a microbial fuel cell using Permanganate as the cathodic electron acceptor
Journal of Power Sources, 2006Co-Authors: Q Zhao, Jinna Zhang, Junqiu Jiang, S. ZhaoAbstract:Abstract The microbial fuel cell (MFC) was proved to be a novel bioprocess capable of recovering electrical energy from organic matter. In this study, we report that by using Permanganate as the cathodic electron acceptor for a MFC we were actually able to recover much more electrical power than using other existing types of electron acceptors, e.g. using Permanganate as the cathodic electron acceptor for a two-chamber MFC generated a maximum power density of 115.60 mW m −2 which was, respectively, 4.5- and 11.3-fold higher than that produced by using hexacynoferrate (25.62 mW m −2 ) and oxygen (10.2 mW m −2 ) as the cathodic electron acceptor. This could be attributed to the higher open circuit potential (OCP) provided by Permanganate in the MFC. Besides, pH, unlike Permanganate concentration, was further found to have a major impact on the OCP and the cathode potential. SEM and XPS analysis demonstrated that manganese dioxide (MnO 2 ) was in fact the main reduced product of the Permanganate at pH 3.6. Moreover, as compared to a two-chamber MFC, a bushing MFC using Permanganate as the cathodic electron acceptor achieved an unprecedented maximum power-output of 3986.72 mW m −2 . This study for the first time showed that Permanganate could be used as an effective cathodic electron acceptor for a MFC.

effect of Permanganate concentration on the formation and properties of phosphate Permanganate conversion coating on az31 magnesium alloy
Corrosion Science, 2013Co-Authors: Weijen LiAbstract:Abstract This study investigated the role of Permanganate in phosphate solutions in the formation and corrosion resistance of phosphate/Permanganate coatings on AZ31 magnesium alloys. Experimental results showed that Permanganate was reduced to manganese (IV) oxide together with the dissolution of magnesium during the conversion coating treatment. Adding more Permanganate to the phosphate solution resulted in a thinner coating with a compact magnesium oxide layer contacting the AZ31 plate. Moreover, the thinner coating had fewer cracks and displayed higher polarization resistance and corrosion resistance than the thicker counterpart formed in the solution with less Permanganate.

Permanganate conversion coating on az31 magnesium alloys with enhanced corrosion resistance
Corrosion Science, 2015Co-Authors: Shunyi JianAbstract:Abstract Necessity for developing alternatives to chromate conversion coatings has increased in the last decade. A chromate-free conversion coating treatment, mainly in Permanganate solution, was developed in this study for AZ31 magnesium alloys. The coating formed after 90 s of immersion consisted of a continuous nearly crack-free layer with an average thickness of 230 nm. The results of the electrochemical measurements and the salt spray tests demonstrated that the corrosion resistance of the AZ31 alloy was markedly improved by the Permanganate conversion treatment. Moreover, this thin Permanganate conversion coating had sufficient electrical conductivity, ensuring the magnetic shielding properties of the AZ31.
