Special Issue Information

Dear Colleagues,

Electro-catalysis lies at the core of energy storage and conversion devices and electrode design is a key-enabler of these technologies. An electrode is a multi-components system where specific physicochemical properties such as redox and acid/base properties, hydrophobic/hydrophilic characteristics, surface area and electrical conductivity operate concertedly to enable a reaction to occur efficiently. Not only the nature, nuclearity and morphology of the active phase, but also other factors significantly modify the performances of the electrode. Amongst others, support effects, promoters and more recently ligands effects in single metal atom/organic hybrid systems have been investigated for fine-tuning of the activity and selectivity. Additionally, the “electrode prehistory”, in terms of the synthetic methods and the materials used for the electrode preparation, has also a significant influence on performances.

This Special Issue aims to cover recent trends and progresses in the development of electrocatalysts for electro-catalytic applications including, but not limited to, the carbon dioxide reduction, hydrogen evolution reaction, oxygen reduction and evolution reactions and ammonia synthesis. The goal of this issue is to provide the readership with a collection of articles in which emphasis is placed not only on the discovery of new active materials and/or electrode preparation but also on the understanding of the nanostructural and chemical characteristic of the electrodes responsible for improved performance.

Nickel electrodes under continuous potential cycling were applied for the electrooxidation of benzyl alcohol and glycine in KOH solutions, and their activities were measured and compared by cyclic voltammetry. It is shown that intrinsic activities of both reactions decrease with the increasing catalyst loadings, and a more significant decreasing trend was observed in glycine electrooxidation when compared to benzyl alcohol electrooxidation. These phenomena may be explained by an increasing of mass loading induced a decrease of the catalyst surface conductivity, structure changes of Ni(OH)2 from α-phase to β-phase, and the intercalation of glycine molecules into nickel hydroxide interlayers.

Title: Plasma Deposited Ru-based Thin Films for Photoelectrochemical Water Splitting

Author: Jacek Tyczkowski 

Abstract: Plasma-enhanced metalorganic chemical vapor deposition (PEMOCVD) was employed to produce a ruthenium-based thin films. The surface chemical composition was examined by X-ray photoelectron spectroscopy (XPS). To determine the electrochemical and photoelectrochemical properties of the films, the linear sweep voltammetry (LSV) at pH = 13.6 was applied. XPS results indicated that Ru in the as-deposited films was mainly in metalic state (Ru0) whereas after the electrochemical treatment, the higher oxidation states were formed (mainly Ru4+). This RuOX catalyst exhibits high photoelectroactivity in the oxidation of water – the onset potential is approx. 1.37 V (vs. RHE) and the photocurrent density of 9.0 mA/cm2 is reached at 1.63 V (vs. RHE). The plasma deposited RuOX catalyst seems to be an interesting candidate for the photoanode material for photoelectrochemical water splitting.
