AB  - Reduced graphene oxide (rG-O)-based materials have great potential as metal-free 
      electrocatalysts for the oxygen reduction reaction (ORR) owing to their 
      electrical and electrochemical properties and large surface area. Long-term 
      durability and chemical stability of the catalysts in the presence of 
      electrolytes such as aqueous KOH solution are important for their use in 
      practical applications. In this study, three types of rG-O and rG-O-K (rG-O after 
      reaction with KOH) materials were synthesized. The chemical structures, surface 
      areas, and catalytic ORR performances of the rG-O materials were compared with 
      those of the corresponding rG-O-K materials. The onset potentials of the rG-O 
      materials for electrocatalytic reduction of oxygen are almost the same as those 
      of the corresponding rG-O-K materials; however, the current density and the 
      number of transferred electrons are significantly reduced. These data show that 
      the catalytic ORR performance of rG-O-based materials can be altered by KOH.
