Description
Summary:Herein, we report Co3O4/PPy hierarchical structures as electrode materials grown on nickel foam by a facile strategy. The as-obtained Co3O4/PPy products show high catalytic performances. [Display omitted] In this work, we report Co3O4@PPy hybrid structured electrode materials for overall water splitting. The as-synthesized Co3O4/PPy-120 samples present excellent electrocatalytic performances for OER and HER and long durability. It only requires an operating potential of 1.67 V to deliver a current density of 10 mA/cm2 with a remarkable durability for 28 h. The superior electrocatalytic performances mainly can be attributed to the unique heterostructures and the synergistic effects between PPy and Co3O4 electrode materials.
