The synthesis of TiO2
nanopowder required magnetic stirring at medium speed.
Then, the inorganic Sm/Ag/TiO2 nanomaterials was
synthesized by mixing the powders of Ag, the rare-earth
Sm, and TiO2 in a muffle furnace (SX2 12-2.5) and then
heating the mixture to different temperatures. Finally, the
supercritical fluid extraction technique was used.
