촉매 합성에 사용된 에틸렌글리콜의 양 변화에 따라 촉매의 활성도가 다름을 확인할 수 있었고, PdCu/C 촉매 합성 시 용매로 사용된 에틸렌글리콜 양의 최적 용량이 있음을 확인할 수 있었다.
It was confirmed that the activity associated with the catalyst had been different based on the alteration in the total amount of ethylene glycol useful for catalyst synthesis, and it had been confirmed that there is an optimal capacity of this amount of ethylene glycol used as a solvent in the synthesis regarding the PdCu/C catalyst.
