A modified mesoporous silica optical nanosensor for selective monitoring of multiple analytes in water.
نویسندگان
چکیده
A new modified mesoporous silica nanosensor was synthesized by the co-condensation method. Under basic conditions, the obtained mesoporous silica nanosensor responds selectively to Fe(2+) (pH = 8) and Cu(2+) (pH = 12) with a distinguishable colour change perceivable by the naked eye and a detection limit of approximately 50 ppb.

In this study, highly ordered mesoporous silica material (SBA-15) functionalized with Diethyl 2 - (9 -fluorenyl) malonate as a flourophore is reported. The anchoring of flourophores to the hydroxyl group on SBA-15 surface was done with post synthesis method. The obtained materials were characterized by small and wide angle X-ray diffraction, N2 adsorption–desorption, Fourier transform infrared ...

متن کاملNanosized mesoporous composite PW12-APTES@KIT-6: An efficient heterogeneous catalyst for selective oxidation of sulfides to sulfoxides and sulfones
Surface of mesostructured silica, KIT-6, was modified by grafting 3-aminopropyl-triethoxysilane (APTES) to have the positive charge, and thus, to provide sites for the immobilization of H3PW12O40 (PW12). This modified-nanosized mesoporous silica (PW12-APTES@ KIT-6) was characterized by FTIR, XRD, BET and TEM. The oxidation of sulfides occurs effectively and selectively with H2O2 as the oxidant...
