Palladium nanoparticles with varying particle diameter (6.9–25.1 nm) have been synthesized by single-pot wet chemical technique in presence of poly vinyl alcohol by controlling the duration of reflux. The resulting nanoparticles have been dip-coated on Ni-foil, followed by determination of kinetic parameters of the anode-catalysts in reference to alkaline oxidation of methanol (AOM) by electrochemical and IR-spectroscopic techniques. The morphology and surface characteristics of the Pd nano-catalyst have been investigated by electron microscopy in conjugation with energy dispersion spectroscopy. The results show the formation of formate and carbonate with no change in selectivity but improved kinetic parameters on decreasing the diameter of constituting Pd nanoparticles. The studies of cyclic voltammetry of methanol, formaldehyde and formate reveal that the electrode constituted with Pd nanoparticles having average diameter of 6.9 nm obtained by applying the lowest time (0.33 h) of reflux, is the best for all the fuels. The studies also help understanding the stability of the electrodes, proposition of the intermediates and plausible mechanism of the reaction. 相似文献

It is puzzling today to explain diversity and imperfection of actual transmission monopoly designs in competitive electricity markets. We argue that transmission monopoly in competitive electricity markets has to be analyzed within a [Wilson, R, 2002. Architecture of the power markets. Econometrica 70(4), 1299–1344] modular framework. Applied to the management of electricity flows, at least three modules make the core of transmission design: (1) the short run management of network externalities; (2) the long run management of network investment; and (3) the coordination of neighboring transmission system operators (TSOs) for cross-border trade. In order to tackle this diversity of designs of TSOs, we show that for each of these modules, three different basic ways of managing them are possible. Among the identified 27 options of organization, we define an ideal TSO. Second, we demonstrate that (1) monopoly design differs from this ideal TSO and cannot handle these three modules irrespective of the “institutional” definition and allocation of property rights on transmission, while (2) definition and allocation of property rights on transmission cannot ignore the existing electrical industry and transmission network structure: they have to complement each other to be efficient. Some conclusions for regulatory issues of TSOs are derived from this analysis of network monopoly organization. 相似文献
