“…As shown in (Figure 7), Pt nanoparticles were deposited by electrochemical method on the polythiophene coated stainless steel substrate which resulted in the uniform dispersion of Pt on the PTh coated SS leading to the generation of nanoclusters, which ameliorated the electroactive surface area and was highly efficient in captivating benzyl alcohol onto the electrode surface. [53] The combination of various conducting polymers along with different metals has paved the way for numerous research. One such study reports that the permeable morphology of PANI is improving the specific surface area for Pd deposition on PANI/CFP electrodes.…”

Over the last few decades, the interest in green and sustainable chemistry has led to the development of different synthetic methodologies which utilize clean reagents. In that direction, the electro-oxidation reactions are considered as one of the most interesting and promising methods. This is predominantly due to their environmentally benign nature, as oxidation can be achieved without the need for commonly used oxidizing agents. 2,2,6,6-Tetramethylpiperidinyloxyl radical commonly known as TEMPO is a stable aminoxyl radical utilized for the oxidation of various classes of alcohols to carbonyl compounds by using cyclic voltammetry. The present review focuses on the various electrochemical reactions utilizing TEMPO as a mediator such as the oxidative conversion of alcohols, carbohydrates, amines, sulphur-containing compounds, and alkenes in both laboratory as well as industrial scales and covers literature from 1950 till present date. The properties, reactivity, and yield percentages of these reactions would provide a basis for better electrocatalyst design in future studies involving TEMPO and its derivatives as mediators.

Electrochemically deposited MnO 2 on graphene coated Pencil Graphite Electrode (PGE) has been used to develop a facile electrochemical sensor for the determination of Cholesterol. Cyclic voltammetric (CV) studies and electrochemical impedance spectroscopic (EIS) technique were used to investigate the electrochemical properties of the modified sensing platform. The physicochemical properties of the modified electrodes were characterized by X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The experimental conditions such as effect of scan rate, concentration and pH were optimized. The linear dynamic range for the determination of Cholesterol was found to be 12 × 10 À 10 M-240 × 10 À 10 M under optimum conditions. The ultralow level of detection limit (0.42 nM) demonstrates the high sensitivity of the proposed method. The developed method was successfully applied for the non-enzymatic determination of Cholesterol in human blood samples at ultralow levels.

“…At the same current density, the required potential is lower than the potential of platinum decorated polythiophene modified stainless steel electrodes (1.88 V vs RHE). 29 On the contrary, the corresponding value is 0.94 V vs Hg/HgO potential for the SS pristine membrane. The lower required potential implied that lower electric resistance can be achieved after Co 3 O 4 is immobilized in the pores of the SS pristine membrane.…”

An electrocatalytic membrane structured reactor with a stainless steel membrane as the Co3O4 catalyst carrier (Co3O4@SS EMSR) has been fabricated for benzyl alcohol oxidation coupled with hydrogen evolution. The structural characterization shows that the Co3O4 catalyst with the average size of 20 nm has been immobilized in the membrane pores. The electrochemical characterization indicates that the electrochemical active surface area can be increased and faster electron transfer can be achieved. During the process of benzyl alcohol oxidation coupled with hydrogen evolution by Co3O4@SS EMSR via flow-through mode, the benzyl alcohol conversion of 99% and the selectivity of benzoic acid of 97.7% with the Faraday efficiency of 95.9% for benzoic acid production can be achieved. The hydrogen production from the experiments is approximately consistent with the theoretically calculated hydrogen production, and a Faraday efficiency of 99% for hydrogen evolution can be achieved. The cell voltage during benzyl alcohol oxidation coupled with hydrogen evolution under the flow-through mode is reduced by 850 mV, and energy consumption is reduced by 2.03 kWh NmH2 –3 under the condition of a current density of 2.6 mA cm–2, compared with those of hydrogen production by water electrolysis with the oxygen evolution reaction.
