“…Transmission electron microscope (TEM) image (Figure 4d) shows the selfmade CeO 2 has a nanoscale size range of 20-50 nm, exhibiting an agglomeration phenomenon, which is mainly due to its high surface energy. [43,44] Figure 4e displays the SEM image of MCP that has a rough and polygon morphology covered uniformly by smaller nanoparticles, which is mainly composed of Ce, N, and Ti, as revealed by the energy dispersive X-ray spectroscopy (EDS) mapping. The above result confirms that MCP has been fabricated successfully.…”

Developing eco‐friendly anticorrosion coating has great demand for marine protection. Incorporation of nontoxic inorganic fillers into waterborne epoxy (WEP) coating shows tremendous potential for enhancing corrosion resistance. However, the application of MXene/WEP coating is limited by the poor dispersion of MXene in WEP and insufficient corrosion resistance. Herein, a polydopamine (PDA) modified MXene‐CeO2@PDA (MCP) filler was constructed by a combination of CeO2 with MXene and embedded into WEP to form eco‐friendly anticorrosion MCP/WEP coating. Dispersion of MXene in WEP is improved by the introduction of CeO2 and PDA modification. Benefiting from the synergy of the physical labyrinth effect of MXene and the chemical inhibition effect of CeO2, MCP/WEP coating exhibits remarkable anticorrosion behavior in 3.5 wt.% NaCl solution with a low corrosion rate of 4.46 × 10−6 mpy, which is three orders of magnitude lower than that of blank WEP (4.78 × 10−3 mpy). Moreover, MCP/WEP presents long‐term and stable corrosion protection for over 30 days. The results reveal the incorporation of MCP significantly promotes the anticorrosion performance of WEP.This article is protected by copyright. All rights reserved

“…The co-deposited Co-Mo alloy is expected to have superior wear and corrosion resistance properties, which will be beneficial for measuring phosphate levels in real-world matrices with varying pH. 20,23 For instance, Kidosaki et al have reported the development of Co-Fe alloy for electrochemical phosphate detection. 24 Zeitoun and Biswas have reported the development of Co-Mo alloy with high cobalt composition for detecting phosphate in laboratory standard solution.…”

Quantification of phosphate ions in water ecosystems is crucial for maintaining a healthy aquatic environment and optimizing aquaculture parameters. While cobalt (Co) thin-film-modified electrodes are widely used as phosphate sensors, their selectivity and stability often require improvements for on-site measurement. The present work addresses this challenge by introducing a novel phosphate sensing platform utilizing Cobalt-Molybdenum (Co-Mo) alloy film deposited on copper substrate. The developed Co-Mo thin film sensor exhibited a good thermal stability (up to 60°C) and significantly improved the detection ranges (10−6 M to 10−2 M). The influence of electrolyte pH and temperature toward potentiometric sensing of phosphate were investigated and the conditions were optimized to improve the sensor sensitivity. The sensor showed a sensitivity of -56 mV.dec-1 with a good correlation coefficient (0.988). The detection limit was determined to be 0.987 µM and the relative standard deviation (RSD) was 1.3% (n=3). The Co-Mo thin film sensor exhibited negligible interference even in the presence of 10-fold excess concentrations of common interfering analytes, demonstrating its robust performance in real-world environment. To validate the field practicality, the sensor’s performance was successfully tested in real shrimp culture water samples, demonstrating its compatibility with complex environmental matrices.
