Adsorption Growth of SnO_2 Quantum Dot on the Surface of Sodium Titanate Crystal Fibers

In this paper, the adsorption growth characteristics of SnO_2 nanocrystals grown on the surface of sodium titanate crystal fibers were investigatived. The rutile structure SnO_2 nano-crystals quantum dot have been prepared on the surface of sodium titanate crystal fibers by the hydrothermal method using sodium titanate crystal fibers and proper amount of SnCl_4· 5H_2O as the precursors. The reaction conditions was pH value 11, the fill factor was 68%, reacting temperature were 120 ℃ and 150 ℃ respectively, the total reacting time was 24 h. The SnO_2 nano-crystals had a size of about 5 nm. The results show that the surface of sodium titanate had a strong apparent activation energy.
