Evaluation of the activity of Pt–Ru electro catalysts based on LyFlex®Gas Diffusion Layer for the electro-oxidation of methanol
The gas diffusion layer (GDL) is vital to the performance and durability of direct methanol fuel cell (DMFC). The GDL plays an important role in water management, catalyst efficiency and conductivity of DMFC. The GDL consists of a carbon substrate that can either be woven or non-woven. The various substrates used to produce GDLs result in very different physical characteristics, particularly su...
متن کاملEffects of the Solvent and Calcination Temperature on LaFeO3 Catalysts for Methanol Oxidation
In this work, two types of solvents ethanol or water were used in preparation of the LaFeO3 catalysts by citrate sol gel method. The obtained samples were subjected to various calcination temperatures in order to study the catalytic activity and stability for methanol electro-oxidation by XRD, cyclic voltammetry and chronoamperometry. The crystallinity of the LaFeO3 ph...
متن کامل“the effect of risk aversion on the demand for life insurance: the case of iranian life insurance market”
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
15 صفحه اولCatalysts for the Selective Oxidation of Methanol
In industry, one of the main catalysts typically employed for the selective oxidation of methanol to formaldehyde is a multi-component oxide containing both bulk Fe2(MoO4)3 and excess MoO3. It is thought that the excess MoO3 primarily acts to replace any molybdenum lost through sublimation at elevated temperatures, therefore preventing the formation of an unselective Fe2O3 phase. With both oxid...
متن کاملMethanol Electro-Oxidation on Pt-Ru Alloy Nanoparticles Supported on Carbon Nanotubes
Carbon nanotubes (CNTs) have been investigated in recent years as a catalyst support for proton exchange membrane fuel cells. Improved catalyst activities were observed and attributed to metal-support interactions. We report a study on the kinetics of methanol electro-oxidation on CNT supported Pt-Ru alloy nanoparticles. Alloy catalysts with different compositions, Pt53Ru47/CNT, Pt69Ru31/CNT an...
