Ordered mesoporous (organo)silicas provide a highly tunable platform to modulate the hydrophobicity of their surfaces, through thermal control of surface hydroxyl density as well as the incorporation of organic framework linkers.

Multi-physical transport processes on multiple scales are occurring in electrochemical devices and components for CO2 electroreduction. These coupled transport processes determine the local environment in the catalyst layer and subsequently also the reaction rates at the catalytic sites.

Electrochemistry is a successful series of conferences, held every other year. The conference is jointly organized by GDCh Division Elektrochemie, GDCh Arbeitskreis Elektrochemische Analysenmethoden, DBG, DECHEMA, AGEF, GfKORR and DGO. Outstanding electrochemists from Germany and from abroad will highlight research results and current trends.

Cobalt oxides are among the best earth abundant catalysts for the oxygen evolution reaction (OER) in alkaline and neutral electrolytes. We have undertaken operando studies of two dimensional epitaxial cobalt oxide films [1-2] to gain insights into some questions that remain in debate.

Transition metal-nitrogen-carbon materials (M-N-C catalysts) are promising electrocatalysts in electrochemical applications. High temperature treatment in inert environment (pyrolysis) is the most common method for the synthesis of M-N-C catalysts and critical to achieve high electrocatalyst activity and electronic conductivity.

Platinum Group Metal-free (PGM-free) catalysts have been extensively developed for both Proton Exchange Membrane (PEM) and Alkaline Exchange Membrane (AEM) fuel cells aiming automotive, stationary and portable applications. In this lecture we will address the critical challenges that our team has faced on the way to practical application of such catalysts.

Fluxionality, or the presence of and interconversion between multiple possible energetic configurations, is vital for understanding a catalyst as it operates under actual reaction conditions.

Commercialized membrane electrolyzers use acidic proton exchange membranes (PEMs). These systems offer high performance but require the use of expensive precious-metal catalysts such as IrO2 and Pt that are nominally stable under the locally acidic conditions of the ionomer.
