Synthesis of Bimetallic Au-Ag/CMK‑3 Catalysts
and Their Catalytic Activity for the Oxidation of Amino Alcohol
Posted on 2020-08-05 - 19:03
CMK-3 supported highly dispersed
Au-Ag bimetallic nanoparticles
with different Ag/Au ratios were prepared by a sequential impregnation–reduction
method without the use of any polymer stabilizer. The physicochemical
properties of these catalysts were characterized with XRD, ICP-OES,
EDS, TEM, XAFS, XPS, STEM, and H2-TPD. The introduction
of Ag influenced the surface Ag/Au ratios, particle size, and electronic
and structural properties. The relationship between the desorption
amount of H2 and the ideal atomic arrangements with different
Ag/Au ratios on the (111) planes revealed that the isolated atomic
sites on the surface of alloy nanoparticles significantly improved
the ability of hydrogen dissociation and the catalytic activity. As
a result, compared with the monometallic Au/CMK-3, the conversion
of monoethanolamine catalyzed by 10Ag90Au/CMK-3 could increase by
23% and the apparent activation energy was reduced by 10.9 kJ·mol–1.
