Heterogeneous Catalysis. In their Communication (e202207777), Patrick Hemberger et al. employed PEPICO spectroscopy to identify ketene and methylketene intermediates in methyl acetate conversion over the HZSM-5 zeolite.

In this work, porous nanoparticles of ferrite cobalt were prepared by dissolving CoCl2.6H2O and FeCl3 in ethylene glycol in a hydrothermal process. Using ethylene glycol instead of DI water as a solvent would cause to provide porous structure of ferrite cobalt. 0.05 ml of colloidal fluid of fabricated nanostructure was injected on interdigitated electrodes (IDE) on a printed circuit board (PCB)...

Designing sustainable processes is gaining momentum in the chemical engineering community. Conventional life cycle assessment approaches often employed to assess sustainability level of can be used compare alternatives. However, because they lack clear quantitative thresholds above which a process should deemed unsustainable, insight provided into whether technology truly absolute terms limited...

Sorption enhanced synthesis has been previously shown to improve carbon dioxide hydrogenation methanol by mitigating the thermodynamic limitations. This work investigates efficiency of via sorption focusing on determining optimal process parameters. The study is based upon a fully dynamic experimentally validated model which extended account for adsorbent regeneration, downstream product separa...

Heterogene Katalyse. In ihrer Zuschrift (e202207777) nutzen Patrick Hemberger et al. PEPICO-Spektroskopie zur Identifizierung von Keten- und Methylketen-Intermediaten in der Methylacetat-Umwandlung über HZSM-5-Zeolith.

A mass spectrometric method has been delineated for the identification of the epoxide functionalities in unknown monofunctional analytes. This method utilizes gas-phase ion/molecule reactions of protonated analytes with neutral trimethyl borate (TMB) followed by collision-activated dissociation (CAD) in an ion trapping mass spectrometer (tested for a Fourier-transform ion cyclotron resonance an...
