A hydrothermal approach has been employed for the synthesis of different morphologies of porous γ-AlOOH nanostructures. Mesoporous hydroxyapatite nanoparticles were synthesized using F127 Block copolymer as a soft template. For the first time, sucrose molecules were used as cosurfactant to alter the pore diameter in the mesostructured particles. Depending on the concentration of cosurfactant molecules, nanoparticles with pore diameters in the range of 50 - 96 nm were produced in this study. Furthermore, the results indicated that the use of cosurfactant molecules did not have any significant effects on the pore volume, surface area and morphology of the synthesized nanoparticles. The textural features of pore diameter, pore volume and surface area in the optimized mesoporous hydroxyapatite sample were 58 nm, 0.581 cm³∙g⁻¹ and 48 m²∙g⁻¹ respectively.
