Modified reverse ADOR assembles Al-rich UTL zeolite from IPC-1P layers

Abstract

Extra-large pore zeolites clear the way for the synthesis of fine chemicals and bulky compounds unable to enter the channels of medium- and large-pore zeolites. However, such extra-large pore zeolites...

Double Four Ring Units‐Containing Zeolites: Synthesis, Structural Modification and Catalytic Applications

“…The recent report indicates the reconstructed Alcontaining UTL (Re-UTL(Al)) prepared by the modified Reverse ADOR process exhibits higher mesoporosity than directly synthesized Al-UTL, and the synthesis time of Re-UTL(Al) is obviously shortened to 14 days compared with 28 days of Al-UTL. [101] Besides, post-synthetic strategies allow the incorpora-tion of such heteroatoms into zeolite catalysts that cannot be obtained by direct synthesis. [17d,102] In terms of the epoxidation of alkenes and cycloalkenes, titanosilicate zeolites, such as Ti-MWW, [9b,103] Ti-MFI, [104] Ti-Beta, [105] and Ti-MOR, [106] are an excellent class of catalysts.…”

“…Another advantage is that the post‐synthesis method is relatively easy to flexibly regulate the properties of final catalysts, such as Al content, synthesis time, and porosity. The recent report indicates the reconstructed Al‐containing UTL (Re‐UTL(Al)) prepared by the modified Reverse ADOR process exhibits higher mesoporosity than directly synthesized Al‐UTL, and the synthesis time of Re‐UTL(Al) is obviously shortened to 14 days compared with 28 days of Al‐UTL [101] . Besides, post‐synthetic strategies allow the incorporation of such heteroatoms into zeolite catalysts that cannot be obtained by direct synthesis [17d,102] …”
