Electrocatalytic reduction of trace nitrobenzene using a graphene-oxide@polymerized-manganese-porphyrin composite

Abstract

A more stable composite of graphene oxide encapsulated by the polymerized porphyrins realize the electrocatalytic reduction of nitrobenzene to nitrosobenzene.

CO-free, aqueous mediated, instant and selective reduction of nitrobenzeneviarobustly stable chalcogen stabilised iron carbonyl clusters (Fe3E2(CO)9, E = S, Se, Te)

“…The difference in catalytic efficiency may be due to the electron-donor properties of S/Se/Te. 37 In a further attempt to optimize the amount of hydrazine hydrate which was used as a hydrogen source in the reaction, a 0.5 mmol amount of hydrazine produced 19% yield of aniline, while increasing the amount of hydrazine signicantly increased the yield of aniline; however, no considerable [11][12][13][14][15][16]. Here, 2 mmol of hydrazine hydrate serves as the optimal amount to achieve the desired quantity of hydrogen for the reaction.…”

“…5 Nevertheless, due to the high catalytic potential of Fe(CO) 5 , it has been extensively used for various carbonylation reactions as well as as for high-nuclearity clustere formations. [6][7][8][9][10][11] Electron-transfer, 12 hydrogenation, 13 hydride transfer 14 and electrochemical methods 15 are some of the important available methodologies to furnish distinct amines by utilizing a nitro precursor. The reduction of nitrobenzene has gained tremendous interest due to its hazardous effect on the environment.…”

Voltamperometric Sensors and Biosensors Based on Carbon Nanomaterials Used for Detecting Caffeic Acid—A Review

“…Graphene is less expensive as compared to other carbon materials, it has very good electronic properties, high electrocatalytic activity, good mechanical strength, and high thermal conductivity [103]. Modified graphene-based electrodes have attracted enormous interest in recent years and they have been successfully used for the study of organic and biological molecules [104], glucose [105], hydrogen peroxide [106], dopamine [107], methanol [108] nitrite [109], melatonin [110], rutin [111], and nitrobenzene [112]. The graphene-based sensors used to detect CA will be presented in this paper.…”

Surface blocking of azolla modified copper electrode for trace determination of phthalic acid esters as the molecular barricades by differential pulse voltammetry: response surface modelling optimized biosensor

“…The DPV current decreased with increasing the concentration of nitrobenzene. 35 In another study, the nonylphenol molecularly imprinted polymers were grafted on the surface of acrylamide functionalized MWCNT modified glassy carbon electrode. This sensor was used for detection of nonylphenol.…”
