Catalysis – Applied and Physical Aspects
نویسنده
چکیده
Large amounts of CO adsorption resulted from a pulse adsorption experiment at 323 K,giving ~300% Pt dispersion in the title catalyst.An in situ DRIFTS investigation showed that carbonate species on the Ce oxide surface are responsible for the CO adsorption, as a result of CO spillover. Lowering the temperature to 195 K reduced the amount of CO adsorption.The Pt particle size could be determined by CO pulse adsorption at 195 K.

Catalysis in nonlocal quantum operations.
We show how entanglement can be used, without being consumed, to accomplish unitary operations that could not be performed without it. When applied to infinitesimal transformations, our method makes equivalent, in the sense of Hamiltonian simulation, a whole class of otherwise inequivalent two-qubit interactions. The new catalysis effect also implies the asymptotic equivalence of all such inter...

متن کاملMechanistic aspects of enzymatic catalysis: lessons from comparison of RNA and protein enzymes.
A classic approach in biology, both organismal and cellular, is to compare morphologies in order to glean structural and functional commonalities. The comparative approach has also proven valuable on a molecular level. For example, phylogenetic comparisons of RNA sequences have led to determination of conserved secondary and even tertiary structures, and comparisons of protein structures have l...
متن کاملCatalysis seen in action.
Synchrotron radiation techniques are widely applied in materials research and heterogeneous catalysis. In homogeneous catalysis, its use so far is rather limited despite its high potential. Here, insights in the strengths and limitations of X-ray spectroscopy technique in the field of homogeneous catalysis are given, including new technique developments. A relevant homogeneous catalyst, used in...
متن کاملPhase-transfer catalysis for synthesis of ethyl 2-(4-nitrophenoxy)acetate under sonication- kinetic aspects
Ultrasound assisted phase-transfer catalyzed preparation of ethyl 2-(4-nitrophenoxy)acetate from the corresponding p-nitrophenol and ethyl 2-bromoacetate using the mild solid base, anhydrous potassium carbonate, under very mild conditions is reported. The solid-liquid reactions were performed in a batch reactor equipped with reflux condenser, and ultrasonic irradiations were introduced using an...
