Investigation of the CO tolerance mechanism at several Pt-based bimetallic anode electrocatalysts in a PEM fuel cell
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The electrocatalysis of CO tolerance of Pt/C, PtRu/C, PtFe/C, PtMo/C, and PtW/C at a PEM fuel cell anode has been investigated using single cell polarization and online electrochemical mass spectrometry (EMS) measurements, ...
Reducción catalítica selectiva de NOx sobre catalizadores Rh/TiO₂
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2015)
La eliminación de NOx de los gases de escape del motor es un aspecto ambiental muy importante debido a su impacto perjudicial sobre el medio ambiente y porque provoca que la salud de los habitantes de las grandes ciudades ...
Conversion of Biomass-Derived 2-Hexanol to Liquid Transportation Fuels: Study of the Reaction Mechanism on Cu–Mg–Al Mixed Oxides
(Springer/plenum Publishers, 2015-07)
The reaction mechanism of 2-hexanol conversion to high molecular weight compounds to be used as liquid transportation fuels was studied on MgO, Cu/SiO2 and a bifunctional Cu-Mg-Al mixed oxide with 8 wt. % Cu (catalyst ...
Desenvolvimento de catalisadores bifuncionais a base de fosfato e suas aplicações catalíticas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2022-02-17)
The development of bifunctional acid catalysts is an area of heterogeneous catalysis in intense growth, mainly due to the possibility of performing consecutive reactions using a single catalyst and a single reactor. In ...
