Identification of the surface species in electrochemical promotion: Ethylene oxidation over a Pt/YSZ catalyst

Toghan, Arafat; Greiner, Mark; Knop-Gericke, Axel; Imbihl, Ronald (Cambridge : RSC Publ., 2021)

The electrochemical promotion of the C2H4 + O2 total oxidation reaction over a Pt catalyst, interfaced to yttrium stabilized zirconia (YSZ), has been studied at 0.25 mbar and T = 650 K using near ambient pressure X-ray ...
Is iridium demand a potential bottleneck in the realization of large-scale PEM water electrolysis?

Minke, Christine; Suermann, Michel; Bensmann, Boris; Hanke-Rauschenbach, Richard (New York, NY [u.a.] : Elsevier, 2021)

Proton exchange membrane water electrolysis (PEMWE) is a key technology for future sustainable energy systems. Proton exchange membrane (PEM) electrolysis cells use iridium, one of the scarcest elements on earth, as catalyst ...
Multiple polymerization-formation of hybrid materials consisting of two or more polymers from one monomer

Ebert, T.; Wollbrink, A.; Seifert, A.; John, R.; Spange, S. (Cambridge : Royal Society of Chemistry, 2016)

Hybrid materials consisting of three different components were synthesized by the polymerization of one heterotrifunctional monomer in just one reaction step using, at the most, one catalyst. The polymerization of ...
Optimization of anodic porous transport electrodes for proton exchange membrane water electrolyzers

Bühler, Melanie; Hegge, Friedemann; Holzapfel, Peter; Bierling, Markus; Suermann, Míchel.; Vierrath, Severin; Thiele, Simon (Cambridge : Royal Society of Chemistry, 2019)

In this study we investigate the potential of porous transport electrode (PTE) based membrane electrode assemblies (MEAs) for proton exchange membrane water electrolysis. The focus is on the overpotential determining anodic ...
Präparative organische Chemie unter Verwendung einfach herzustellender Katalysatoren

Bölsing, Friedrich; Hakim, Assadollah (Berlin : De Gruyter, 1978)

There are numerous simple chemical reactions in which reaction products arise, which compared with the materials at the outset, possess a considerably greater surface area. A significant example is the reaction of aluminium ...
