Description:

In this project, we propose to design and study a new class of first-row transition metal (cobalt, copper, nickel and iron) catalysts for the reductive conversion of O2 to H2O2. The reactivity of these catalysts for selective two-electron reduction of O2 to H2O2 will initially be studied by electrochemical and chemical methods. The light-driven photochemical generation of H2O2 will then be investigated using the selected catalysts. In particular, the influence of metal active sites and their coordination environment on the catalytic properties, as well as the corresponding reaction mechanism will also be examined, so as to gain insight for the design of efficient systems for the photocatalytic generation of H2O2.
