| Summary: | Title screen Composite AlN/Al nanoparticles were produced by the method of the electrical explosion of wire in a nitrogen atmosphere. The mass ratio of aluminum and aluminum nitride in the nanoparticles was regulated by the nitrogen pressure. Flower-shaped mesoporous pseudoboehmite (AlOOH) nanoparticles were fabricated by the reaction of composite AlN/Al nanoparticles with water. The kinetic regularities of the AlN/Al conversion in diluted aqueous suspensions at 60 C were studied. The effect of the mass ratio of aluminum and aluminum nitride in AlN/Al was shown. The flower-shaped AlOOH nanoparticles consist of nanopetals with a planar dimension of 150300 nm and a thickness of 510 nm. The flower-like structures have sizes of approximately 300600 nm. The increase in the mass ratio of aluminum nitride in AlN/Al results in an increase of the specific surface area of the pseudoboehmite nanopetals from 255 m2 /g to 330 m2 /g and an increase in the mesopore volume from 0.363 cm3 /g to 0.439 cm3 /g. The average pore size was 410 nm. The zeta-potential also increases from 32 mV to 46 mV with an increase in the mass ratio of aluminum nitride.
