| 제목 | Design of Ru-based oxygen evolution reaction (OER) electrocatalyst with efficient catalytic activity and stability |
| 초록 | Clean energy is attracting attention as a solution to the current energy economy system problems caused by fossil fuels. On that point, hydrogen resources produced by electrochemical water splitting have advantages of no pollution for operations and high energy density and so on. There have 2-electrochemical reactions on the electrochemical water splitting system; hydrogen evolution reaction (HER) on cathode and oxygen evolution reaction (OER) on anode. Ruthenium (Ru) element is known promising catalyst because it can achieve high performance, but there has a decline of durability caused by dissolution. To improve that issue, we focused on modification of the electronic structure of Ru based electrocatalysts by introducing platinum (Pt). Especially, on accout of RuO2 and PtO2 have structurally similarity, which can change the electrochemical structure without crystal structural strain. As a result of designing of catalysts system, enhanced stability can be interpreted. |
