Methanol electro-oxidation on mesocarbon microbead supported Pt catalysts

Direct synthesis of graphitic carbon nanostructures from saccharides and their use as electrocatalytic supports

“…those reported for electrocatalysts supported on other forms of graphitic carbon, such as mesocarbon microbeads [22], onion-like fullerenes [23], single-wall carbon nanotubes [24] or multiwalled carbon nanotubes [25]. We recently achieved similar ESA values for catalysts made up of Pt nanoparticles deposited on GCNs obtained from pine sawdust [10] and Fe(II) and Co(II) gluconates [11].…”

Carbon monoxide and ethanol oxidation on PtSn supported catalysts: Effect of the nature of the carbon support and Pt:Sn composition

“…It is usually suggested that the use of carbon materials with an ordered structure and high electrical conductivity improves the fuel cell performance, and because of this, many research groups have recently made efforts to synthesize and use different novel carbon supports such as nanotubes [23][24][25][26][27], nanofibers [28,29], carbon microspheres [30,31], hard carbon spherules [32], carbon aerogels and xerogels [33,34], and mesoporous carbons for fuel cell applications [35]. In particular, carbon nanofibers (CNF) have been extensively studied as catalyst support for the electrooxidation of alcohols, mainly for their high resistance to corrosion [36][37][38] and their high electrical conductivity that make them good candidates to replace the commercial Vulcan XC-72R support.…”

A solid-polymer-electrolyte direct methanol fuel cell (DMFC) with Pt-Ru nanoparticles supported onto poly(3,4-ethylenedioxythiophene) and polystyrene sulphonic acid polymer composite as anode

“…For instance, it is found that carbons with lower concentration of acid-base groups 13 and carbons with sulfur-or nitrogen-based functionalities 15 ameliorate the catalytic activity. Consequently, considerable efforts have been expended on the optimization and development of new support material such as graphite nanofibres, 16 carbon nanotubes 17,18 and mesocarbon microbeads 19 in order to improve both the oxidation rate and electrode stability towards methanol electro-oxidation. These materials have high surface-area that facilitates uniform dispersion of catalyst and, since these are electronically more conductive than carbon, these have also attracted attention as alternate support materials for fuel cell catalysts.…”
