Introduction
The research interests of my Group are the electrocatalytic carbon dioxide reduction reaction and physico-chemical investigations of organic electrosyntheses. We combine principles from chemical and reaction engineering with physical-electrochemical and instrumental-analytical methods. The focus is on the dynamic investigation of electrochemical micro- and macrokinetics, the degradation processes of electrocatalysts and the elucidation of reaction mechanisms in organic electrochemistry.

Article
The intramolecular dehydrogenative carbon-carbon bond formation of aromatic rings in the presence of catalytic amounts of an oxidising agent is herein described. The oxidative coupling is realised under indirect anodic conditions, utilising 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as an efficient redox mediator under acidic conditions. In co...

A polybenzopyrrole@nickel oxide (Pbp@NiO) nanocomposite was synthesized by an oxidative chemical one-pot method and tested as an active material for hybrid electrodes in an electrochemical supercapattery device. The as-prepared composite material exhibits a desirable 3D cross-linked nanostructured morphology and a synergistic effect between the pol...

The microkinetics of the electrocatalytic oxygen evolution reaction substantially determines the performance in proton-exchange membrane water electrolysis. State-of-the-art nanoparticulated rutile IrO2 electrocatalysts present an excellent trade-off between activity and stability due to the efficient formation of intermediate surface species. To r...

The performance of electrocatalytic water splitting in polymer electrolyte membrane electrolysis is substantially determined by the microkinetic processes of the oxygen evolution reaction (OER). Even highly active catalysts such as the nanoparticulated transition metal oxides IrO2, RuO2 and their mixtures, IrxRu1‐xO2, exhibit overpotentials up to s...
Article
Hydrogen (H2) produced from renewables will have a growing impact on the global energy dynamics towards sustainable and carbon‐neutral standards. The share of green H2 is still too low to meet the net‐zero target, while the demand for high‐quality hydrogen continues to rise. These factors amplify the need for economically viable H2 generation techn...

Eco-friendly inhibitors have attracted considerable interest due to the increasing environmental issues caused by the extensive use of hazardous corrosion inhibitors. In this paper, environmentally friendly PDG-g-PANI/Al2O3 composites were prepared by a low-cost inverse emulsion polymerization for corrosion inhibition of mild steel (MS) and stainle...
Presentation
Electrocatalytic water splitting is currently one of the most promising reactions to produce green hydrogen in a de-fossilized energy system. [1] The performance of PEM electrolyzers is substantially determined by the sluggish reaction kinetics of the oxygen evolution reaction (OER). Even highly active catalysts such as nanoparticulated transition...
Presentation
The role of proton exchange membrane water electrolysers (PEMWE) in providing clean and reliable green hydrogen is undeniable in a fully decarbonized energy system. Indeed, the ambitious “Hydrogen Shot” initiative by the U.S. DoE seeks to decrease in a decade green hydrogen pricing down to 1$/Kg H 2 .(1) Such endeavour will require a mass-scale imp...

Polybenzopyrrole (Pbp) is an emerging candidate for electrochemical energy conversion and storage. There is A need to develop synthesis strategies for this class of polymers that can help improve its overall properties and make it as suitable for energy storage applications as other well-studied polymers in this substance class, such as polyaniline...

The structure of IrO2 during the oxygen evolution reaction (OER) was studied by operando X-ray absorption spectroscopy (XAS) at the Ir L3-edge to gain insight into the processes that occur during the electrocatalytic reaction at the anode during water electrolysis. For this purpose, calcined and uncalcined IrO2 nanoparticles were tested in an opera...

The increasing scarcity of iridium (Ir) and its rutile-type oxide (IrO 2), the current state-of-the-art oxygen evolution reaction (OER) catalysts, is driving the transition toward the use of mixed Ir oxides with a highly active yet inexpensive metal (Ir x M 1−x O 2). Ruthenium (Ru) has been commonly employed due to its high OER activity although it...

The performance of high-rate supercapacitors requires fine morphological and electrical properties of the electrode. Polyaniline (PANI), as one of the most promising materials for energy storage, shows different behaviour on different substrates. The present study reports on the surface modification of fluorine doped tin oxide (FTO) with the sodium...
Article

Traces of species in batteries are known to impact battery performance. The effects of gas species, though often reported in the electrolyte and evolving during operation, have not been systematically studied and are therefore barely understood at present. This study reveals and compares the effects of different gases on the charge‐discharge charac...
Article
Electrocatalytic water splitting is currently one of the most promising reactions to produce “green” hydrogen in a decarbonized energy system. Its bottleneck reaction, the oxygen evolution reaction (OER), is catalysed by hydrous iridium, a stable and active catalyst material. Improving the OER requires a better and especially quantitative understan...

In the field of advanced energy storage, nanostructured Polyaniline (PANI) based materials hold a special place. Extensive studies have been done on the application of PANI in supercapacitors, however, the structure-property relationship of these materials is still not understood. This paper presents a detailed characterization of the novel sodium...

This review summarises the cobalt-catalysed reactions of the years 2008 through 2014. Covered are addition reactions, such as the hydrogenation of double bonds, the addition of C–H bonds to double and triple bonds, C–H activation reactions, cobalt-catalysed cross-coupling reactions and selected additions of H–B and H–Si bonds to unsaturated startin...

The [4+2] cross-benzannulation of conjugated enynes and diynes under cobalt-catalysis led to 1,2,3-trisubstituted benzene derivatives in good yields. The reaction proceeds smoothly in absolute regiospecific control when symmetrical diynes are applied. Moreover, the use of unsymmetrical diynes was investigated resulting in the formation of the unpre...

A highly reactive nickel catalyst comprising NiCl2(dppp) or NiCl2(dppe) with zinc powder, ZnI2 and Ph2PH, was applied in the isomerization of terminal alkenes to Z-2-alkenes. The double-bond geometry of the 2-alkene can be controlled via the reaction temperature to yield the 2-Z-alkenes in excellent yields and high Z-selectivities. The formation of...
