STUDY ON THE SYNTHESIS OF MESOPOROUS CERIA IN THE PRESENCE OF GLUCOSE AND ACRYLAMIDE
(Sociedad Chilena de Química, 2009)
Gold nanoparticles supported in zirconia-ceria mesoporous thin films: A highly active reusable heterogeneous nanocatalyst
(American Chemical Society, 2015-01)
Gold nanoparticles (NP) trapped in the mesopores of mixed zirconia-ceria thin films are prepared in a straightforward and reproducible way. The films exhibit enhanced stability and excellent catalytic activity in nitro-group ...
Rapid preparation of block copolymer templated mesoporous Zr1-xCexO2 thin films
(Royal Society of Chemistry, 2017-05)
A scalable, simple, robust and reproducible method is presented for the preparation of chemically homogeneous and ordered nanocrystalline and mesoporous Zr1-xCexO2 thin films. The method utilizes widely available commercial ...
A general method to produce mesoporous oxide spherical particles through an aerosol method from aqueous solutions
(Springer, 2019-11-15)
Mesoporous transition metal oxides (MTMO) with large surface area, nanocrystalline framework, and controlled porosity have brilliant prospects in fields such as energy, environment, catalysis, or nanomedicine. However, the ...
Structural studies of mesoporous ZrO2-CeO2 and ZrO2-CeO2/SiO2 mixed oxides for catalytical applications
(Elsevier Science Sa, 2016-06)
In this work the synthesis of ZrO2-CeO2 and ZrO2-CeO2/SiO2 were developed, based on the process to form ordered mesoporous materials such as SBA-15 silica. The triblock copolymer Pluronic P-123 was used as template, aiming ...
Evaluación de un catalizador de Níquel-Ceria en la reacción de metanización de dióxido de carbono
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2017)
En este trabajo se presenta el estudio de la reacción de metanización de CO₂ en fase gas empleando como catalizador Ni/CeO₂. Se sintetizó el soporte (CeO₂) por medio del método de plantilla dura y se agregó Ni al 5% en ...
Producción de H₂ mediante reformado de etanol en fase vapor empleando catalizadores Ni/γ-AL₂O₃ modificados con La₂O₃-CeO₂
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2018)
El objetivo de este trabajo fue estudiar el efecto sinérgico entre La₂O₃ y CeO₂ en las propiedades fisicoquímicas del catalizador Ni/γ-AL₂O₃ para la producción de hidrógeno en el reformado de etanol en fase vapor. Se ...
Desenvolvimento de aluminas-y mesoporosas dopada com céria ezircônia pelo processo sol-gel para aplicações em catalisadoresautomotivos
(Universidade Federal de Minas GeraisUFMG, 2016-03-28)
The burning of hydrocarbons in vehicle engines produces a complex mixture of pollutants gases that need to be converted to less harmful products. Currently the way most used to make this conversion is through a vehicular ...
Multiple-wall carbon nanotubes obtained with mesoporous material decorated with ceria-zirconia
(Elsevier Science, 2021-01-15)
In this work, Ceria-Zirconia on ordered Santa Barbara mesoporous silica (Ce-Zr-SBA-15), has been used directly as a catalyst for the synthesis of carbon nanotubes (CNTs) through Chemical Vapor Deposition (CVD). In addition ...
Synthesis and characterization of mesoporous NiO2/ZrO2-CeO2 catalysts for total methane conversion
(Elsevier, 2017-07)
This work reports the synthesis and characterization of mesoporous NiO/ZrO2-CeO2 composites. These materials are still being developed due to their excellent morphological and structural properties, especially for solid ...
