The structural features, texture and surface properties of highly dispersed partially substituted framework zirconium phosphates synthesized via sol-gel or mechanochemical activation route followed by the hydrothermal treatment in the presence of polyethylene oxide were studied and compared with catalytic properties in the pentane and hexane isomerization. The most efficient promoter was found to be Si which increases the surface density of the Broensted Zr-OH centers. Pt-supported Si-modified systems demonstrate promising activity and selectivity in propane and hexane hydroisomerization at 300-400 °C.
