Special Issue Information
Dear Colleagues,
Zeolites have been utilized in industrial catalysis and separation processes for decades, initially in petroleum refinement and more recently in sustainable chemical applications. Their catalytic efficiency is attributed to three key properties: acidity, shape selectivity, and high surface area. Advances in post-synthesis modifications, such as dealumination, metal loading, and ion exchange, enable the tuning of acidity and porosity, thus optimizing the selectivity and stability of catalysts. Common zeolites such as Y, ZSM-5, mordenite, and β dominate catalytic cracking, alkylation, isomerization, and biomass conversion. Hierarchical zeolites, characterized by mesoporous structures, are particularly effective for reactions with bulky molecules during biomass conversion, pyrolysis, and the pre-cracking of hydrocarbons. Reducing the size of particles and introducing mesopores facilitate the diffusion of reactants to active sites. The modification of the zeolites via the incorporation of heteroatoms other than Si and Al in the silicate framework forms new Brønsted or Lewis acid sites. In certain applications, the hydrophobicity of the pore walls influences the concentration of organic reactants within the pores and the ability of water to bind to the surface. This property is crucial for the dehydration reactions commonly encountered in the valorization of biomass.
This Special Issue aims to highlight recent advances in the synthesis, characterization, and application of zeolite catalysts, emphasizing their role in sustainable and environmentally friendly industrial processes. We therefore welcome the submission of articles that provide insights into zeolite design and novel applications in renewable energy, pollution mitigation, and chemical transformations.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
