Hi everyone!
I'd thought id start a thread about the pre-release booklet where we can look at possible questions etc.
This years is titled 'Catalysis'
You can find it here....

Let's get this thread started again..! I have a question, anyone want to explain to me what the hell a Ziegler Natta catalyst is? The pre-lease doesn't make it very clear in my opinion

So do we all agree that the heterogeneous catalyst is an a different physical state to the reactants whilst the homogeneous catalyst is in the same physical state to the reactants?

examples of homogeneous catalysts are:
-Enzymes
-Ziegler-Natta polymerization
-Hydrogenation
-Transfer hydrogenation
-Hydroformylation

homogeneous catalyst is usually in gas and liquid state while a heterogeneous catalyst surface tends to be in a solid state
