In order to synthesize cobalt-based spinel oxides, air was bubbled through aqueous hydroxides suspensions of cobalt and zinc with atomic ratios of Co:Zn=100:0, 85:15, 67:33 (precisely 2:1), 50:50, 30:70, 15:85, and 0:100 at 70掳C and atmospheric pressure. When cobalt was absent...

The mesoporous ZnxCo3-xO4fibers with average diameter are of 389.3nm and length up to 21.5渭m are synthesized by a facile hydrothermal process combined with a subsequent thermal treatment. The results show that they are composed of interconnected nanocrystals that can provide a continuous charge ...
When the ZnxCo3-xO4 polyhedron was employed as electrocatalysts for OER, a potential as low as 1.66 V (vs. RHE) was required to deliver the current density of 10 mA cm(-2) in 1 M KOH, and ZnxCo3-xO4 still presented superior activity after continuously working for cyclic voltammetric ...
