Comparative Study of Acid and Base-Treated Ordered Mesoporous Carbon-Supported KCoRhMoS2 Catalysts for Higher Alcohols Synthesis

Chemical treatments of ordered mesoporous carbon using HNO₃, NH₄OH/H₂O₂ and KOH evidenced severity trend: HNO₃>NH₄OH/H₂O₂>KOH. Catalytic performance evaluations at similar reaction conditions showed superior total alcohol productivity for HNO₃-treated supported-OMC catalyst as compared to its NH₄OH/H₂O₂ and KOH counterparts; probably due to the greater number of surface oxygen-containing functional groups.
