The electrochemical behavior of the modified electrodes: a Nikko Keisoku DPGS-1 dual potentiogalvanostat and a NFG-3 universal programmer were employed along with a Graphtec WX2400 X-Y recorder to obtain the voltammogram. The samples and electrolytes were set up in a conventional two-compartment cell in which a glassy carbon disk electrode served as the working electrode. The counter electrode was a platinum wire and the reference electrode was a saturated calomel electrode (SCE). , it was demonstrated that the vanadium multinuclear complex catalyzes the reduction of O2 at a high potential, which is promising to expand the wide application of the catalyst. Although the mechanism of this vanadium-based cluster complex 1 was not yet clarified, the oxophilic [V(III)] of oxovanadium(V) cluster complexes were predicted actively reacts with O2 to accomplish a four-electron reduction of O2 in acid condition as described in previous literature (2[V(III)] / O2/ 2[V(V)O]).
