Catalytic routes for oxygenate conversion on solid acids and supported metal nanoparticles
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2024-12-01

Selective dehydration of polyols over solid acids and metal-acid bifunctional catalysts: Towards a catalytic toolbox for rational catalyst design
<p>Interest in biorenewable alternatives to existing petrochemicals has lead to increased interest in catalytic means of upgrading sugar-derived molecules into useful commodities. While some biorenewable chemicals aim to break into the existing market as a new product (polylactic acid, or PLA, is …

First-principles molecular modeling of structure-property relationships and reactivity in the zeolite chabazite
… that if we had a thorough understanding of how solid acids, especially zeolites, catalyze reactions, then we would be able to design heterogeneous catalysts to overcome these difficulties. The nature of the acid sites in zeolites and the factors contributing to enhanced catalytic activity have …

The low-temperature formation of mixed-metal oxides
… measurements show that the reaction between the solid reagents proceeds spontaneously, even at sub-ambient temperatures, and is driven by the liberation of water from the lattice of LiOH·H₂O. In this manner, Li₂MoO₄ is prepared as mono-disperse particles, which are smaller and more regularly …

Catalytic and adsorbent properties of solid acid catalysts studied by ammonia adsorption microcalorimetry
Solid acid catalysts are becoming of great importance within the chemical industry and their acidity is of great interest, as this determines their application, plus many of their catalytic properties can also be directly related with their acidity. There has been a drive towards heterogeneous …

A multi-technique approach to characterise acidic surface properties of microporous catalysts
… dimensions. Zeolites can act as very strong solid acids and function as heterogeneous catalysts in various industrial processes used to obtain polyethylene terephthalate (PET) or polyvinyl chloride (PVC). They are crucial for products with a significant market demand such as plastics used in …

An Examination of γ-valerolactone Ring Opening and Decarboxylation in Multiphase System and Over Various Solid Acid Catalysts
… to improve the yield to PEA catalyzed by mineral acids (H2SO4). A wide range of solvents was tested for their affinity towards GVL and PEA. And alkanes appeared to have the best resolution to separate PEA from GVL. A two-parameter Margules model was further applied to regress the activity …
