Polycondensation as a Universal Method for Preparing High-density Single-atom Catalyst Libraries

Mounir Driss Mensi, Paul Joseph Dyson, Daniel Ortiz Trujillo, Pascal Miéville, Miyeon Chang, Xinbang Wu, Xunhui Wang, Laura Piveteau, Ariana Serban, Timo Markus Oskar Felder, David Fernando Reyes Vasquez

Single-atom catalysts (SACs) present a promising subclass of classic heterogeneous catalysts by maximizing metal dispersion and enhancing efficiency. Although high-density SACs (HD-SACs) are reported, their synthesis is typically constrained to specific me ...

Field-enhanced CO electroreduction in membrane electrolyzers at a dehydrated interface

Xile Hu, Miyeon Chang, Wenhao Ren, Nanjun Chen

Zero-gap membrane electrode assembly (MEA) CO electrolyzer stands as a promising technology for circular carbon economy. However, current CO electrolyzers are energetically inefficient when operating at ampere-level current densities. Here, by analyzing th ...

Synergistic interactions between PtRu catalyst and nitrogen-doped carbon support boost hydrogen oxidation

Andreas Schueler, Jeremy Luterbacher, Xile Hu, Anna Krammer, Weiyan Ni, Lichen Bai, Miyeon Chang, Seunghwa Lee, Songlan Sun, Seongmin Jin, Yiwei Zheng

Hydroxide exchange membrane fuel cell (HEMFC) is a potentially cost-effective energy conversion technology. However, current state-of-the-art HEMFCs require a high loading of platinum-group-metal (PGM) catalysts, especially for the hydrogen oxidation react ...

Mapping Catalyst‐Solvent Interplay in Competing Carboamination/Cyclopropanation Reactions

Anne-Clémence Corminboeuf, Matthew Wodrich, Nicolai Cramer, Miyeon Chang, Simone Gallarati

Group 9 metals, in particular Rh III complexes with cyclopentadienyl ligands, are competent C–H activation catalysts. Recently, a Cp*Rh III catalyzed reaction of alkenes with N -enoxyphthalimides showed divergent outcome based on the solvent, with carboami ...

One-Pot Synthesis of 1-[(Triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TIPS-EBX): Process Safety Assessment and Impact of Impurities on Product Stability

Jérôme Waser, Stefano Nicolai, Lionel Schouwey, Durga Prasada Rao Hari, Paola Caramenti, Miyeon Chang

The hypervalent iodine reagent 1-[(TriIsoPropylSilyl)Ethynyl]-1,2-BenziodoXol-3(1H)-one (TIPS-EBX) is among the most useful electrophilic and somophilic alkynylation reagents. Herein, we report a new synthetic protocol to access this reagent in one step fr ...
