paste electrode, reflected by the enlargement of the peak currents and the decline of the potential difference. An increase in peak current was identified at the TiO 2 -ZnO modified electrode, providing greater surface area, resulting in increased electrode contacting area of potassium ferrocyanide, thus facilitating its electrochemical detection [32][33][34][35][36][37][38][39][40]. Since the electrode modified with TiO 2 -ZnO has exhibited better electrocatalytic property, it can be concluded that electron transfer via TiO 2 -ZnO composite to the transparent conducting film is effective and the mobility of electrons could be increased by optimizing the properties of photoanode semiconductor material, that is, utilizing different molar concentrations of TiO 2 and ZnO for the synthesis of composite, enhancing the surface area of the composite, which may lead to improved efficiency [41].…”

A novel, extreme low-cost poly (Erythrosine) modified pencil graphite electrode for determination of Adrenaline

“…ADR content in blood is linked to a slew of physiological activities 11 . Aberrant ADR levels are linked to a various disease, including Alzheimer’s disease, Sclerosis, hypoglycemia, stress, thyroid hormone disorders, and Parkin’s disease 12 – 14 . It stiffens blood vessels, raising heart rate, dilates lungs, and is known to activate the sympathetic nervous system’s flight or fight mechanism 15 , 16 .…”

Analytical Performance of Clay Paste Electrode and Graphene Paste Electrode-Comparative Study

“…Paste electrodes have received much attention due to their advantages, such as easily renewable surfaces, inexpensiveness, biocompatibility, and relatively wide potential windows [ 1 , 2 , 3 , 4 , 5 ]. Moreover, the incorporation of modifiers into carbon paste material makes it even more attractive in electroanalytical applications [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. The performance of chemically modified carbon paste electrodes depends on the properties of the modifier, which affect the selectivity of the electrodes, kinetics of an electrochemical reaction, and sometimes even the electrode reaction product [ 13 , 14 ].…”
