A catalyst is a substance that can help the reactants in a chemical reaction react with each other faster. A catalyst does not actually become part of the products of the reaction. Summary. Students ...

Most of the catalysts used in bulk chemistry processes are heterogenous surface catalysts; heterogenous in that they are in a different physical state from the reactants, usually a solid catalyst ...

This chemical process employed three different bespoke heavy metal catalysts: one to add a carbon-carbon double bond to the polyethylene polymer and the other two to break the chain at this double ...

Brookhaven National Laboratory have designed a new way to convert abundant carbon dioxide (CO2) into formate (HCO2-), an ...

A high-performance catalyst that dissolves polyester and realizes chemical recycling Solving the plastic waste problem by synthesizing chemicals from vegetable oil ...

Researchers are studying chemical catalysts that can produce hydrogen gas from iron-rich rocks. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to ...

Plastic bottles and bags can be vaporised into chemical building blocks and turned into new plastics with all the properties of virgin material. There are hurdles still to overcome, but the new ...

The behavior of catalysts that promote chemical reactions is not always straightforward. For example, adding oxygen enhances some catalytic oxidation reactions (reactions that introduce oxygen ...

Noble metals such as platinum can make useful catalysts to accelerate chemical reactions, particularly hydrogenation (adding hydrogen atoms to a molecule). The research team led by Professor Bruce ...

Isobutylene is used in the chemical industry to make polymers for products ranging from footballs to cosmetics and to make high-octane gasoline additives. Surprisingly, the tungsten catalyst was even ...

This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate. The reaction produces a lot of heat so the substance shooting out of the bottle is water vapor that is ...
