Iron, Copper And Tin Incorporated Rice Husk Ash Silica: Preparation, Characterization And Application As Catalysts For Friedel-Crafts Benzoylation Reactions

Iron, Copper And Tin Incorporated Rice Husk Ash Silica: Preparation, Characterization And Application As Catalysts For Friedel-Crafts Benzoylation Reactions

Iron, copper and tin incorporated silica catalysts were prepared via sol-gel method using the silica extracted from rice husk ash. The modified catalysts were denoted as RHA-xFe (x = 5, 10, 15 and 20 wt.%), RHA-10Cu and RHA-10Sn. Prepared catalysts were characterized by various physico-chemical tec...
