Abstract:A top-down desilication of Al-rich ZSM-5 zeolites and a bottom-up mesopores creating method were evaluated in this study. Three liquid-solid and one gas-solid heterogeneously-catalysed reactions were chosen to establish relationships between zeolites textural properties and their catalytic behavior in acid-catalysed model reactions that are influenced by shape selectivity: Diels-Alder cyclization between isoprene and methylacrylate, Methanol-to-Olefins (MTO) reaction, chlorination of iodobenzene with trichloroisocyanuric acid (TCCA), and Friedel-Crafts acylation of anisole by carboxylic acids with differing sizes. It is found amongst others that no optimal mesoporosity for all the different reactions can be easily obtained, but depending on the chosen application, a specific treatment has to be set to achieve high activity/selectivity and stability.

The exploitation of new materials for adsorptive separation of industrially important hydrocarbons is of great importance in both scientific research and petrochemical industry. Nonporous adaptive crystals (NACs) as a robust class of synthetic materials have drawn much attention during the past five years for their superior performance in adsorption and separation. Pillararenes are the main family of macrocyclic arenes used for NACs construction, where the structure–function relationship has been intensively studied. In the past two years, some emerging types of synthetic macrocyclic arenes have been successfully brought into this research field, showing the gradual enrichment and diversification of NACs materials. This Minireview summarizes the recent advances of synthetic macrocycle‐based NACs, which are categorized by various practical applications in molecular separation. Besides, NACs‐based vapochromic supramolecular systems are also discussed. Finally, future perspectives and challenges of NACs are given. We envisage that this Minireview will be a useful and timely reference for those who are interested in new molecular and supramolecular crystals for storage and separation applications.

“…Losch et al [ 99 ] and Wang et al [ 64 ] have instead proposed similar methods to modify carbon nanofibrers (CNFs) by covalent attachment of ILs. The synthesis procedure proposed by Losch et al consists of the introduction of carboxylic groups by oxidative treatment of the CNF, followed by a first reaction with SOCl 2 at 70 °C, a second reaction with 3‐chloro‐1‐propanol at 120 °C, and a third one with 1‐methyl‐imidazole at 95 °C.…”

Hydrogen fuel cells are a promising technology for the environmentally sustainable production of electricity. However, their commercialization is hindered by the sluggish kinetics of the oxygen reduction reaction and by the high cost of the state‐of‐the‐art platinum catalysts. To address these challenges, research has focused on the enhancement of the activity of platinum and platinum group metal (PGM)‐free electrocatalysts, by modifying their composition and topology. Recently, a new approach has emerged to boost the activity of ORR catalysts, based on engineering the electrochemical interface. Herein, the recent developments in the use of ionic liquids (ILs) to modify the triple‐point interface of ORR catalysts are summarized. In this review, the current understanding in the literature of the effect of IL layers is presented, along with the open questions and remaining challenges. A short perspective on the applicability of this simple and effective modification to other electrochemical reactions is discussed.
