Special Issue Information

Dear Colleagues,

This new Special Issue, entitled “Research on Zeolites and Zeolite-Like Materials: Synthesis, Structure, Properties and Application”, is dedicated to zeolites and their use in the production of new materials, structures, and for use in appliances. Zeolites have played a major role in many fields in recent decades and have become a focus of interest for scientists and material engineers. A research intensification into zeolites has been recorded over the last fifty years; about 200 different structures have been synthesised or discovered and have found practical applications to a greater or lesser extent. In this Special Issue, we aim to review the latest developments in the science and engineering of zeolites, which are attracting increasing attention due to their potential technological applications. The main objective is to link performance and functionality to the fundamental properties, chemistry, and physics of these materials, as well as to the process characteristics, in order to provide a multidisciplinary perspective and deeper understanding of this topic.

This Special Issue aims to provide an interdisciplinary forum to discuss the latest research developments in the field of materials and structures and to provide a vision for future research.

We look forward to receiving your contributions.

A simple and low-cost synthesis assisted by seed crystals has been proposed to convert residual colorless glass powder into a Na-X zeolite. For this purpose, the optimal parameters for acid leaching of glass powder were studied to remove impurities that could interfere with the crystallization process. Then, the hydrothermal syntheses were supported by Na-X seed crystals (0% to 5%, wt.) to induce the growth of zeolite X, evaluating the crystallization time (12 h to 48 h) and the variation of the silicon source (acid-treated and untreated residues). The formation of the faujasite as the main phase, with a higher degree of structural order and microporosity, was observed with the previous treatment in the residue, a higher seed loading, and a shorter crystallization time. On the other hand, a phase competition between faujasite, gismondine, Linde type-A, and sodalite structures was observed in the zeolites synthesized from the untreated residue. In this case, the high seed loading and the longer synthesis time allowed the correct targeting of the faujasite structure with low structural order and micro/mesoporous properties. Furthermore, interzeolite transformations occur in all syntheses, where the framework type synthesized was influenced by the presence of a specific ion as a mineralizing agent. Full article

The dehydration of methanol to produce light olefins and gasoline, known as MTO (methanol-to-olefins) process requires acidic catalysts that maintain their acidity at reaction temperatures. Zeolites, such as SAPOs and ZSM-5, are commonly used for this purpose due to their acidic centers. The initial step in these experiments involves the activation or pretreatment of these solids to remove physically adsorbed water from their pores. Inadequate pretreatment can lead to the destruction of the existing Brönsted sites through the dihydroxylation of surface -OH groups. Therefore, it is crucial to pretreat the zeolites properly to preserve the Brönsted sites. One method is to subject the fresh catalyst to programmed dehydration, which involves desorption at a controlled temperature while monitoring the appearance of water that results from Brönsted site dihydroxylation. The temperature at which the dehydration peak appears determines the optimal reaction temperature. The results presented in this work will demonstrate the progressive deactivation of the catalysts when the reaction temperature exceeds 400 °C. Full article
