“…The electrosynthesized NiFe-LDH NSAs also gives significantly long-term stability and the current density of OER remains constant at each given potential after 50 h of continued measurement. In addition, the electrosynthesis method can be extended to the various micro-substrates, which gives uniform core-shell nanostructures and improved electrochemical properties [132][133][134][135][136].…”

Electrochemical water splitting has great potential in the storage of intermittent energy from the sun, wind, or other renewable sources for sustainable clean energy applications. However, the anodic oxygen evolution reaction (OER) usually determines the efficiency of practical water electrolysis due to its sluggish four-electron process. Layered double hydroxides (LDHs) have attracted increasing attention as one of the ideal and promising electrocatalysts for water oxidation due to their excellent activity, high stability in basic conditions, as well as their earth-abundant compositions. In this review, we discuss the recent progress on LDH-based OER electrocatalysts in terms of active sites, host-guest engineering, and catalytic performances. Moreover, further developments and challenges in developing promising electrocatalysts based on LDHs are discussed from the viewpoint of molecular design and engineering.

Sustainable energy supply from renewable sources requires highly efficient and economically competitive energy-storage technologies. With flexible design, high energy-storage efficiency, and long-term cyclability, redox flow batteries are superior candidates for peak shaving and load leveling for smart grids in the energy generation, storage and distribution networks. With natural abundance, structural diversity and tunability, redox-active organic species as valuable alternatives to the traditional inorganic-based materials are promising to tackle the resource and performance limitations. To design aqueous organic redox flow batteries toward energy-dense, high-rate performance and durability, in this Review, strategies to maximize the cell voltage, effective concentration of organic species, and operating current density are discussed. Besides the inherent nature of the organic molecules, suitable solvents and supporting ions can affect their solvation behavior and promote their chemical stability.[a] Dr.A patent concerning supporting electrolyte for organic materials has been filed by KIST Europe and CMBlu Projekt AG (PCT/ EP2018/056087) that names R.C. as an inventor.

“…A silicate core/silver shell nanocomposite material was obtained by reduction of insoluble AgCl in water in the presence of SiO 2 -NHR silicate nanoparticles. 38 The efficiency of the mediated electrosynthesis method was also shown in the preparation of cobalt nanoparticles in aprotic DMF by potentiostatic electrolysis in an undivided cell at controlled potentials of anthracene reduction (mediator) to an radical anion at room temperature using a Co anode as an in situ Co(II) source. 39 In this paper, we demonstrate for the rst time the capabilities of mediated electrosynthesis for the preparation of gold nanoparticles in an aqueous medium.…”
