In the present study, highly disperse silica-supported titania zirconia nanocomposites were synthesized by a liquid-phase method.
The presence of chemisorbed water allows one to stabilize Pd in highly disperse state thus preventing the catalyst deactivation.
The centroid method identifies groups as highly disperse under these conditions, because some pedestrians can be far from the centre of the group.
A method of grafting of mixed oxides onto a surface of highly disperse matrices with nonporous nanoparticles can be a good alternative to the mentioned methods.
The results showed that La2O3 derived from the La2O2CO3 precursor maintained its initial morphology upon thermal treatment and could highly disperse Ni particles on it.
In addition, the CoMn catalyst obtain derived from hydrotalcite precursors presented great stability for keeping active site highly disperse on the layer during the long reaction time.
The spectroscopic properties of these dye-doped nanocomposite materials suggest a silica/block-copolymer/dye co-assembly process, whereby the block-copolymers help to highly disperse the organic dye molecules.
Whereas, the grafting method could highly disperse Pd nanoparticles within the mesoporous channels of support material, and the grafting procedure should be promising in designing highly dispersed Pd particles on the silica-based mesoporous materials.
