WebBriefly, 1 mL of aqueous solution containing the nanoparticles (1 mg/mL), 10 μL of a SnCl 2 2H 2 O solution (diluted in 0.25 N HCl 1 mg/mL), and 10 μL of a NaHB 4 solution (diluted in 0.25 N NaOH 5 mg/mL) were added to a vial, with the pH adjusted to 7.0. After, the vial was sealed, and a vacuum was made. WebTin precursor (SnCl 2 · 2H 2 O, m.p. 310-311 K) was infiltrated spontaneously within the mesopores of silica templates by melting the precursor at 353 K without using any solvent. The heat-treatment of SnCl 2 -infiltrated composite materials at 973 K under static air conditions and subsequent removal of silica templates by using HF result in the …
