Electrocatalytic oxygen production is an independent actual task. In recent years, the ho mog en eou s catalysis of water oxidation (WOC) has also been actively developed, with the use also the "iron triad", in particular nickel -in neutral and in alkaline media (see recently published detailed review ). It is reasonable to perform here the NELTO-electro-oxidation of alcohol in a heterogeneous system (see above) + homogeneous WOC catalyst, to evaluate the extent of the activity zone of the heterogeneous catalyst.
