Alkaline manganese electrochemistry studied by in situ and operando spectropscopic methods - metal dissolution, oxide formation and oxygen evolution
Rabe, Martin; Toparli, Cigdem; Chen, Ying-Hsuan; Kasian, Olga; Mayrhofer, Karl J.J.; Erbe, Andreas (Journal article; Peer reviewed, 2019)Manganese-based systems are considered as candidate electrocatalysts for the electrochemical oxygen evolution reaction (OER), because of their abundance in biochemical oxygen producing catalyst systems. In this work, the ... -
Cyclodextrin inhibits zinc corrosion by destabilizing point defect formation in the oxide layer
Altin, Abdulrahman; Krzywiecki, Maciej; Sarfraz, Adnan; Toparli, Cigdem; Laska, Claudius; Kerger, Philipp; Zeradjanin, Aleksandar; Mayrhofer, Karl J.J.; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2018)Corrosion inhibitors are added in low concentrations to corrosive solutions for reducing the corrosion rate of a metallic material. Their mechanism of action is typically the blocking of free metal surface by adsorption, ... -
