This study presents a facile and rapid method for synthesizing novel Layered Double Hydroxide (LDH) nanoflakes, exploring their application as photocatalyst, investigating the influence of condensed phosphates' geometric linearity on photocatalytic properties. Herein, MgO film, obtained by plasma electrolysis AZ31 Mg alloys, was modified growing an LDH which further functionalized using cyclic sodium hexametaphosphate (CP) linear tripolyphosphate (LP). CP acted enhancer flake spacing within structure, while LP changed dispersion orientation. Consequently, CP@LDH demonstrated exceptional efficiency in heterogeneous photocatalysis, effectively degrading organic dyes like Methylene blue (MB), Congo red (CR), Methyl orange (MO). The unique structure likely enhances surface reactions improves catalyst's interaction with dye molecules. Furthermore, phosphate contributes to higher area reactivity CP@LDH, leading its superior performance compared LP@LDH. Specifically, LP@LDH notable degradation efficiencies 93.02 %, 92.89 88.81 % MB, MO, CR respectively, over 40 min duration. highest were observed case sample, reporting 99.99 98.88 CR, 99.70 MO. underscores potential highly effective photocatalyst degradation, offering promising prospects environmental remediation water detoxification applications.

Impressive strides in amelioration of corrosion behavior of Mg-based alloys through the PEO process combined with surface laser process: A review

Journal of Magnesium and Alloys, Journal Year: 2023, Volume and Issue: 11(12), P. 4390 - 4406

Published: Dec. 1, 2023

The unsatisfactory corrosion properties of Mg-based alloys pose a significant obstacle to their widespread application. Plasma electrolytic oxidation (PEO) is prevalent and effective coating method that produces ceramic-like oxide on the surface alloys, enhancing resistance corrosion. Research has demonstrated PEO treatment can substantially improve performance based magnesium in short term. In an effort enhance coatings over extended period time, researchers have turned attention use laser processes as both pre- post-treatments conjunction with process. Various processes, such shock melting (LSM), adhesion (LSA), texturing (LST), peening (LSP), been investigated for potential Mg substrates alloys. These homogenize alter microstructure while leaving bulk material unchanged, thereby modifying substrate surface. However, porous rough structure coatings, open interconnected pore structure, reduce long-term resistance. As such, various are well-suited modification these coatings. This study will first examine process types used this process, before investigating behavior post-treatment processes.
