The role of partially fluorinated carbon (CFx) supported platinum nanoparticles as proton exchange membrane fuel cell (PEMFC) electrodes in a hydrogen is investigated. CFx employed catalyst support via impregnation for oxygen reduction reaction (ORR) at various loadings to determine the optimal loading ORR and compared widely used (non-fluorinated) Vulcan Carbon (XC-72R). In half-cell testing, ...

PtRu nanoparticles decorated on carbon-based supports are of great interest for direct methanol fuel cells (DMFCs). In this study, alloy carbon Vulcan XC-72 (C), multi-walled nanotubes (MWCNTs), and C-MWCNTs composite were synthesized by co-reduction method. As a result, obtained small mean size (dmean = 1.8–3.8 nm) with distribution 1–7 nm. We found that PtRu/C60MWCNTs40 possesses not only hig...

The use of alternative fuels can improve the performance diesel engine in terms pollution, [1], [2], [3].Low-carbon [2] successfully replace conventional modern engines or future [1]. This may be an efficient method to ameliorate exhaust emissions for 2050, especially CO 2 reduction, important issue at internal combustion automotive fleets. liquid petroleum gas, [1-5] which has a low carbon con...

T164, A0969, page 1442, journal of the American Society of Nephrology, September 1996, Volume 7, #9 Link not available Abstract: We performed a cross-sectional study of BIA (Bioelectrical impedance analysis, BIA 101-Q, RJL Systems, Clinton Township, MI) in 3009 HD (hemodialysis) patients with follow-up to 12 (median 8) months to evaluate the relation between impedance and survival. 296 deaths w...

Vulcan XC-72 samples were functionalized with methanol (MeOH) by Intermittent Microwave Heating (IMH) under different treatment conditions. To assess the effectiveness of proposed method citric acid functionalization was also performed as comparison. The obtained carbonaceous supports used to synthesize Pt/C-MeOH and Pt/C-CA nanocatalysts. surface assessed using them support for Pt/C nanocataly...

This study investigates the use of DC sputtering, physical vapor deposition as a facile method for creating ultralow loading, Au/C electrodes in detection As (III) water. The sputtered nanofilm on carbon papers, substantially reduces amount Au consumed per electrode, <10 μg cm−2, compared to wire, foil, or screen-printed electrodes. Linear stripping voltammetry (LSV) was chosen analytical simpl...

Understanding and improving durability of fuel cell catalysts are currently one of the major goals in fuel cell research. Here, we present a comparative stability study of multi walled carbon nanotube (MWCNT) and conventional carbon supported platinum nanoparticle electrocatalysts for the oxygen reduction reaction (ORR). The aim of this study was to obtain insight into the mechanisms controllin...
