Summary: The electrodeposition of beta-PbO2 into vertically arranged black titanium oxide nanoarrays (BTN) to prepare an electrode (Ti/BTN/beta-PbO2) for advanced oxidation treatment was investigated. The study found that Ti/BTN/beta-PbO2(5 s) showed the greatest photoelectrocatalysis, while Ti/BTN/beta-PbO2(30 min) demonstrated the best ability to degrade pollutants due to the presence of colloidal PbO(OH)2 generating electroreactive species. Additionally, the activity and stability of Ti/BTN/beta-PbO2 were attributed to the vertical electrons transfer channel provided by BTN and the interlocked structures formed between BTN and beta-PbO2.

Summary: In this study, a highly conductive MXene (Ti3C2Tx) was fabricated for the first time using electrophoretic deposition (EPD) as an interlayer to prepare a novel PbO2 electrode. The Ti3C2Tx interlayer significantly improved the electrochemical performance of the EPD-2.0/PbO2 electrode, reducing the charge transfer resistance, increasing the number of active sites, and enhancing the generation ability of ·OH radicals. Experimental results showed that the EPD-2.0/PbO2 electrode exhibited promising potential for the electrochemical degradation of basic fuchsin (BF).

Summary: This study explores the potential use of duty cycle variation to improve the mechanical and surface roughness properties of Ni-Al2O3 nanocoatings through pulse electrodeposition. The nanocomposite coatings with varying duty cycles ranging from 20% to 100% were analyzed using bearing area curves and power spectral densities to assess their areal and surface roughness properties. The results demonstrate that a decrease in duty cycle leads to an enhancement in both aerial and surface roughness properties, attributed to variations in grain size caused by different time intervals during pulse coatings. The increase in grain size with changing duty cycle was confirmed with scanning electron microscopy. Furthermore, an increase in grain size with an increase in duty cycle resulted in a decrease in nanohardness. This research provides a novel method for obtaining Ni-Al2O3 nanocomposite coatings with improved surface roughness and hardness properties for wider industrial applications.
