Manuscript Submission Deadline 12 December 2022
Manuscript Extension Submission Deadline 19 January 2023

Molecular sieves are porous crystalline or non-crystalline solids with ordered channels, which have been used in many industrial processes, such as adsorption separation and catalysis. They are classified into three types according to the IUPAC rule: microporous (<2 nm), mesoporous (2-50 nm), and macroporous (>50 nm) molecular sieves.

The microporous molecular sieves have excellent intrinsic catalytic activity and hydrothermal stability, but their diffusion property for large molecules is dismissed. On the contrary, mesoporous and macroporous molecular sieves have good diffusion properties, but the amorphous structure leads to poor hydrothermal stability. Therefore, much research focuses on the synthesis and application of hierarchical molecular sieves.

This Research Topic aims to highlight research covering all aspects of molecular sieves, ranging from their synthesis, characterization, modeling, as well as shaping and evaluation for practical applications. We welcome the submission of Original Research, Review, Mini Review, and Perspective articles on themes including, but not limited to:

• New strategies to synthesize hierarchical molecular sieves, including hydrothermal, solvolysis, solvent-free, post-synthesis, substitution, etc.
• Physico-chemical characterization of hierarchical molecular sieves, including spectroscopic, microscopic, etc.
• Theoretical chemistry and modeling of hierarchical molecular sieves.
• Applications of hierarchical molecular sieves in Catalysis: including fundamental research, pilot plant, and industrial application.

Keywords: hierarchical, Molecular Sieves, Catalysis, hydrothermal, solvolysis, post-synthesis, substitution, industrial application


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
