Oxidative Splitting

Herein, we discuss recent research activities on the electrochemical water/CO2 co-electrolysis at the Department of Chemistry and Biochemistry of the University of Bern (Arenz and Broekmann research groups). For the electrochemical conversion of the greenhouse gas CO2 into products of higher value catalysts for two half-cell reactions need to be developed, i.e. catalysts for the reductive conversion of CO2 (CO2RR) as well as catalysts for the oxidative splitting of water (OER: Oxygen Evolution Reaction). In research, the catalysts are often investigated independently of each other as they can later easily be combined in a technical electrolysis cell. CO2RR catalysts consist of abundant materials such as copper and silver and thus mainly the product selectivity of the respective catalyst is in focus of the investigation. In contrast to that, OER catalysts (in acidic conditions) mainly consist of precious metals, e.g. Ir, and therefore the minimization of the catalytic current per gram Ir is of fundamental importance.

Oxidative Splitting

During the reaction of haemoglobine with nitrosobenzene, the latter was determined polarographically. Nitrosobenzene bound by coordination to the divalent Fe atom of haemoglobine was polarographically inactive; it was set free from this complex by oxidation of the iron with ferricyanide and then determined. At a molar ratio of nitrosobenzene to haemoglobine of 4 : 1, at which the molar ratio of iron to nitrosobenzene is 1 : 1, 0.9 mol of nitrosobenzene is bound by coordination to the iron while 0.1 mol is reduced by SH groups to azo- and azoxybenzene. After the SH groups of haemoglobine had been blocked by cyanoethylation or oxidation, nitrosobenzene was bound to iron in a stoichiometric ratio. Accordingly, the conditions for the polarographic determination of nitrosobenzene after oxidative splitting of the complex with haemoglobine are defined.
