Identification of active sites in CO oxidation and water-gas shift over supported Pt catalysts.

Identification and characterization of catalytic active sites are the prerequisites for an atomic-level understanding of the catalytic mechanism and rational design of high-performance heterogeneous catalysts. Indirect evidence in recent reports suggests that platinum (Pt) single atoms are exceptionally active catalytic sites. We demonstrate that infrared spectroscopy can be a fast and convenie...

Active Sites and Mechanism for the Water-Gas Shift Reaction on Metal and Metal/Oxide Catalysts

Current industrial catalysts for the water-gas shift reaction are commonly mixtures of Fe-Cr and Zn-Al-Cu oxides, used at temperatures between 350-500oC and 180250oC, respectively. These oxide catalysts are pyrophoric and normally require lengthy and complex activation steps before usage. Improved catalysts are being sought, particularly for lower temperature (e.g., at T<150oC, equilibrium lowe...

FULL PAPER Active Sites in Olefin Metathesis over Supported Molybdena Catalysts

Metathesis of propene to ethene and 2-butenes was studied over a series of MoOx/SBA-15 catalysts (molybdenum oxide supported on mesoporous silica SBA-15; Mo loading 2.1~13.3 wt%, apparent Mo surface density 0.2~2.5 nm). The catalysts have been prepared by an ion exchange technique. Nitrogen adsorption, HMAS-NMR, Raman, and FTIR spectroscopies were applied to characterize the catalysts. Adsorpti...

The Selective Catalytic Reduction of NOx with NH3 over Titania Supported Rhenium Oxide Catalysts

Titania supported vanadium oxide catalysts have been demonstrated to be very efficient catalysts for the selective reduction of NOx with NH3 and have found widespread industrial application for the control of NOx emissions from stationary sources (1). Characterization studies have demonstrated that supported vanadium oxide catalysts consist of a two-dimensional metal oxide overlayer on the oxid...

Water-gas Shift Reaction over Ceria-promoted Pt catalysts

Introduction The fuel processor in which hydrocarbon fuels can be converted into hydrogen has recently attracted much attention as a result of the advancement in the fuel cell technology. In a fuel processor, the water-gas shift (WGS) reaction plays a crucial role in the transformation of CO, a well-known poisonous gas to electrode of fuel cell, into hydrogen through reaction with steam. In WGS...
