Paper Abstract Zn-doped ruthenium oxides (Ru _1−xZn _xO ₂ (0 < x < 0.3)) shows unusual selectivity for oxygen evolution in presence of chlorides. The selectivity preference arises from clustering of the Zn ions in the blocks with ilmenite structure intergrowing with Ru-rich rutile blocks. Selectivity increase accompanies a drop in the catalytic activity.
