Summary: Researchers propose a simple method for the preparation of nanoporous gold films, which can be achieved by high voltage electrolysis or anodic contact glow discharge electrolysis. The structural properties of the resulting films can be controlled by adjusting the electrolysis conditions and the reduction reaction conditions.

Summary: Pt is found to be stable during electrolysis and CGDE, while Au and Cu exhibit voltage-dependent oxide formation. Keeping the electrodes in the electrolysis solution after electrolysis leads to reduction of oxides, which then form a porous film. These reduced oxides represent a possible new class of materials in energy storage and conversion studies.

Summary: Nanoporous Au (NPG) has unique properties compared to bulk Au and holds promise for various applications. Understanding the structure formation is essential for tailoring NPG films' properties, such as porosity and thickness, for specific applications. In this study, NPG was prepared by electrochemical reduction of Au oxide formed during high voltage electrolysis on poly-oriented Au single crystal (Au POSC) electrodes. The crystallographic orientation of the substrate affected the macroscopic structure of the NPG films, while the formation of Au oxide was mostly independent of crystallographic orientation.

Summary: This study investigates the impact of small temperature drops on Contact Glow Discharge Electrolysis (CGDE). The addition of frozen KOH solution significantly increases the current, while boiling KOH solution has no effect. Similar results are observed with type III deionized water. These findings highlight the importance of electrolyte temperature control for CGDE systems.

Summary: Penicillium expansum spores in apple juice were effectively inactivated by contact glow discharge electrolysis (CGDE). The mechanism of spore inactivation was found to involve the destruction of cell membrane integrity and the generation of reactive oxygen species accumulation. CGDE has potential industrial relevance for treating fungal spore-contaminated liquids in the food industry.

Summary: This paper reviews the progress of using plasma-driven solution electrolysis (PDSE) for hydrogen production and discusses the effects of various parameters on energy efficiency, energy yield, and hydrogen production rate. The results show that in the cathodic regime of PDSE, the hydrogen production rate and energy efficiency are significantly higher compared to the anodic regime.

Summary: The results of an experimental study on hydrogen production at a tungsten discharge electrode with negative polarity in the DC electrolysis of a typical 10 wt% Na2CO3 aqueous solution in three operational regimes (the Faradaic, transition, and plasma-driven solution electrolysis (PDSE)) are presented. The highest hydrogen production rate was achieved in the cathodic PDSE regime at the applied DC voltage of 198 V. However, the energy yield of hydrogen production in the PDSE regime was lower than that in the Faradaic regime. The energy balance analysis showed that most of the electrical energy consumed in the cathodic PDSE regime was spent on heating and evaporation of the electrolytic solution.

Summary: Nanoscale flower-like β-Ni(OH)2 microsphere is a promising electrode material for supercapacitors due to its low cost, long cycle life, and high theoretical capacitance. However, its preparation often involves high temperatures or the use of complicated alkaline system, water-soluble precursors, and surfactants. In this study, a 3D flower-like β-Ni(OH)2 microsphere was successfully fabricated using cathode glow discharge electrolysis (CGDE) plasma. The microsphere exhibited excellent electrochemical performance and morphology characteristics.
