Enhanced electrochemical dissolution of iridium oxide in acidic electrolytes through presence of metal ions
Raghunandan Sharma, Per Morgen, Darko Makovec, Sašo Gyergyek, Shuang Ma Andersen
Izvirni znanstveni članek
Oznake: elektrokatalizatorji;electrocatalysts;oxygen evolution reaction;acidic environment;
Nanoparticulate Ir-oxides are frequently used as highly active and robust anode electrocatalysts for acidic water electrolyzers. While their dissolution during the electrolyzer operation is unsought, it could be a green route for recovery of Ir from the spent electrodes. In this study, we explore su ...

Selection on antimony-doped tin oxide (ATO) as an efficient support for iridium-based oxygen evolution reaction (OER) catalyst in acidic media
Ikhlas Ahmad Khan, Per Morgen, Sašo Gyergyek, Raghunandan Sharma, Shuang Ma Andersen
Izvirni znanstveni članek
Oznake:
Reducing the iridium content while preserving high OER activity is an important prerequisite for the progress of inexpensive anodic water splitting electrocatalysts in low pH medium. Here we report the effects of bulk and surface structures of antimony doped tin oxide (ATO) supports on the ATO suppo ...

Microwaves assisted synthesis of IrRu alloy nanoparticles for acidic oxygen evolution reaction
Inayat Ali Khan, Per Morgen, Sašo Gyergyek, Raghunandan Sharma, Shuang Ma Andersen
Izvirni znanstveni članek
Oznake: elektrokatalizator;elektroliza vode;electrocatalyst;acidic oxygen evolution reaction;water electrolysis;durability;
Under the background of renewable hydrogen generation through proton exchange membrane water electrolysis, here we report highly efficient and stable iridium (Ir) and ruthenium (Ru) alloy based electrocatalysts for the acidic OER. The electrocatalysts were synthesized by a facile microwave-assisted ...

Oznake: iridijev oksid;stabilnost;iridium oxide;oxygen evolution reaction;carbon support;stability;
The development of efficient and durable oxygen evolution reaction (OER) electrocatalysts is critical for advancing proton exchange membrane water electrolyzers (PEMWEs). This study presents a nanostructured iridium oxide anchored on high-surface-area carbon (IrOx/C) OER electrocatalyst, synthesized ...
