“…Coatings 2024, 14, x FOR PEER REVIEW 5 of 15 Based on the thermodynamically stable phase diagram for the PO4 3− -and Ca 2+ -containing solutions [44], the elements of Ca, P and O in the surface coating are mainly present in the highly stable Ca3(PO4)2 and CaHPO4•2H2O. Their formation ensures that the formed coating films have good corrosion protectability for the substrate [8,43].…”

In this work, the morphology, anti-corrosion performance and degradation mechanisms of two phosphate chemical conversion coatings containing the AEO (fatty alcohol polyoxyethylene ether) and AES (fatty alcohol polyoxyethylene ether sodium sulfate) on an as-cast Mg-8wt.%Li alloy were explored and compared. Although two coating layers had a petal-shaped structure and were composed of leaf-shaped particles, the coating layer of the AES-coated sample was relatively dense due to the smaller size of the formed petal-shaped structure. Based on the electrochemical data and hydrogen evolution measurements, the corrosion protectability of the coating layer on the AES-coated sample was better than that on the AEO-coated sample. The determined corrosion current densities (icorr) of the AES-coated and AEO-coated samples in the 3.5 wt.% NaCl solution were, respectively, 7.8 mA·cm−2 and 11.7 mA·cm−2, whereas the icorr value of the coated sample without a surfactant was 36.2 mA·cm−2.

“…18 In particular, MCM-41 as mesoporous material has been widely applied for cationic dyes adsorption in environmental wastewater, and is a promising adsorbent for the purification of organic contaminants. [19][20][21][22][23] Improving MCM-41 adsorption capacity and selectivity has attracted significant attention during the last decade. 24 In this context, the introduction of heteroatom or metal oxide into the MCM-41 structure was suggested, which is considered as one of the most effective approaches to enhance its sorption affinity to dye.…”

The present study aimed to evaluate the potential of mesoporous silica MCM-41 and Al-MCM-41 (molar ratio Si/Al = 20) for the removal of Rhodamine 6G (Rh6G) from aqueous solution. The adsorbents were characterised by XRD, FTIR, SEM-EDX, BET, and UV-Raman. Obtained results related to XRD analysis indicated that the MCM-41 structure remained intact after the incorporation of Al species. Kinetic adsorption study showed that the higher removal (88.75 %, 26.62 mg g −1 ) of Rh6G dye was achieved by Al-MCM-41 at 60 min. FTIR analysis showed that hydrogen bonding played the dominant role in the Rh6G removal mechanism, while the pH results showed that electrostatic interaction was also a key factor. This study shows that the prepared mesoporous materials are inexpensive and efficient adsorbents for the removal of cationic dyes.
