Platinum surface modification with cerium species and the effect against the methanol anodic reaction
(Elsevier B.V. Sa, 2008-06-15)
Spontaneous deposition and electrochemical deposition by potential perturbation programs were used to place cerium-containing species on platinum surfaces in acid solution. Cyclic voltammetric profiles of cerium-modified ...
Platinum supported on mesoporous carbon as cathode catalyst for direct methanol fuel cells
(Elsevier Science, 2015-03)
Platinum nanoparticles supported on mesoporous carbon were obtained by an impregnation and reduction method with NaBH4 as the reducing agent. The high specific surface area mesoporous carbon was obtained by carbonization ...
Self-assembled films from chitosan and poly(vinyl sulfonic acid) on Nafion® for direct methanol fuel cell
(Sociedade Brasileira de Química, 2012)
Chitosan/poly(vinyl sulfonic acid) (PVS) films have been prepared on Nafion® membranes by the layer-by-layer (LbL) method for use in direct methanol fuel cell (DMFC). Computational methods and Fourier transform infrared ...
Methanol/air fuel cells: catalytic aspects and experimental diagnostics
(Pergamon-Elsevier Science Ltd, 2008-07)
Methanol/air fuel cell with direct feed of methanol has received growing attention due to the possibility of using a liquid fuel of simple storing. This work comments studies on the preparation of PtRu catalysts for methanol ...
