Exploring Brønsted acids confined in the 10-ring channels of the zeolite ferrierite†
Abstract
Locations of Brønsted acids confined in the 10-ring channels of ferrierite have been unravelled by refining structural models of as-made and probe-molecule-adsorbed samples against powder X-ray diffraction data, respectively. By analysing both refinement results, it is suggested that Brønsted acid sites can be tailored by controlling the distribution of inorganic ions.
