| 英文摘要 | Recently, stable non-oxidative conversion of methane (NOCM) for up to 8 h with a C-2 selectivity greater than 90% has been reported over Pt-Bi/ZSM-5 at moderate temperatures (600-700 degrees C). In this study, we show that the structure of the bimetallic nanoparticles on Pt-Bi/ZSM-5 catalyst is similar to Pt-Bi/SiO2. EXAFS indicates the formation of Pt-rich bimetallic Pt-Bi nanoparticles with Pt-Bi bond distance of 2.80 A. The XRD spectra (on SiO2) are consistent with cubic, intermetallic surface Pt3Bi phase on a Pt core. The Pt3Bi structure is not known in the thermodynamic phase diagram. In all catalysts, only a small fraction of Bi alloys with Pt. At high Bi loadings, excess Bi reduces at high temperature, covering the catalytic surface leading to a loss in activity. At lower Bi loadings with little excess Bi, the Pt3Bi surface is effective for non-oxidative coupling of CH4 (on ZSM-5) and propane dehydrogenation (on SiO2). |
