Monometallic Pt and bimetallic Pt-Sn catalysts were prepared by incipient wetness impregnation. Impregnation solutions were prepared by dissolving appropriate amounts of Pt(NH 3) 4 (NO 3) 2 (Johnson-Matthey/Aesar) and SnCl 2 ·2H 2 O (Merck, 98–) in double deionised water. The resulting solution was added dropwise to the …

Catalyst deactivation by coking is one major problem for propane dehydrogenation (PDH). To develop catalysts with high resistance to coke, the analysis of coke becomes essential. In this work, an analysis procedure is proposed and validated to acquire the detailed locations and compositions of the coke formed on an as-synthesized …
ITO is considered as a support for Pt, catalysing ... Appl. Electrochem. 45, 1165–1173, doi:10. ... W. E. Stability limitations for Pt/Sn–In2O3 and Pt/In–SnO2 in acidic electrochemical ...
These results indicate that the excessive addition of K weakens the interactions between Sn species and ZSM-5 carrier obviously, thus making the reduction of Sn species to form Sn 0 easily. According to Tasbihi et al., the addition of K and Sn to Pt led to a direct interaction between these metals. Therefore, it can be concluded that the ...
Catalytic reforming of n-heptane over a series of Pt-based catalysts modified by Sn and Ce has been conducted in a fixed-bed reactor.Introducing Sn and Ce resulted in changes in the electronic environment of the Pt particles and acidity properties of the γ-Al 2 O 3 support, causing changes in product distribution. Results from in-situ Diffusion …

The catalytic performance of PtSnZn/Al2O3 is also significantly higher than that of Pt/Al2O3, PtSn/Al2O3, and PtZn/Al2O3. Experiments and theoretical calculations indicate that the Sn 5p and Zn 4s orbitals are hybridized with Pt 5d by forming Pt−Sn and Pt−Zn pairs, which leads to the d band center of Pt deviating from Fermi level (−2.81 eV).
However, due to its high SN for VT, its overall accuracy was similar to those of the other algorithms. The original report stated SP and SN values of 96 and 64%, respectively, 6 whereas the present values were lower. Similarly, Lau et al. 10 reported a lower SP for this algorithm (44%) than originally described.
The bright field TEM images displayed in Fig. 1 show the distribution of NPs on the silica support. The mean particle sizes of the Pt/SiO 2 and Pt–Sn/SiO 2 catalysts are summarized in Table 1.The data shows that the oxidative atmosphere led to poor Pt dispersion on Pt/SiO 2 catalysts. Large NPs (∼26 nm) were observed, whose particle …
In the present study, the applicability of a bimetallic Pt-Sn/Al2O3 in propane dehydrogenation with different promoters, namely, Ca, Mg, and incorporation of Mg-K and Ca-K was studied. The catalysts were prepared by the sequential impregnation of γ-alumina support and characterized by TPD, SEM, XRD, and UV analysis. The propane …
