Development of Zeolite Catalyst Which has High Selectivity by Mechanochemical Treatment

Enhancement of CO2/CH4 Adsorptive Selectivity by Functionalized Nano Zeolite

In this work, we have modified a synthesized Y-type zeolite (Si/Al = 2.5), with three different amines to investigate of the influence of adsorbent’s surface modification on CO2 selectivity over CH4. The pristine and amine-functionalized NaY zeolites were characterized by X-ray diffraction (XRD), thermal gravimetric analysis (TGA), Fourier transform infrared (FT-IR), and N2 adsorption. The resu...

چشم توسط مایعات درون شکل گرفته و به درجاتی محافظت می گردد. گلوکوم عبارت از افزایش فشار درون کره چشم به بیش از حد طبیعی آن است که به دلیل وجود مشکلات در تخلیه مایعات درون آن ایجاد می گردد.

Morphology Induced Shape Selectivity in Zeolite Catalysis

Tuning selectivity of electrochemical reactions by atomically dispersed platinum catalyst.

Maximum atom efficiency as well as distinct chemoselectivity is expected for electrocatalysis on atomically dispersed (or single site) metal centres, but its realization remains challenging so far, because carbon, as the most widely used electrocatalyst support, cannot effectively stabilize them. Here we report that a sulfur-doped zeolite-templated carbon, simultaneously exhibiting large sulfur...

Understanding zeolite catalysis: inverse shape selectivity revised.

Anyone who has experience in moving house [the Angewandte team has just done this!] knows that those boxes filled with small books are the heaviest, because these small objects pack so easily. The same entropy effect explains the catalytic selectivity towards the formation of branched hydrocarbons in zeolites. The pink tubes represent the zeolite pores at high loading in which effective size di...
