| Abstract |
The development of cost-effective electrocatalysts is critical in practical water electrolysis. While precious metal-based nanomaterials are strong candidates as catalysts due to their favorable intrinsic properties for hydrogen and oxygen evolution reaction (HER and OER), however, the issues of low natural abundance always remain for these materials. Furthermore, along with the cost issue, the long term stability of catalysts is indispensable requirement for practical application. In particular, while iridium-based nanoparticles have shown excellent initial catalytic performances toward OER, they have not shown acceptable level of long-term stability for practical application. In order to boost the catalyst stability, we have deposited iridium cobalt alloy on an inert CoxSy nanocage that deters the surface migration of iridium oxide phase during catalysis. Herein, we report iridium cobalt alloy on CoxSy nanocage as a bifunctional electrocatalysts for efficient water splitting catalysis. |
