Description
<p>This paper shows the effect of the agglomeration control on the catalytic activity for oxygen evolution reaction (OER). In this study, (Ca0.5Sr0.5)RuO3 (CSRO) catalyst was selected as the bi-functional catalyst for OER and oxygen reduction reaction (ORR). The sol-gel derived CSRO particle was mixed with the carbon nano-particle in the tetrahydrofuran (THF) based solution under the various pH condition to prepare the ink for the air electrode of rechargeable metal-air battery. The microstructure of the air electrode was designed by controlling the electrostatic repulsion force of the CSRO catalyst particles in the ink. As a result, the surface area of the air electrode increased with increasing the electrostatic repulsion force of the CSRO catalyst particle, resulting in the enhancement of the OER activity. From these results, we concluded that the agglomeration control of the catalyst particle in the ink is one of the key factors to enhance the catalytic activities of the electrocatalysts.</p>
