Composite electrodes made of Pt nanoparticles deposited on carbon nanotubes grown on fuel cell backings

Carbon Nanotubes Supported Metal Nanoparticles for the Applications in Proton Exchange Membrane Fuel Cells (PEMFCs)

“…Several recent reports show that CNTs can be chemically functionalized by silane coupling agents (Kamavarama et al, 2009;Ma et al, 2006;X. Sun et al, 2003;Villers et al, 2006).…”

“…The deposition of the Pt NPs was carried out by immersing the CNTs in a solution containing PtCl 2 , a silane derivative and water in ethanol (X. Sun et al, 2003), which produced a Pt 2+ adsorbed CNTs. The CNT supported Pt NPs were formed in a flow of H 2 and Ar.…”

Pt and Pt‐Ru Nanoparticles Dispersed on Ethylenediamine Grafted Carbon Nanotubes as New Electrocatalysts: Preparation and Electrocatalytic Properties for Ethanol Electrooxidation

“…35 In order to improve the performance of CNT as catalyst support, the surfaces of CNT have been functionalized with functional groups like carboxyl, 25,[36][37] amino, 38,39 hydrosulfuryl 40 and sulfonyl 41 groups or polymers 42 having a good affinity with precious metals, using various organic synthesis routes, chemical adsorptive methods or electrochemical methods.…”

New Materials in Electochemical Sensors for Pesticides Monitoring

“…The latter involves the generation of small nuclei to further promote metal deposits on carbon nanotubes (Ang et al, 2000;Liu et al, 2002). In this sense, Sun et al (2003) show that it is possible to obtain very small Pt particles deposited onto multiwalled carbon nanotubes (MWCNTs) and that these metal particles are in electrical contact, through the MWCNT, with the carbon backing, enabling the composite structure to be used as an electrode. Also the atom transfer radical polymerization (ATRP) is a very powerful technique in functional macromolecular design and new material preparation, which has been applied successfully to the controlled functionalization of carbon nanotubes.…”
