Amorphous silica from sugarcane bagasse ash (Si-BA) was extracted and used as a support for iron (Fe). The FeSO4 was loaded onto the Si-BA by 3 different methods consisting of refluxing (RF), incipient wetness impregnation (IWI) and physical mixing (

Rice husk silica (RHS) and NaY were used as supports for potassium (K) prepared from acetate buffer (B) and acetate (A) solutions. K loading did not destroy the NaY structure, but it caused a decrease in the surface area; the K species resided in mic

In this study, Fe loaded zeolite NaY with varying iron contents was prepared and used as glyphosate adsorbents. A hydrothermal method was used to synthesize the zeolite NaY from bagasse ash derived silica (Si-BA). Various Fe contents (1.75 - 7.66 %w/

An attempt to decrease coke formation from phenol hydroxylation on iron catalyst supported on zeolite beta (Fe/HBEA) was investigated. HBEA was dealuminated by refluxing in nitric acid. The dealumination removed all framework aluminum atoms and presu

Iron (Fe) was loaded on zeolite beta (BEA) in ammonium (NH4BEA) or proton (HBEA) forms by various methods. Fe/HBEA-LSIE and Fe/NH4BEA-LSIE were prepared by liquid state ion exchange (LSIE). This method resulted in low Fe loading and a good dispersion
