Silica, an oxide of silicon (silicon dioxide, SiO2), is easily synthesized with acceptable costs and shows some interesting properties. Based on the degradation of SiO2 in alkaline medium to ortho-silicic acid, silicon element can donate electron to an electron acceptor, which leads to the possibility of reduction reactions. In addition, silicon element can conduct electricity, which contributes significantly to the electron transfer or the electron carrier to receptors. Therefore, in this study, porous and nonporous silica particles were synthesized and investigated for indigo reduction through the presence or absence of another reducing reagent (i.e. glucose). The response of some synthesized silica particles to the reduction reaction of indigo was evaluated through their size, porous/non porous or functional groups and also compared with commercial fumed silica. |
