The formation of SAPO-5 molecular sieves is studied under hydrothermal conditions in the presence a new templating agent, 1-benzyl-2,3-dimethylimidazolium hydroxide ([bzmIm]OH). syntheses were carried out by varying synthesis parameters, viz. crystallization temperature, heating time and reactants molar composition (SiO2, Al2O3, P2O5, [bzmIm]+, H2O) order to investigate role each parameter on S...

In situ synchrotron infrared microspectroscopy on single crystals of SAPO-34 reveals that a carbene insertion mechanism is responsible for the first carbon–carbon bond formation from surface methoxy groups.

Cu-SAPO-34 (Cu-CZC) and Fe-mordenite (Fe-MOR) their mechanical mixture (50 : 50) have been exhaustively investigated by means of operando X-ray absorption spectroscopy under NH3-SCR conditions.

Micro-/meso-/macroporous Cu-containing SAPO-34 prepared by the post-synthetic modification of a commercial support with diethylamine (DEA), shows enhanced activity in NH 3 -SCR-DeNO x .
