Notes:
Nanosized TiO2-Ag-SiO2 sols were prepared with modified sol-gel method using reductionagent. The physical properties of the prepared particles were investigated by TEM, XRD and FT-IR.The titanium tetraisopropoxide (TTIP, 98% Aldrich), teraethylorthosilicate (TEOS, 98% Aldrich) andsilver nitrate were used as precursors of titania, silica and silver, respectively. Sodium citrate tribasicdihydrate (C6H5Na3.2H2O, Aldrich) was used as a reduction agent. This paper presents the effect ofnanosized TiO2-Ag-SiO2 sols on the formation of methane hydrate in a semi-batch vessel. Themicrographs of TEM showed that the TiO2-Ag-SiO2 particles possessed a spherical morphology witha narrow size distribution. The crystallite size of particles decreased with an increasing the SiO2content. In addition, the water solution with 1.0 wt% of TiO2-Ag-SiO2 particles acted as promoter formethane hydrate formation
