DOI: 10.1016/j.jcat.2017.01.015

Abstract: Abstract La/SAPO-11 was synthesized via one-pot method. Lanthanum ions protect framework from distortion under the severe thermal (600 °C, 4 h) and hydrothermal (800 °C, 4 h) conditions. A higher retention of Bronsted acid sites (45.5%) is obtained after… read more here.

DOI: 10.1021/acs.inorgchem.4c01816

Abstract: SAPO-37 molecular sieve, characterized by its three-dimensional 12-membered-ring FAU structure, has drawn wide attention due to its unique properties and catalytic potential. However, its susceptibility to framework collapse under low-temperature and humid conditions hinders practical… read more here.
