We report herein the preparation, characterization, and catalytic performance of a series heterogeneous catalysts featuring highly dispersed zinc sites on zeolitic SSZ-13 ZSM-5 frameworks. The materials are evaluated in CO2-assisted oxidative ethane dehydrogenation, very important reaction for synthesis platform chemicals. In particular, we find that Zn2.92/SSZ-13 exhibits high reactivity conversion C2H6 CO2 ethene selectivity. line with experimental results, show selective character catalyst is due to characteristic compositional structure support its topology can effectively confine molecules. An in-depth molecular analysis via operando studies DFT calculations shows rate-limiting step second C–H bond dissociation give C2H4. addition reduces energy barrier this step, favoring desorption C2H4 while limiting byproduct formation. Overall, work demonstrates breakthrough potential made species zeolites relevant transformations.

The mitigation of decomposition reactions lithium-ion battery electrolyte solutions is critical importance in controlling device lifetime and performance. However, due to the complexity system, exacerbated by diverse set compositions, electrode materials, operating parameters, a clear understanding key chemical mechanisms remains elusive. In this work, operando pressure measurements, solution NMR, electrochemical methods were combined study oxidation reduction at multiple cell voltages. Two-compartment LiCoO2/Li cells cycled with conducting glass-ceramic separator so that species formed each could be identified separately further these opposite prevented.
