Porous γ-AlOOH Nanoparticles Synthesized via Hydrothermal Route at Low Time

Under hydrothermal conditions, we prepared mesopores γ-AlOOH nanoparticles by changing the adjusting pH in low time of reaction mixture at 200 °C. The role of NaOH and KOH as adjusting pH on the formation of γ-AlOOH was investigated. The resulting products were characterized by X-ray diffraction (XRD), Fourier transform-infrared spectra (FT-IR), field emission scanning electron microscopy (FESEM), transmission electron microscopy and N2 adsorption desorption analysis. Our result showed that using KOH as adjusting pH in the constant conditions can be formed γ-AlOOH nanoparticles, but with NaOH, this product was not formed completely. The present nanoparticles with distinctive size and shape features might open up promising applications in many fields due to high crystallinity and surface area.
