Au/TiO2 supported on ferritic stainless steel monoliths as CO oxidation catalysts
(Elsevier, 2013-01)
Metallic supported structured catalysts were obtained by washcoating AluchromYHf monoliths with an Au/TiO2 catalyst. The powder catalyst was synthesized by DAE (direct anionic exchange) method. Using this catalyst, a stable ...
Síntese direta do acetato de etila a partir do etanol sobre catalisadores de Au, Cu e AuCu suportados em zircônia monoclínica (m-ZrO2)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2018-03-09)
The ethanol conversion into ethyl acetate is a very important reaction, in economic and scientific fields. In the context of science, the propose of this work was to evaluate the activity of Au and Cu catalysts supported ...
Hydrogenation of nitrobenzene on Au/ZrO2 catalysts
(Sociedad Chilena de Química, 2012-06)
The hydrogenation of nitrobenzene at 298K and pressure of 40 bar of H2 over zirconia supported Au catalysts has been studied. Three different procedures were used to prepare 1wt% of Au/ZrO2 catalysts: i) An impregnation ...
Effect of Au doping of Ni/Al2O3 catalysts used in steam reforming of methane: Mechanism, apparent activation energy, and compensation effect
(2019-11-02)
Investigation was made of the effect of addition of Au to 15%Ni/Al2O3 catalysts used in the steam reforming of methane. The addition of Au was performed by impregnation of reduced Ni catalysts. The catalysts were characterized ...
Pt catalysts supported on ion exchange resins for selective glycerol oxidation. Effect of Au incorporation
(Elsevier Science, 2017-05)
In this paper, bimetallic Pt-Au catalysts were studied for the selective liquid phase oxidation of glycerol. The support used was a macroporous weak anion exchange resin. Two different preparation methods were employed: ...
Ammonia borane dehydrogenation tendencies using Pt4, Au4, and Pt2Au2 clusters as catalysts
(Elsevier B.V., 2019)
Small metallic clusters -mediated gas phase catalysis studies give lights to understand simple and complex catalytic processes, and help in the discovery and explanation of non-traditional “molecular-scale” catalytic ...
XAS study on the gold particle size of Au catalysts
(Brazilian Synchrotron Light Laboratory, 2010-12)
In the last few years, gold catalysts have generated a great amount of interest. This has been the result of two main findings: gold is the most active catalyst for ethyne hydrochlorination, and it is also effective for ...
Photocatalytic hydrogen production over titania modified by gold – Metal (palladium, nickel and cobalt) catalysts
(Elsevier, 2016-12)
The photocatalytic production of hydrogen on modified Au/TiO2-based photocatalysts by using water/methanol mixtures was studied. The main goal was to study the effect of surface modification of Au/TiO2 with Pd, Ni and Co ...
