When: 27 August, 15:00
Dr. Simon Freakley (Bath) will give a seminar on production of H202.
Hydrogen peroxide has a key role to play in developing clean chemical processes. The direct synthesis of hydrogen peroxide from H2 and O2 would represent an attractive atom efficient process which could be decentralised as an alternative to the large scale anthraquinone process. Pd based catalysts have been extensively studied for this reaction however selectivity remains a key challenge to prevent the over-hydrogenation or decomposition of the H2O2 to H2O. This webinar will describe our work on developing Pd based catalysts for the synthesis of H2O2 which reach high levels of selectivity in both heterogeneous and electrochemical systems. In addition, the development of one pot reaction cascades which combine enzymatic peroxygenases and heterogeneous H2O2 synthesis catalysts to achieve challenging oxidation reactions at mild conditions will be discussed.
