□연구개요(Purpose & summary)
We proposed a development of low cost multifunctional electrocatalysts through hybrid structured layered materials for efficient energy conversion devices. In last three years, we have synthesized and measured electrocatalytic activity of various layered materials based on transition metal derivatives. We have shown that via hybridization of active and conductive materials, we can develop a bi-functional electrocatalysts in alkaline electrolytes. We have also shown that via different architecture of transition metal derivatives we can get the mass producible electrocatalysts for hydrogen production.

□연구 목표대비 연구결과(Results compare to proposal)
We proposed that we will develop multifunctional electrocatalysts based on layered materials for hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). In last three we have developed various kind of electrocatalysts for HER, OER and ORR. We developed transition metal chalcogenides (TMCs) based bi-functional electrocatalysts for ORR and OER together in alkaline medium. However, we have developed a 3-dimensional (3D) transition metal phosphide for bi-functional electrocatalysts for HER and OER together in alkaline and acidic medium. We proposed to publish 1 SCI paper per year. We have published nearly 3 papers per year on this typic with acknowledge of this fund.

□연구개발결과의 중요성(Importance of this research&results)
Our research would help to improve the research in electrochemistry. We gave a different way to design new materials for doing research in electrochemical energy conversion systems. We proposed a multifunctional electrocatalyst materials towards highly efficient energy conversion systems which are extremely desirable to fulfil the needs of and further the utilization of sustainable energies in the new technology. We developed an alternative low-cost multifunctional material which showed the many advantages enabled by designing highly-active and durable electrocatalysis. Our research present new efficient catalysts for energy conversion systems which is distinct from those in previous conventional high cost and noble metals as catalytically active sites to construct effective electrocatalysts.
