Long-lived catalytic converter reduces diesel emissions

Diesel vehicles today emit fewer pollutants than older vehicles, thanks to a zeolite catalytic converter that was invented around 10 years ago. Although many groups have investigated this catalyst since then, it was still ...

Zeolite catalysts pave the road to decentral chemical processes

Fuel from waste? It is possible. But hitherto, converting organic waste to fuel has not been economically viable. Excessively high temperatures and too much energy are required. Using a novel catalyst concept, researchers ...

Scientists change properties of zeolites to improve hemodialysis

Scientists of Tomsk State University are working on changing physicochemical properties of zeolites using thermal and mechanical treatment. Based on the results of this research, scientists will be able to create a new material ...

How to heal broken bonds, catalyst style

While popular catalysts called zeolites could help turn paper manufacturing waste and other biomass into fuel, the catalyst crumbles after just two days in hot water. And that's a problem because hot water is nearly ubiquitous ...

Hydroxyl radicals speed up zeolite formation

(Phys.org)—Zeolite is a Greek word that literally means a boiling stone. They are porous materials used as adsorbents, catalysts, and as ion-exchangers, and used for water filtration, detergents, and air separation, among ...

Aluminum clusters shut down molecular fuel factory

Despite decades of industrial use, the exact chemical transformations occurring within zeolites, a common material used in the conversion of oil to gasoline, remain poorly understood. Now scientists have found a way to locate—with ...
