Boron-modified ZrO₂ (B-ZrO₂) was synthesized under various pH values (9, 10, and 11) and used as the supports of PtSn catalysts (PtSn/B-ZrO₂-x) for non-oxidative dehydrogenation of propane. The NH₃-TPD and pyridine IR show that only Lewis acid is present and the acid strength increases with the synthesis pH. PtSn/B-ZrO₂-10 exhibits the best catalytic performance with an initial propane conversion of 36% and a deactivation rate constant (k_d) of 0.0127 h^-1. The XPS results indicate that the electronic properties of Pt and SnO_x are affected not only by their interaction but also by the interaction with support. After a careful analysis of the oxygen storage capacity and activity in CO oxidation, it is hypothesized that the interaction between Pt and Sn becomes stronger following the order:PtSn/B-ZrO₂-9 < PtSn/B-ZrO₂-11 < PtSn/B-ZrO₂-10. The characterization with TPO and Raman on spent catalysts exhibits that more hydrogen deficient coke forms on the support and less coke deposits on the metal surface of PtSn/B-ZrO₂-10. The results reveal that the interaction between Pt and Sn is influenced by their respective interaction with the support and a moderate interaction between the metal species and the support is desired.
