Jons Jacob Berzelius discovered the chemical phenomena of catalysis in 1835 and he confirmed that the rate of reaction can be affected by the presence of any chemical substance. Example: If KClO 3 ...

The domination of metals in catalysis is under threat as organic catalysts gain ground. The latest example may expand chemical reactivity beyond the achievements of traditional metal complexes.

Types of Catalysts. There are two main types of catalysts used for catalysis; heterogeneous or homogeneous. A heterogeneous catalyst acts in a different phase to its reactants, whereas a homogeneous ...

Catalysis: They are essential in catalysis, particularly in processes like hydrogenation, hydroformylation, and polymerisation. For example, Ziegler-Natta catalysts, which are organometallic ...

Catalysts are therefore used in the chemical industry to make manufacturing processes more economical. Some examples of catalysts used in industry are: Iron – used to make ammonia by the Haber ...

This includes patents where a catalysis development has been protected and/or used in an applied process. Sustainable or Green credentials. Any examples where this supports sustainable or improved ...

As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the ...
