Tungsten based electrocatalysts as non-noble alternatives to common platinum based fuel cell catalysts
No full textToday fuel cells are far from being common place in the commercial market, primarily due to their high cost. The cost of such a system is largely determined by the platinum based catalysts used at both the anode and cathode of the fuel cell. If a non-noble fuel cell electrocatalyst could be used at either of these electrodes, the cost of a fuel cell system would be drastically reduced. Highthroughput physical vapour deposition and the modification of single crystal surfaces, has been used to synthesise candidate non-noble electrocatalysts which were then screened to determine their activity.Amorphous tungsten carbide thin films were shown to be catalytically active towards both the hydrogen evolution reaction (HER) and the hydrogen oxidation reaction (HOR). The constituent elements were seen to be less active than the alloys. These results are consistent with the literature where it has also been seen that WC is active, with W2C showing poorer activity.1,2 The trend in current density with respect to alloy composition confirms the results in the literature, with the highest activity seen at compositions corresponding to the WC phase, and a local minima in activity seen at compositions correspondingto the W2C phase.Metastable and amorphous intertransition metal alloys of WCu are shown to catalyse both the HER and the HOR. The constituent metals again exhibit poor activity. The results are consistent with ab initio calculations predicting HER activity for Cu overlayers on W, with the detected changes of the density of states (DOS) at the Fermi level associated with alloy formation.3 Two maxima in the HER activity are observed as a function of composition. This activity is associated with a metastable phase at W20Cu80 and a second at W50Cu50. The alloy at 50 at% also shows a maximum in the HOR activity, whereas the phase at W20Cu80 is not HOR active. The W20Cu80 phase is found to beoxygen covered at the HOR potential, explaining its inactivity. These results highlight the potentials of developing non-noble metal alloy catalysts for hydrogen fuel cells

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
