Aromatization of butane on Pt–Ge intermetallic compounds supported on HZSM-5

STM and LEED observations of a c(2 × 2) Ge overlayer on Pt(1 0 0)

“…In particular, for supported catalysts, the addition of Ge to Pt-loaded HZSM-5 improved the selectivity of butane dehydrogenation to aromatic hydrocarbons [3]. Also, Pt-Ge intermetallic compounds gave high selectivity for the partial hydrogenation of 1,3-butadiene [4].…”

“…Bimetallic Pt-Ge interfaces and surfaces of Pt-Ge intermetallic compounds are of interest for research and applications in a variety of areas, including electronic devices and detectors [1,2], Pt-based heterogeneous catalysts [3][4][5][6], and electrocatalysts for fuel cells [7,8]. In particular, for supported catalysts, the addition of Ge to Pt-loaded HZSM-5 improved the selectivity of butane dehydrogenation to aromatic hydrocarbons [3].…”

Suppressed surface alloying for a bulk miscible system: Ge on Pt(100)

“…8 On Pt͑111͒, the addition of even low concentrations of Ge alters the chemical properties of the surface. [9][10][11][12] Herein, investigations of the Ge/Pt͑100͒ system are reported. We found that Ge alloying is suppressed for low Ge coverages on this surface.…”

Relationship between the molybdenum phases and the conversion of n-butane over Mo/HZSM-5

“…As a solution, Ga or Zn is inserted into the framework of HZSM-5, but this leads to the decrease in the activity. It is reported that H-Ga (or Zn, Ge)-ZSM-5 [38][39][40][41] modified by Pt gives optimal results despite that n-C 4 H 10 is seriously cracked on Pt/HZSM-5 [22,41].…”
