DOI: 10.1016/j.micromeso.2018.07.005
Abstract: Abstract To improve the physicochemical properties of CHA-type zeolites, we synthesized a CHA-type titanosilicate zeolite (Ti-CHA) with titanium instead of aluminum incorporated into its framework. Ti-CHA zeolites with various Si/Ti ratios were directly prepared by… read more here.

DOI: 10.1039/d2cc04032h
Abstract: High-silica CHA-type aluminosilicates (Si/Al molar ratio >100) were synthesized hydrothermally in the absence of fluoride media, where the seed-assisted aging treatment played an important role on the crystallization. These aluminosilicates showed a long catalytic lifetime… read more here.

DOI: 10.3390/membranes11030229
Abstract: A high-silica chabazite (CHA) type zeolite membrane was prepared on the porous α-Al2O3 support tube by the secondary growth of seed particles. The dehydration performances of the membrane were determined using methanol, ethanol, 2-propanol, acetone,… read more here.
