摘要： The present invention relates to diesel oxidation catalyst compositions and catalyst articles, wherein the compositions and articles include a plurality of platinum group nanoparticles substantially in fully reduced form, wherein the nanoparticles have an average particle size of about 1 to about 10 nm and at least about 90% of the nanoparticles have a particle size of +/− about 2 nm of the average particle size. Such compositions can further include a refractory metal oxide material, wherein the nanoparticles and refractory metal oxide material can be combined within the same coating on a substrate or can be applied sequentially on a substrate. The nanoparticles can advantageously be substantially free of halides, alkali metals, alkaline earth metals, sulfur compounds, and boron compounds. Methods of preparing and using such compositions and catalyst articles (e.g., for the treatment of diesel exhaust gas streams) are also provided herein.

摘要： A hydrofluoroolefin is produced by reacting a chlorofluoroolefin with hydrogen in the presence of a platinum group metal catalyst supported on a carbon carrier to obtain a hydrofluoroolefin. The chlorofluoroolefin is represented by formula (1): CZX═CClY, where X is F or Cl, Y is F, Cl or H, and Z is F or CF3. The hydrofluoroolefin is represented by formula (2): CZX′ ═CHY′, where X′ is F when X is F, or X′ is H when X is Cl, Y′ is F when Y is F, or Y′ is H when Y is Cl or H, and Z is the same as Z in the formula (1). The carbon carrier has acidic functional groups, and the total acidic functional group amount in the carbon carrier is at most 50 μmol/g.

摘要： Catalytic materials, particularly membranes, exhibiting high activity, high stability and low metal leaching in a variety of chemical reactions, particularly selective hydrogenations of unsaturated organic compounds, are described. These membranes are inorganic/polymeric hybrid materials in which metal complex molecular catalysts are immobilized or metal nano-particle catalysts are embedded. More specifically, the catalytic materials of the present invention exhibit higher activity and selectivity, and can be used in more extensive kinds of organic solvents than the conventional hybrid catalytic materials due to improvement in the affinity to organic solvents by containing the specific polymeric additives.

摘要： Methods of sulfurizing metal containing particles in the absence of hydrogen are described. One method includes contacting a bed of metal containing particles with a gaseous stream comprising hydrogen sulfide and inert gas under reaction conditions sufficient to produce sulfided metal containing particles. The gaseous stream is introduced into a vertical reactor at an inlet positioned at the bottom portion of the reactor and any unreacted hydrogen sulfide and inert gas is removed at an outlet positioned above the inlet. The sulfided metal containing particles can be removed from the reactor and stored.
