“…Most transition metal-based catalysts used for water electrolysis are prepared on binder solid electrode support, which reduces the activity and durability of the catalyst system. In this regard, catalysts derived from a self-loaded metal–organic framework (MOF) have been introduced with a good conductivity, a high electrocatalytic surface area, enhanced mechanical stability, and strong catalyst–support interactions [ 91 , 92 , 93 , 94 , 95 , 96 ]. MOFs are porous crystalline materials in which the metal centers are connected by coordination bonds via organic bridging ligands to synthesize core–shell and hollow structures.…”

Developing earth-abundant and highly effective electrocatalysts for electrocatalytic water splitting is a prerequisite for the upcoming hydrogen energy society. Recently, manganese-based materials have been one of the most promising candidates to replace noble metal catalysts due to their natural abundance, low cost, adjustable electronic properties, and excellent chemical stability. Although some achievements have been made in the past decades, their performance is still far lower than that of Pt. Therefore, further research is needed to improve the performance of manganese-based catalytic materials. In this review, we summarize the research progress on the application of manganese-based materials as catalysts for electrolytic water splitting. We first introduce the mechanism of electrocatalytic water decomposition using a manganese-based electrocatalyst. We then thoroughly discuss the optimization strategy used to enhance the catalytic activity of manganese-based electrocatalysts, including doping and defect engineering, interface engineering, and phase engineering. Finally, we present several future design opportunities for highly efficient manganese-based electrocatalysts.

“…The substrate is to be subjected to a proper cleaning/pretreatment procedure in order to provide good adhesion of the deposit [37,38,49,95]. These procedures include both chemical (dissolution of surface contaminants; etching) as well as mechanical (fine sanding) treatment [31,32,34,37,38,49,95,209]. In contrast to the substrates made with noble metals, less noble materials, such as Cu, may require removal of native surface oxides/hydroxides.…”

“…Cu [29,149,209]. The Ni layer remaining after the dissolution of such substrate acts as the target, providing that its thickness and mechanical stability are sufficiently high [29,149,209]. This approach, however, has not been applied in production of medical isotopes.…”

“…Further on, at too high current densities, the morphology of the deposit deteriorates [39,55,91,95,158,209] and a high internal stress is developed [76,184,221]. Poor-quality deposits are obtained also when the current density is too low indicating that the applied current density should vary in a limited range [95].…”

This paper reviews reported methods of the electrochemical deposition of nickel layers which are used as target materials for accelerator production of medical radioisotopes. The review focuses on the electrodeposition carried out from aqueous electrolytes. It describes the main challenges related to the preparation of suitable Ni target layers, such as work with limited amounts of expensive isotopically enriched nickel; electrodeposition of sufficiently thick, smooth and free of cracks layers; and recovery of unreacted Ni isotopes from the irradiated targets and from used electrolytic baths.

The present work proposes a method for fabricating metallic Al particles in aqueous solution. An aqueous colloidal solution was prepared from an aqueous aluminum nitrate nonahydrate solution by electrolysis using metallic Al plates as the anode and cathode under ultrasonic irradiation in water at 25–45 °C. The sizes of the particles in the colloidal solutions prepared at 25, 35, and 45 °C were 76.3, 77.0, and 84.7 nm, respectively. The powder obtained from the colloidal solution prepared at 25 °C was not crystalline. By contrast, the powders obtained from the colloidal solutions prepared at 35 and 45 °C had a crystal structure of cubic Al and crystal sizes of 55.7 and 59.3 nm, respectively. Thus, elevated temperatures promoted both particle growth and crystal growth, which was explained by higher temperatures increasing the frequency and energy of particle collisions. The metallic Al particles were chemically stable in both an aqueous solution and the ambient atmosphere. The chemically stable metallic Al particles are expected to be used as sources for fabricating materials related to fuels, energy storage, and pigments.
