1-Butene metathesis over Mo/mordenite-alumina catalyst: Effect of sodium exchange degree in mordenite zeolite

open access: yes, 2013
A series of Mo/mordenite-alumina catalysts with progressive sodium exchange degrees in mordenite were prepared and their performance in 1-butene metathesis reaction was evaluated. Significant variations in product distribution and catalytic activity were

Catalytic Confinement Engineering for CO2 Conversion: From Catalytic Microenvironments to Sustainable Aviation Fuels

open access: yesCarbon Neutralization, Volume 5, Issue 4, July 2026.
Confinement engineering offers a unified strategy for CO2 conversion by regulating local reaction microenvironments around catalytic active sites. This review compares electrochemical CO2 reduction and thermocatalytic CO2 hydrogenation, highlighting how spatial confinement, interfacial electronic regulation, and promoter effects stabilize key ...

Triiodide Faujasites With Reactive, Ionic, Antimicrobial, and Catalytic Applications

open access: yesSmall Structures, Volume 7, Issue 7, July 2026.
Alkyl iodides and zeolites react under open‐air reaction conditions to give triiodide anions (I3−) inside the zeolite (I3−@zeolite), without any additive or solvent. The multigram solid, with up to ≈25 wt% I3− loadings, is active as a water disinfection agent, bacteria and yeast antiseptic, solid electrolyte, and catalytic solid for the carbonyl–olefin

THE ION-EXCHANGE PROPERTIES OF NATURAL ZEOLITE MORDENITE

open access: yesТонкие химические технологии, 2016
The cation exchange properties of mordenite (a Nakhchivan natural zeolite) were studied. Ion exchange of the original cations - sodium, potassium and calcium - by magnesium, strontium, cadmium, zinc and nickel cations was carried out.

Spectroscopy and Redox Chemistry of Copper in Mordenite

open access: yesChemPhysChem, 2014
AbstractCopper‐containing zeolites, such as mordenite (MOR), have recently gained increased attention as a consequence of their catalytic potential. While the preferred copper loadings in these catalytic studies are generally high, the literature lacks appropriate spectroscopic and structural information on such Cu‐rich zeolite samples.

Proton‐Exchanged Montmorillonite With Interlayer Accessibility as a Solid Acid Catalyst for the Upcycling of Polyoxymethylene

open access: yesChemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
The first microwave‐assistance‐free heterogeneous catalytic upcycling of polyoxymethylene (POM) into valuable cyclic acetals is achieved with a reusable proton‐exchanged montmorillonite (H‐Mont) catalyst. Combining interlayer accessibility with strong acidity, H‐Mont enables efficient, regenerable, and versatile transformations with potentially biomass‐

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3215-3227, June 2026.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

The Occurrence and Morphology of Naturally Occurring Respirable Mordenite Mineral Fibres in New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Mordenite is a naturally occurring zeolite mineral that is the seventh most common zeolite mineral globally, forming at low temperatures (≥100°C) in hydrothermal systems. In New Zealand, extensive deposits of mordenite are commonly associated with areas of hydrothermal alteration, particularly in the Coromandel and Taupo Volcanic Zones.

Alteration of Feldspar‐Rich Rocks on Ancient Mars and Its Possible Link to Ca/Fe‐Rich Carbonates

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Feldspar‐rich rocks have increasingly been discovered on the martian surface. They may have been an important part of the ancient martian crust and may be related to Ca/Fe‐rich carbonates (one of two types of carbonates on Mars and the other being Mg‐rich carbonates), but compared to mafic rocks, their interaction with water on ancient Mars is
