and optimizing the catalyst preparation.Based on a villiform spherical TiO2 with the largest specific surface area in our experiments,we prepared a set of catalysts with various loading amounts of palladium......
to a decrease of the Ce-O bond strength. Pd-Ce synergism affects the reduction behavior of the catalysts. The TPR results show that the CeO2 addition lowers the reduction temperature of PdO, while palladium......
declined and became essentially the same. CO chemisorption results revealed that the suppressed activities of the aged catalysts were mainly due to the decline of palladium dispersion. The turnover......
of selenium,tellurium,gold,platinum,and palladium are 0.7825%,5.492%,8.333%,0.2587%,and 1.113%,respectively; the precious metals are enriched approximately sixfold.关键词:......
was very stable through the palladium salt test. There was no phenomenon of peeling and blistering on the surface of the Ni-W-P alloy glass fibers in the thermal shock test. It showed that the deposit had......
palladium as a surface catalyst.The influence of catalyst activation conditions on coatings’ properties was assessed by structural,morphological,electrical,mechanical measurements and adhesion......
in wetting reaction between Sne3.0Age0.5Cu solder balls and electroless nickel electroless palladium immersion gold(ENEPIG) pads at 250 C was investigated. The interfacial IMCs transformed from initial......

inhibited agglomeration of palladium, increased the number of active sites of Pd, and improved the electrocatalytic properties of Pd for ethanol oxidation.In addition, the Pd/Ni O/NFF loaded Pd catalyst......
was characterized by means of X-ray diffraction, adsorption and de-sorption. The cerium zirconium catalyst was obtained by palladium metal impregnation techniques. With methane catalytic combustion.... The catalytic activity of palladium supported cerium zirconium catalyst is high, whose light-off temperature is as low as 352℃. Key words: cerium zirconium mixed oxides; high surface area; good thermal......
