Today, with the threatening energy crisis and global warming, electrochemistry faces a great challenge as a discipline interfacing chemistry and electrical engineering. The efficient conversion and storage of energy are closely correlated to the development of electrochemical energy technologies, such as fuel cells, batteries and electrolyzers. Such devices are claimed to dominate the power supply market in a future sustainable energy economy. The practical efficiencies must be yet boosted before many of the aforementioned technologies become viable for large-scale use. In particular, more active, stable, and economically viable catalysts must be developed for the electrocatalytic processes occurring at practical electrodes of the cells. In this context, the research and development of efficient catalysts are key points to reach this target. This Special Issue is intended to present and discuss the most recent advances and developments in heterogeneous catalysis for application in electrochemical energy conversion and storage devices.

Abstract: Alloys of platinum and lanthanides present a remarkable activity for the oxygen reduction reaction, both in the form of extended surfaces and nanoparticulate catalysts. Co-sputter deposited thin film catalysts based on platinum and gadolinium show great oxygen reduction activity improvement over pure Pt. The sputter deposition technique represents a viable and versatile approach for investigating model catalyst systems with different compositions. In this work, co-sputtered Pt5Gd and Pt7.5Gd thin films were investigated using X-ray absorption spectroscopy as well as standardised electrochemical techniques. These investigations revealed the importance of forming alloys with specific stoichiometry, supporting the need of forming compressively strained Pt overlayers in order to achieve optimum catalytic performances.

Title: Electrocatalysis for Oxygen Reduction Reaction on EDTAFeNa and Melamine co-Derived self-Supported Fe-N-C Materials

Abstract: Self-supported Fe-N-C materials were prepared by carbonization of dual precursors including EDTA ferric sodium (EDTAFeNa) and melamine (MA) followed by acid-leaching and final pyrolysis. Towards oxygen reduction reaction (ORR) in 0.1 M KOH, the as-prepared MA/EDTAFeNa-AL-HT2 delivered onset (Eonset) and half-wave (E1/2) potentials of 0.97 and 0.84 V vs RHE, respectively, identical with that of a state-of-the-art Pt/C catalyst, accompanied with predominantly 4-electron pathway. The introduction of MA and extension of acid-leaching promoted a positive shift of E1/2 for 50 mV relative to that for only EDTAFeNa-derived counterpart. It is revealed that the enhancement of ORR activity is attributed to increase of nitrogen content and decrease of magnetic Fe species whilst nearly excluding effects of the graphitization degree, configuration of iron species and mesoscopic structure.
