Abstract

A new concept to control catalysis and catalytic reaction through partial oxidation of alkenes with O2 is described. Oxidation of alkenes was studied by alkene/Pd-anode/H3PO4-electrolyte/cathode/O2 fuel cell (FC). An idea based on electrocatalysis and electrochemical reactions to control reaction rates and product selectivity was proposed and proven through the oxidation of propylene, Wacker and π-allyl oxidation. The oxidation rate and the product selectivity to the Wacker and the π-allyl oxidations could be controlled by changing electrode potentials. We could active control oxidation states of Pd on the anode, Pd(II) or Pd(0), during the oxidation from outer circuit. The oxidation states of Pd on the anode decided the product selectivity.
