Aromatics are major building blocks of polymers, or plastics, that turn up as everything from PET bottles for water to breathable, wrinkle-resistant polyester clothing. These petrochemicals comprise a specialized, value-added sector of the energy industry. The process for refining crude oil into use more
Researchers at the Paul Scherrer Institute PSI and from ETH Zurich want to make so-called zeolites more efficient. Today, these compounds are already indispensable additives in the chemical industry and have been used as catalysts in oil refineries since the 1960s. Now, in the journal Nature Materia more
Zeolites crystals, used among other things for refining petroleum to gasoline and biomass into biofuels, are the most-used catalysts by weight on the planet, and discovering mechanisms of how they form has been of intense interest to the chemical industry and related researchers, say chemist Scott A more
A new method to make zeolite nanosheets leads to high performance membranes for separation and purification processes. Credit: Prashant Kumar and Michael Tsapatsis, University of Minnesota more
The ancient Romans had a recipe for concrete that won't corrode in seawater. Scientists are trying to figure it out. more
Stains on clothes can be a pain to shift – luckily chemistry is on hand to help out! A range of different molecules are present in stain removers and detergents to help shift grease and dirt, and they can work in different ways. This graphic takes a look at how we can categorise different types of s more

Conversion of carbon dioxide (CO2) to more valuable chemicals has nowadays received the increasing attention from an environmental and industrial point of view. Herein, we computationally investigate the CO2 hydrogenation to formic acid on Lewis acidic zeolites by means of the density functional the more
MFI Zeolites exchanged with various cations have gained a great deal of attention as catalysts. Increase in the ion-exchange capacity of zeolites can improve their catalytic properties by introducing more active sites; however, the ion-exchange capacity of MFI zeolites is limited by maximum aluminum more
Photocatalysts based on TiO2 supported on two different synthetic zeolites (Faujasite CBV 760: SiO2/Al2O3 = 60 and Mordenite CBV 21A, SiO2/Al2O3 = 20), containing 10 wt % and 40 wt % TiO2 loading, have been synthesized using a sol-gel method without any further calcination. The structural, textural more
