A Sacrificial Coating Strategy Toward Enhancement of Metal-Support Interaction for Ultrastable Au Nanocatalysts.
Supported gold (Au) nanocatalysts hold great promise for heterogeneous catalysis; however, their practical application is greatly hampered by poor thermodynamic stability. Herein, a general synthetic strategy is reported where discrete metal nanoparticles are made resistant to sintering, preserving their catalytic activities in high-temperature oxidation processes. Taking advantage of the uniqu...
متن کاملInfluence of TiO2 bulk defects on the CO adsorption and CO oxidation on Au/TiO2 – Electronic metal-support interactions (EMSI) in supported Au catalysts
Electronic metal-support interactions (EMSI) are demonstrated to severely affect the CO oxidation activity and the CO adsorption properties of Au/TiO2 catalysts. Bulk oxygen vacancies, generated by a strongly reductive pre-treatment of Au/TiO2 at elevated temperature in 10% CO/N2, significantly lower the catalytic activity for CO oxidation at 80°C. With time on stream, the activity slowly incre...
متن کاملCharacterization of metal clusters (Pd and Au) supported on various metal oxide surfaces (MgO and TiO2)
Au clusters supported on the TiO2~001!/Mo~100! surface and Pd clusters supported on the MgO~100!/Mo~100! surface have been studied using temperature programmed desorption, ion scattering spectroscopy, scanning tunneling microscopy, and scanning tunneling spectroscopy. Three dimensional growth has been observed at 300 K for both cases. The adsorption energy of Au on the TiO2~001! surface has bee...
متن کاملNaphthalene hydrogenation over Pt/TiO2–ZrO2 and the behavior of strong metal–support interaction (SMSI)
Vapor-phase naphthalene hydrogenation over various supported Pt catalysts was studied in a continuous fixed-bed microreactor. Experimental results indicated that the catalytic activity of the catalyst strongly depended on the nature of the support and the pre-reduction temperature. Reaction order was independent of the support as the reaction was pseudo-first-order with respect to naphthalene i...
متن کامل‘‘Catalytically active Au on Titania’’: yet another example of a strong metal support interaction (SMSI)?
In light of the many similarities between previous studies of the so-called strong metal support interaction (SMSI) involving Gr. VIII metals, and catalytically active Au, it is apparent that these two phenomena must be closely related. That active Au on titania spreads to form a bilayer structure, is electron-rich as determined by theory and experiment, nucleates on reduced Ti defects created ...
