Co-Electrodeposited Pi-MnO2-rGO as an Efficient Electrode for the Selective Oxidation of Piperonyl Alcohol

“…44 In order to study the topography and roughness of the surface both bare and modified electrodes were subjected to optical profilometry studies. Figure 4 20 It is observed that there is no statistical difference in the roughness values on modification, thus it can be concluded that the roughness factor alone doesn't determine the electrocatalytic activity of the electrode, but it also depends on the chemical properties of the modifiers. Due to the unique electrochemical properties of rGO and Pi-MnO 2, their simultaneous deposition on CFP electrode has demonstrated better catalytic activity.…”

“…The slope was determined by plotting a graph of oxidation peak current (I p ) vs √scan rate (ν 1/2 ) and substituted in Randles-Sevcik equation to calculate ECSA (E a ). 20 i A CD n 2.69 10 1…”

“…15 Electrochemical oxidation of alcohols brought about by aminoxyls like TEMPO and 4-ACT have been extensively studied in recent years as they serve as convincing alternatives to traditional chemical synthesis. [16][17][18][19][20] Erstwhile, few electrochemical methods emerged for the synthesis of piperonal, 3,10,21 this is due to the fact that the application of electrochemistry in organic synthesis is an effective tool as it provides a platform for developing economical and ecofriendly methods for efficient atom economy. 22 However, the requirement of a large amount of electricity, expensive electrodes like Pt and glassy carbon (GC) electrodes, and the prolonged reaction time also pose problems.…”

“…The core level S 2p spectrum depicts the deconvoluted peaks at 169.23 eV and 167.84 eV, which indicates S 2+,4+ oxidation peaks present in the polymer layer. 36…”

Bioelectrocatalytic Synthesis: Concepts and Applications

“…Varghese et al introduced an electroenzymatic method for the synthesis of D-ribonolactone from protected Dribofuranose, an alternative to the classic Swern or Dess-Martin periodinane oxidations. [109] Laccase enzymes were immobilized on the carbon fiber paper (CFP) electrode to facilitate direct electron transfer. The enzymatic system catalyzes the oxidation of a mediator, TEMPO, which can then oxidize the substrate.…”
