Abstract
In this paper, the dispersion of Ag metal nanoparticles on SBA-15 mesoporous silica and its catalytic performance to oxidize glucose to gluconic acid were studied. Mesoporous silica SBA-15 materials were synthesized using the triblock copolymer Pluronic P123 as a template in acid condition. Ag nanoparticles were prepared using impregnation method inside the pores of the support by controlled reduction of AgNO3 with sodium borohydrate (NaBH4). The XRD, TEM, EDS, BET techniques were used for characterization of materials. Silver nanoparticle formation is confirmed by TEM. The efficiency of glucose oxidation to gluconic acid is determinated by HPLC-RID and LC-MS. Obtained results showed that it can prepare silver nanopartilces with particle diameter about 5 nm; and catalyst based on these particles has quite efficiency in glucose oxidation to gluconic acid.
