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, ... -
How to probe structure, kinetics and dynamics at complex interfaces in situ and operando by optical spectroscopy
Erbe, Andreas; Nayak, Simantini; Chen, Ying-Hsuan; Niu, Fang; Pander, Marc; Tecklenburg, Stefanie; Toparli, Cigdem (Chapter, 2017)Techniques using light in a large spectral range are well suited to study interfaces. Photon-based techniques have a special strength when it comes to application in situ and operando. This article introduces some of the ... -
In situ and operando observation of surface oxides during oxygen evolution reaction on copper
Toparli, Cigdem; Sarfraz, Adnan; Wieck, Andreas D.; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2017)Formation and dissolution of oxide on copper under transpassive conditions, i.e. during OER and transpassive dissolution, in alkaline electrolyte was investigated by a combination of electrochemical techniques and in situ ... -
State of the surface of antibacterial copper in phosphate buffered saline.
Toparli, Cigdem; Hieke, Stefan; Altin, Abdulrahman; Kasian, Olga; Scheu, Christina; Erbe, Andreas (Journal article; Peer reviewed, 2017)The state was investigated of the copper surface in phosphate buffered saline (PBS; 140 mM Cl−, 10 mM phosphate; pH 7) by a combination of cyclic voltammetry (CV) and chronoamperometry (CA) with in situ spectroscopic ... -
What is the trigger for the hydrogen evolution reaction? – towards electrocatalysis beyond the Sabatier principle
Zeradjanin, Aleksandar; Polymeros, George; Toparli, Cigdem; Ledendecker, Marc; Hodnik, Nejc; Erbe, Andreas; Rohwerder, Michael; La Mantia, Fabio (Peer reviewed; Journal article, 2020)The mechanism of the hydrogen evolution reaction, although intensively studied for more than a century, remains a fundamental scientific challenge. Many important questions are still open, making it elusive to establish ...
