Fundamental research campaigns in electrocatalysis often involve the use of model systems, such as single crystals or magnetron-sputtered thin films (single metals metal alloys). The downsides these approaches are that oftentimes only a limited number compositions picked and tested (guided by chemical intuition) validity trends is not verified under operating conditions typically present real devices. These together can lead to deficient conclusions, hampering direct application newly...
Abstract In recent years, gas diffusion electrode (GDE) half-cell setups have attracted increasing attention, bridging the gap between fundamental and applied fuel cell research. They allow quick reliable evaluation of catalyst layers provide a unique possibility to screen different electrocatalysts at close real experimental conditions. However, benchmarking electrocatalysts’ intrinsic activity stability is impossible without knowing their electrochemical active surface area (ECSA). this...
Liquid fuels are considered a promising alternative to hydrogen in proton exchange membrane fuel cells. In particular, isopropanol, which can be selectively oxidised acetone and further hydrogenated back isopropanol using electrochemical heterogeneous catalysis routes, respectively, opens the possibility of zero-emission cell operation without complex management molecular H2. However, maximum electric power such cells is still relatively low, attributed poisoning state-of-the-art Pt-Ru...
Abstract The selective electrochemical oxidation of 2‐propanol to acetone can be used in fuel cells deliver low‐carbon electricity and efficiently utilize hydrogen that is stored liquid organic carrier molecules. Here we study the electrooxidation alkaline electrolyte, on various commercially available carbon‐supported mono‐ bi‐metallic noble metal nanoparticles. We use voltammetry compare activity different catalysts, combine a flow cell with real‐time analytics monitor products reaction...
Abstract Ruthenium (Ru) or Ru‐based catalysts are widely used in various electrochemical applications such as biosensors, ammonia synthesis, CO 2 reduction, electrolyzers, fuel cells, operating at different conditions. While the activity of these is studied, works addressing stability less common, especially neutral alkaline environments. Therefore, we evaluate a real‐time potential‐dependent dissolution polycrystalline Ru via scanning flow cell coupled to inductively plasma mass...
Over the last decade, in situ or online inductively coupled plasma mass spectrometry (ICP-MS) has been established as a powerful tool for time- and potential-resolved assessment of electrocatalyst dissolution stability. On other hand, much more accessible practical realization ex ICP-MS studies three-electrode cells are not commonly carried out. Still, they can offer valuable insights into catalyst degradation during prolonged accelerated stress tests, thus complementing measurements. This...
