Methods of Synthesis of Aluminum Particles and Aluminum Oxide Particles

The catalytic properties of some oxide ceramics and their solid solution derivatives are greatly dependent upon three main factors: particle size, structural distortion and chemical stoichiometry. In general, reducing the particle size of catalyst results in increasing its surface area and changing its morphology (e.g., from large pellets to spherical small clusters), thus, providing a larger number of more reactive edge sites.

Especially when the particle size is decreased below 100 nm, the materials become nanophase where the density of defects increases so that up to 50% of the atoms (molecules) are ...
