High activated carbon loading mixed matrix membranes for gas separations
(Springer, 2012-04)
Mixed matrix membranes (MMMs) containing highest amounts of activated carbon (AC) reported to date were prepared for gas separation. A polymeric phase of semicrystalline polyvinyl chloride (PVC) was loaded with different ...
Preparação de catalisadores baseados em carvão ativado polimérico para a desidrogenação do etilbenzeno com dióxido de carbon
(Instituto de QuímicaPrograma de Pós Graduação em QuímicaIQbrasil, 2016-09-10)
Resinas de estireno e divinilbenzeno são materiais atrativos para muitos propósitos
por causa das suas propriedades, variedade de grupos funcionais na superfície e

(Springer Nature Switzerland AG, 2019)
Synthesis of ω-amino-α-phenylcarbonate alkanes and their polymerization to [n]-polyurethanes
(John Wiley & Sons Ltd, 2010-09)
Aliphatic [n]-polyurethanes have recently been synthesized from ω-isocyanato-α-alkanols or, more traditionally, by cationic ring-opening polymerization of cyclourethanes or by the Bu2Sn(OMe)2-promoted polycondensation of ...
Effect of Nitrogen-Functional Groups on the ORR Activity of Activated Carbon Fiber-Polypyrrole-Based Electrodes
(Springer, 2018-07-10)
Polypyrrole (PPy) coatings inside the microporosity of an activated carbon fiber (ACF) were synthesized by chemical polymerization obtaining ACF-PPy composites. N-doped ACFs were prepared by carbonization of the ACF-PPy ...
Electrochemical Properties of the Oxo-Manganese-Phenanthroline Complex Immobilized on Ion-Exchange Polymeric Film and Its Application as Biomimetic Sensor for Sulfite Ions
(Wiley-Blackwell, 2014-10-01)
A biomimetic sensor containing the oxo-bridged dinuclear manganese-phenanthroline complex incorporated into a cation-exchange polymeric film deposited onto glassy carbon electrode for detection of sulfite was studied. ...
Preparation and characterization of composite polyaniline materials for catalytic purposes
(Academic Press Inc Elsevier Science, 2008-09-15)
Composite film electrodes were prepared by open-circuit Pt deposition on polymeric PANI films that were electrosynthesized from aniline acid solutions with suspended carbon particles (CPs). Gold, nickel and Ni-based alloy, ...
Selectivity of the cyclic carbonate formation by fixation of carbon dioxide into epoxides catalyzed by Lewis bases
(Pergamon-Elsevier B.V. Ltd, 2014)
Electrochemical conversion of carbon dioxide into CHO- containing compounds on multimetallic porphyrins
(Wiley, 2017)
This work describes the electrochemical reduction of carbon dioxide in aqueous solution mediated by tetraruthenated metal-loporphyrins (TRP; Co(II) and Zn(II)) in Nafion (Nf) and polyvinyl chloride (PVC) as a support. The ...
Development of Plurimetallic Electrocatalysts Prepared by Decomposition of Polymeric Precursors for EtOH/O-2 Fuel Cell
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
This work aimed to develop plurimetallic electrocatalysts composed of Pt, Ru, Ni, and Sn supported on C by decomposition of polymeric precursors (DPP), at a constant metal: carbon ratio of 40:60 wt.%, for application in ...
