Model systems for the study of active phase evolution in complex bimetallic catalysts (PdZn)
This study used PdZn as a model system to investigate phase transformations and its influence on reactivity. Aerosol synthesis was used to study the oxide precursors of the PdZn system, spin coating was used to synthesize model PdZn nanoparticles for phase transformations studies and preliminary …

Aerosol synthesis and Rietveld refinement of Pd2Zn
PdZn catalysts have been proven to be a viable option to replace current Cu catalysts for methanol steam reforming. The change in selectivity to CO2 that makes this a possibility has been attributed to the formation of tetragonal β1-PdZn at treatment temperatures of 500oC. Through the course of …

Development of bimetallic Pd-Zn catalysts for methanol steam reforming: hydrogen production for fuel cells
… difficult to handle. Recent studies show that PdZn catalysts are very promising as they exhibit comparable activity and selectivity to Cu-based ones. Furthermore, PdZn catalysts are thermally stable in the typically methanol steam reforming temperature range (200 - 300°C). Most literature …

Mechanistic insights into the direct synthesis of H2O2 on transition metal catalysts
… transfer mechanism is the same also on AuPd and PdZn catalysts. Among AuPd and PdZn catalysts, increases in the Au:Pd or Zn:Pd ratio leads to simultaneous but unequal increases in the activation enthalpies (∆H‡) for both H2O2 and H2O formation, which must result from significant electronic …

Novel routes for synthesis of Pd nanoparticles and faceted ZnO supports for heterogeneous catalysts
… the decomposition pathway, CH3OH --> 2H2+CO. PdZn alloys can achieve the desired selectivity, and have been noted to form under reaction conditions from Pd/ZnO heterogeneous catalysts. In the present work, careful synthesis techniques of specific support and nanoparticle surfaces have been …
