“…This was most likely due to the higher content of small and well-distributed ceria particles in this composite coating, compared to Zn-Co-CeO 2 (CeO 2 powder), which can play a role as nanofillers of the pores leading to the reduction of diffusion paths of the electrolyte through the coating. Also, ceria is a well-known corrosion inhibitor, and the shift of the Volta potential to more positive values during this time could be due to precipitation of ceria on the active sites, manifesting a healing effect [30][31][32]. These results were in a good agreement with EIS results.…”

Electrodeposition and characterization of novel ceria-doped Zn-Co composite coatings was the main goal of this research. Electrodeposited composite coatings were compared to pure Zn-Co coatings obtained under the same conditions. The effect of two ceria sources, powder and home-made sol, on the morphology and corrosion resistance of the composite coatings was determined. During the electrodeposition process the plating solution was successfully agitated in an ultrasound bath. The source of the particles was found to influence the stability and dispersity of plating solutions. The application of ceria sol resulted in an increase of the ceria content in the resulting coating and favored the refinement from cauliflower-like morphology (Zn-Co) to uniform and compact coral-like structure (Zn-Co-CeO2 sol). The corrosion resistance of the composite coatings was enhanced compared to bare Zn-Co as evidenced by electrochemical impedance spectroscopy and scanning Kelvin probe results. Zn-Co doped with ceria particles originating from ceria sol exhibited superior corrosion resistance compared to Zn-Co-CeO2 (powder) coatings. The self-healing rate of artificial defect was calculated based on measured Volta potential difference for which Zn-Co-CeO2 (sol) coatings exhibited a self-healing rate of 73.28% in a chloride-rich environment.

“…[ 44 ] In addition, for pure CdS and hierarchical BiOI/MoS 2 /CdS heterostructured microspheres, the narrow peaks at 2844 and 2912 cm −1 can be ascribed to the symmetrical stretching vibration of CH bond of CH 3 functional group, which might be attributed to residual cetyltrimethylammonium bromide during the synthesis process.

Efficient photocatalytic CO2 reduction into clean chemical fuels using visible light remains an enormous challenge. Construction of hierarchical heterostructured photocatalysts has gained tremendous popularity due to their distinctive structural characteristics and synergetic effect that they can boost the visible‐light photoactivities. Based on this, a three‐step solvothermal method is proposed to construct hierarchical BiOI/MoS2/CdS heterostructured microspheres. The addition of MoS2 and CdS not only plays a significant role in the improvement of visible‐light absorption, but also works as a carrier electron mediator, inhibiting the recombination of electrons–holes effectively. High CH4 yield (46.22 μmol h−1 g−1) and CO yield (36.98 μmol h−1 g−1) are achieved for BiOI/MoS2/CdS‐0.03 heterostructured microspheres under simulated sunlight irradiation because of the wide solar light‐driven response, abundant active sites and high charge separation ability. Therefore, this study provides an efficient strategy for constructing heterostructured catalysts with remarkable visible‐light response photocatalytic CO2 reduction activity.

“…The larger the impedance modulus is, the better the anti-corrosion performance of the coating will be. 28 It can be seen from Fig. 7 that the capacitive arc radius of the pure water-based acrylic coating decreased sharply after being immersed for 24 h, and the capacitive arc radius of the Mn-MOFs@acrylic coating decreased slowly after being immersed for 48 h. The capacitive arc radius of the Mn-MOFs@Zn@acrylic coating increased with the increase of the immersion time, indicating that the zinc phosphate was successfully released and a new protective film had been formed on the scratches, which delays the further corrosion of mild steel.…”
