Abstract:
A set of model skeletal isomerization catalysts — sulfated zirconia nanoparticles of controlled thickness anchored on different supports — was prepared using colloidal solutions of Zr salt on titania as support. The nanoparticles of zirconia (1–5 nm) are epitaxially connected to the support surface, with S/Zr ratio equals to 1.3–1.5. It was shown by EXAFS that nanoparticles of non‐stoichiometric zirconium sulfate Zr(SO4)1+x, where x<0.5, are formed on the support surface. Its structure looks like half‐period shifted counterdirected chains built‐up by zirconium atoms linked by triangle pyramids of sulfate groups. Considering catalytic data of skeletal n‐butane isomerisation at 150°C, one can suggest that these species behave as the active component of sulfated zirconia. They are formed in subsurface layers as zirconium hydroxide undergoes sulfation followed by thermal treatment.
