Debye Colloquium

Debye Colloquium - Catching transient intermediates in homogenous oxidation catalysis

This Debye Colloquium, Catching transient intermediates in homogenous oxidation catalysis, will be given by prof. dr. Wesley Browne from Groningen University.

The search for new and better reactivity has driven the development of first row transition metal catalysis over the last several decades, not least in the field of oxidation catalysis. Professor Browne's group has focused on manganese and iron based catalysts for both fine chemical and bulk applications, and more recently on Ni(II) based catalysts, employing environmentally benign oxidants. A key challenge faced in catalyst development and in optimisation is to move from catalyst discovery to catalysis design. However, design requires understanding of the fundamental mechanisms that underpin the catalysis observed and the interplay of all reaction components. This lecture will focus on efforts to track the formation and decay of transient intermediates using time resolved UV-vis and (resonance) Raman spectroscopy and establish their relevance to the catalytic activity observed. In particular the challenges presented by mass transport and sampling rate in obtaining useful kinetic information will be commented on.

There will be drinks afterwards.
