This study presents the fabrication of a Co3O4/CoS2 heterostructure for overall hydrazine-assisted water splitting using a facile and low-temperature hydrothermal technique. The structural analyses confirm the coexistence of Co3O4 and CoS2 phases with a significant interfacial interaction. The developed heterostructure exhibits superior electrochemical HzOR performance compared to individual Co3O4 and CoS2 phases.
This work reports the fabrication of a Co3O4/CoS2 heterostructure using a facile and low-temperature hydrothermal technique for overall hydrazine-assisted water splitting (OHzWS). The structural analyses using physical characterization techniques confirm the coexistence of Co3O4 and CoS2 phases with a significant interfacial interaction. The developed Co3O4/CoS2 heterostructure shows superior electrochemical HzOR performance compared to individual Co3O4 and CoS2 phases. It could deliver a current densities of 10 and 100 mA/cm2 at 240 and 340 mV, respectively. In addition, it delivers a high current density of 300 mA/ cm2 @ 480 mV without using any electrochemically active and expensive metallic substrate such as nickel foam, cobalt foam, etc. Furthermore, overall hydrazine-assisted water splitting by the Co3O4/CoS2 heterostructure required a low cell potential of 0.49 V, which is 1.35 V less than that for the overall conventional water splitting (10 mA/cm2 @ 1.84 V). Additionally, the heterostructured catalyst is stable for 3000 continuous
