Catalysts. vol: 11. page: .
Date: MAR. 2021.
Doi: 10.3390/catal11030337.

Abstract:
Two commercial activated carbon were functionalized with nitric acid, sulfuric acid, and ethylenediamine to induce the modification of their surface functional groups and facilitate the stability of corresponding AC-supported iron catalysts (Fe/AC-f). Synthetized Fe/AC-f catalysts were characterized to determine [read more]
