Homogeneous catalysis
In chemistry, homogeneous catalysis is catalysis where the catalyst is in same phase as reactants, principally by a soluble catalyst in a solution. In...
Catalyst support
such cases, the catalyst support is usually in the form of pellets. Alternatively, supported catalysts can be prepared from homogeneous solution by co-precipitation...
Catalysis
only increase in the presence of the catalyst and never decrease. Catalysis may be classified as either homogeneous, whose components are dispersed in the...
Hydrogenation
in carvone using a homogeneous catalyst (Wilkinson's catalyst). Partial hydrogenation of phenylacetylene using the Lindlar catalyst. Hydrogenation of an...
Ziegler–Natta catalyst

Catalyst poisoning
will be evenly distributed throughout the catalyst and will result in homogeneous poisoning of the catalyst. Conversely, if the reaction rate is fast...
Grubbs catalyst

Crabtree's catalyst
Crabtree's catalyst is an organoiridium compound with the formula [C8H12IrP(C6H11)3C5H5N]PF6. It is a homogeneous catalyst for hydrogenation and hydrogen-transfer...
Catalytic oxidation
and homogeneous catalysis. In the heterogeneous processes, gaseous substrate and oxygen (or air) are passed over solid catalysts. Typical catalysts are...
