Οι καταλυτικές ιδιότητες του ζεόλιθου

Διεθνές Συμπόσιο για τους ζεόλιθους και τα μικροπορώδη Κρύσταλλα 2015 – Οι πρόσφατες εξελίξεις στην έρευνα για το ζεόλιθο (International Symposium on Zeolites and Microporous Crystals 2015 – Recent advancements in zeolite research)

Article Synopsis The International Symposium on Zeolite and Microporous Crystals 2015 (ZMPC2015) was held at the Sapporo Convention Center, Japan, from 28th June to 2nd July 2015 and had 435 attendees from 32 countries, with 75% from Japan, China, Korea or Taiwan. 396 presentations covered all aspects of zeolites and microporous crystals over four days. Catalysis and synthesis were the two main themes (46% of all presentations) with the others being: new porous materials; membranes and films; adsorption and diffusion; characterisation; novel applications; industrial applications; layered materials; computational chemistry; post-synthetic treatment; crystallography; and ion exchange. There were six plenary talks ... Διαβάστε περισσότερα

Μια γενική μέθοδος για την ενσωμάτωση Αλουμινίου σε Ζεόλιθους υψηλής περιεκτικότητας σε πυρίτιο με χρήση Φθοριούχου μέσου (General Method for Aluminum Incorporation into High-silica Zeolites Prepared in Fluoride Media)

Takahiko Moteki and Raul F. Lobo Chem. Mater., Just Accepted Manuscript DOI: 10.1021/acs.chemmater.5b04439 Publication Date (Web): December 17, 2015 Copyright © 2015 American Chemical Society Abstract The fluoride method of zeolite synthesis yields materials with unique characteristics such as high Si/Al ratio, large crystal size, and hydrophobic properties, and it has been advantageous for the synthesis of new pure-silica or high-silica zeolites. It is often difficult, however, to incorporate aluminum—and thus bring about useful catalytic properties—in materials prepared through the fluorite method. In this report we show that FAU-type zeolites are an effective source of aluminum to the growing crystals ... Διαβάστε περισσότερα
