The catalytic activity of a large group of catalysts used in isomerization, polymerization of alkenes, cracking, hydrocracking, dehydration of alcohols, manufacturing of alkyl ethers, reforming on bifunctional catalysts, and many other processes is due to the acidity of their surfaces. The knowledge of...
In this paper, we investigated the primary reduction and oxygen replenishing processes over Mn substitutionally doped CeO2(111) surfaces by density functional theory with the on-site Coulomb correction (DFT +U). The results indicated that Mn doping could make the surface much more reducible and ...
The selectivity to benzaldehyde is significantly enhanced at high conversions. It has been reported that the absolute thermoelectric power,S, of AuPd alloys is highly sensitive to the presence of unoccupiedd-band states58. As expected, the trends are similar for the catalytic activity, the entropy...
Formation, Characterization, and Catalytic Activity of Gadolinium Oxide. Infrared Spectroscopic Studies Gd2O3 was obtained as a final product of the thermal decomposition of Gd(CH3COO)(3).4H(2)O. The decomposition processes up to 800 degrees C were characteri... Hussein,AM Gamal - 《Journal ...
Here we show how catalytic activity and promiscuity in a self-replicator emerges through co-option: features that are selected to benefit replication inadvertently result in an arrangement of chemical functionalities that is conducive to catalysis. Specifically, we report self-assembly driven self-...
The latter act as coordinatively unsaturated sites-a hypothesis introduced long ago to account for the catalytic activity of oxide surfaces-onto which carbon monoxide can chemisorb and from where it can react with neighboring lattice-oxygen to carbon dioxide. Under steady-state conditions, the ...
