The field of impact electrochemistry, namely, electrochemical processes occurring at nanoparticles during collisions with a substrate electrode, has recently been applied to the recovery of commercially important metals. In this study, the reduction and oxidation of solution Mn(II) were observed on carbon black particles during nanoimpacts, with the onset potentials of the reduction and oxidation processes in good agreement with solution voltammetry. The formation of Mn(0) and MnO 2 was confirmed via scanning electron microscopy/ energy-dispersive X-ray (SEM/EDX) analysis and X-ray photoelectron spectroscopy (XPS) analysis. Coverages of between 0.2 and 0.6 monolayer equivalents were obtained for the reductive deposition of Mn, whereas for the anodic deposition of MnO 2 , a more complex picture was found due to the oxidation pathway from Mn(II) to MnO 2 .

“…In recent years much work has been done to reduce the discharge of wastewater and improve the yield of benzaldehyde in electrochemical production processes [1,2,3,4,5]. Few reports have been shown about the production of phenylacetaldehyde by electrochemical synthesis with less pollution.…”

Wastewater minimization in phenylacetaldehyde production by using indirect electrochemical oxidation of phenylethane instead of the seriously polluting traditional chemical process is described in this paper. Results show that high current efficiency of Mn(III) and high yield of phenylacetaldehyde can be obtained at the same sulfuric acid concentration (60%). The electrolytic mediator can be recycled and there will be no waste discharged.
