This study compared properties of silica (SiO2) from rice husk (RH) and rice husk ash (RHA) extracted by acid- and heat-treatment. The SiO2 from RH was in amorphous phase with nearly 100% purity while that from RHA was in crystalline phase with 97.56

The surface Nafion®XL membrane, which suffered from photo-degradation by various VUV irradiations fluences, was investigated by photoemission spectroscopy. After VUV light exposure, the fluorine was dissociated and the C C double bond was then measu

The goal of this work was to utilize rice husk silica (RHS) and porous materials synthesized with RHS, including mesoporous material (MCM-41) and microporous materials (zeolite NaY and NaBEA), for adsorption of herbicide paraquat. The adsorption occu

Zeolite Y in sodium form (NaY) was synthesized using silica source from rice husk, transformed to ammonium form (NH 4 Y), and calcined to convert to proton form (HY). The direct conversion of NH 4 Y to HY resulted in loss of the zeolite crystallinity
