Tuning zirconia-supported metal catalysts for selective one-step hydrogenation of levoglucosenone
(Royal Society of Chemistry, 2019-07)
Levoglucosenone, directly produced from cellulose-containing residual biomass via pyrolysis treatments, is believed to be a promising bio-renewable platform for both fine and commodity chemicals. In this work, the possibilities ...
Catalisadores de Au suportados aplicados à oxidação preferencial do CO : influência da interação entre Au e Fe nos sítios ativos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2017-04-07)
New sources of clean energy have been studied, such as hydrogen (H2). Carbon monoxide, a subproduct of its production, poisons the fuel cell. To reach concentrations below 10 ppm, the addition of preferential CO oxidation ...
Funcionalização em sítios distintos da molécula do óxido de limoneno: processos “one-pot” de hidroformilação/isomerização e de hidroformilação/acetilação
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE QUÍMICAPrograma de Pós-Graduação em QuímicaUFMG, 2021-03-26)
Using rhodium-based catalytic systems, one-pot processes of hydroformylation/
isomerization and hydroformylation/acetylation of limonene oxide were developed, in order to produce value-added products via the functionalization ...

Cyclohexene and cycloodene epoxidation with aqueous hydrogen peroxide using transition metal-free sol-gel alumina as catalyst
(Wiley-v C H Verlag GmbhWeinheimAlemanha, 2004)
Mixed oxides tuned with alkaline metals to improve glycerolysis for sustainable biodiesel production
(Elsevier Science, 2017-01)
In this study, monoglycerides were produced as glycerol value-added products via transesterification reaction of methyl stearate. This green and selective process involved catalysis from hydrotalcite-like compounds with ...
Obtención de metanol a partir de la oxidación selectiva de metano empleando materiales catalíticos de hierro y molibdeno soportados en óxido de silicio
(Bogotá - Ingeniería - Doctorado en Ingeniería - Ciencia y Tecnología de MaterialesUniversidad Nacional de Colombia - Sede Bogotá, 2020-07-10)
Antes de iniciar, es el momento de compartir que como suele ocurrir en la investigación científica, usualmente se inicia con una idea puntual y definida y durante la marcha está cambia un poco de rumbo. Así, a pesar de que ...
Nanoestructured catalysts for organic reactions: design, synthesis and applications
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-07-29)
The development of more efficient and selective catalysts actively contributes for the design of safer, cleaner and less energy-demanding processes, and, therefore, catalysis is one of the cornerstones of green chemistry. ...
Iron-alumina materials prepared by the non-hydrolytic sol–gel route: Synthesis, characterization and application in hydrocarbons oxidation using hydrogen peroxide as oxidant
(2010)
Novel alumina materials containing FeIII ions were prepared by the non-hydrolytic sol–gel route and applied as heterogeneous catalysts in the oxidation of hydrocarbons (cyclooctene and cyclohexane) by the green oxidant ...
