Fabrication of Morphology of One-dimensional Nano-γ-AlOOH via Hydrothermal Route

One-dimensional nanostructure γ-AlOOH was fabricated via hydrothermal synthesis.And the effects of the processing parameters on structure of γ-AlOOH were investigated.The results show that γ-AlOOH nanorod can be achieved on the condition that AlCl3 density is lower than 0.2mol/L,pH value of reacting solution is lower than 7,and reacting temperature is set between 160℃ and 180℃;when pH value is higher than 7,γ-AlOOH is in the shape of nanoflake.Nanofiber with high slenderness ratio can be achieved on the condition that AlCl3 density is higher than 0.2mol/L,pH value is controlled between 5 and 6,and reacting temperature is set around 200℃ with adding surfactant SDBS.
