Let’s go Salen into the future! #Electrosnythesis, that is, converting substrates to useful products with the help of electricity, benefits from the introduction of #electrocatalysts that mediate between the electrode and the species in solution. Metal #salens, modular in their design and thus easily tunable, have been found useful to avoid high overpotentials and to increase the turnover numbers. Yet, using them as solution species makes downstream separation more complicated, costly, and time consuming. Zach N. and Shelley Minteer (University of Utah) highlight key advancements in the immobilization of metal salens for tackling this issue. Using different electrode immobilization techniques, such as polymerization and covalent attachment, straightforward separation and recycling of catalysts is made possible. With key examples ranging from water oxidation over CO2 reduction to organic electrosynthesis, this Review aims to help finding other applications, stimulate research into flow reactors and syntheses at scale.

?? ?? New materials research from our electrolysis group on ???????????????? ?????????????????????? as a catalyst. In PEM water electrolysis cells, ???????? ?????????? ????????????, such as platinum and iridium, are used as ?????????????????? for efficient energy conversion. To reduce the costs of green hydrogen produced via electrolysis, R&D efforts aim to minimize the use of rare metal catalysts, while maintaining performance requirements. Our colleague Lukas Stein, together with Hadir Borg from the Institute of Physical Chemistry and Electrochemistry, and an extended team of researchers at the Leibniz University of Hannover, have created a novel, highly porous platinum cryoaerogel as a catalyst. It achieved a ?????? ???????????????? ?????????????? (0.15 mg cm-2), while ?????????????????? its ?????????????????????? in a 500 h durability test. The experimental characterization of the material and electrolysis cell measurements are presented in the Applied Energy Materials Journal: https://lnkd.in/dK6vVPEn ? Key findings include: ??Morphology, structure and electrochemical performance of the cryoaerogel highly depend on the pyrolysis step temperature, the resulting porosity and surface coverage ??At a pyrolysis temperature of 300 °C, stable short-term performance with a platinum loading of only 0.15 mg cm-2 is achieved ??Over a long-term test period of 500 h, no apparent degradation can be observed and the electrical contact is improved ? #Cryoaerogel #HER #PEMWE #Platinum #Hydrogen #CathodeCatalyst #materialsresearch #catalysis #electrolysis #PEMelectrolysis #greenhydrogen Thanks to all co-authors: Christoph Wesemann, Zhijun Zhao, Christopher Mo?, Patrick Trinke, Mohammed Ismael, Boris Bensmann, Nadja Bigall, Dirk Dorfs, Richard Hanke-Rauschenbach

?? Science to Read by Technical Electrocatalysis Laboratory ? ?? How are the reduction kinetics of CuxO foams influenced by the precursor structure (amorphous vs. crystalline) and presence of Cu+ and Cu2+ species during #CO2RR? ?? What effect does the electrochemical protocol have on the oxide-metal transition? Together with colleagues from Universit?t Bern and Carl von Ossietzky Universit?t Oldenburg published in #JournalofMaterialsChemistryA Royal Society of Chemistry, we addressed these questions and highlight that the oxide-metal transition kinetics are strongly dependent on the initial abundance of Cu2+ species and precursor structure (ordered vs. amorphous). Our work reveals that the different chronoamperometric experiments strongly influence the electrochemical stability of Cu+ species within the CuxO foams during CO2 electrolysis.

Dear All, Pleased to share our recent work on Cu single atom catalysts (Cu-C3N4) for the oxidative dehydrogenation of N-heterocycles published in Journal of Colloid and Interface Science, 2024. The as-synthesized and well-characterized Cu@mpg-C3N4 single-atom photocatalyst is then evaluated for its efficacy in converting N-heterocycles into corresponding N-heteroaromatic compounds with excellent conversion and selectivity (>99 %). This transformation is achieved using water as a green solvent and a 30 W white light as a visible light source, demonstrating the catalyst's potential for sustainable and environmentally benign reactions. Here is complete access of this paper. https://lnkd.in/dWwsDiVu Heartiest Congratulations to all authors. Well done?Rahul Gaikwad, PhD. Dinesh Chaudhari INDRAJEET R. WARKAD, PhD Shan Jiang Jeffrey T.

I’m thrilled to share our latest contribution to the field of heterogeneous catalysis. Our study, titled “Insight into the Interaction of Perovskite-Like Surfaces (LaMnO? and LaCoO?) with Ar, H?, CO, and O? through NAPXPS Analysis,” delves into the surface properties of these remarkable materials. They hold immense potential as catalytic systems in diverse reactions critical for the energetic transition. https://lnkd.in/es-kfFhg
