Influence of Surface Modification on the Acid Site Distribution of HZSM-5
Abstract
Hydroxyl groups located on the external surface and in the pore mouth region of HZSM-5 zeolites with different crystal sizes were modified by chemical liquid deposition (CLD) of tetraethoxysilane (TEOS). The silylation of the acid sites was monitored using NH 3 sorption, IR spectroscopy of the zeolite hydroxyl groups, and adsorption of pyridine and di- tert -butyl-pyridine (DTBPy). Silylation reduced the concentration of Brønsted acid sites, preferentially in the pore mouth region of the zeolites, and led to a blocking of Lewis acid sites. The deactivation of Lewis acid sites was found to occur prior to the reaction with bridging hydroxyl groups and silanol groups. The efficiency of silylation achieved was found to depend on the particle size of the zeolite sample. A multicycle procedure can be used to increase the effects of the modification with TEOS.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
