“…As outlined in our previous study [8], when electrodepositing pure tin-nickel coatings with a composition of 65 wt.% Sn-35 wt.% Ni, the bath's Sn content was kept within the range of 20-25 g/L, while the Ni content fell within the range of 55-65 g/L. To maintain these concentrations during the electrodeposition of the Sn-Ni/TiO 2 composite coatings, continuous monitoring of both the tin and nickel content was carried out through titration.…”

“…Moreover, in recent years, there has been growing scientific and technological interest in the development of metal matrix composite coatings that incorporate TiO 2 nanoparticles. These composite coatings offer improved mechanical properties, and exhibit intriguing photocatalytic behavior when exposed to UV light [6][7][8][9][10][11][12]. TiO 2 is a semiconductor that has been extensively studied, and its physicochemical properties can vary depending on factors such as nanoparticle shape, size, and the predominant crystalline phase present.…”

Sn–Ni alloy matrix coatings co-deposited with TiO2 nanoparticles (Evonik P25) were produced utilizing direct (DC) and pulse electrodeposition (PC) from a tin–nickel chloride-fluoride electrolyte with a loading of TiO2 nanoparticles equal to 20 g/L. The structural and morphological characteristics of the resultant composite coatings were correlated with the compositional modifications that occurred within the alloy matrix and expressed via a) TiO2 co-deposition rate and b) composition of the matrix; this was due to the application of different current types (DC or PC electrodeposition), and different current density values. The results demonstrated that under DC electrodeposition, the current density exhibited a more significant impact on the composition of the alloy matrix than on the incorporation rate of the TiO2 nanoparticles. Additionally, PC electrodeposition favored the incorporation rate of TiO2 nanoparticles only when applying a low peak current density (Jp = 1 Adm−2). All of the composite coatings exhibited the characteristic cauliflower-like structure, and were characterized as nano-crystalline. The composites’ surface roughness demonstrated a significant influence from the TiO2 incorporation rate. However, in terms of microhardness, higher co-deposition rates of embedded TiO2 nanoparticles within the alloy matrix were associated with decreased microhardness values. The best wear performance was achieved for the composite produced utilizing DC electrodeposition at J = 1 Adm−2, which also demonstrated the best photocatalytic behavior under UV irradiation. The corrosion study of the composite coatings revealed that they exhibit passivation, even at elevated anodic potentials.

To address environmental pollution and energy shortage issues, titanium dioxide (TiO2)-based photocatalysts, as an efficient pollution removal and fuel production technology, have been widely used in the field of photocatalysis. In practical applications, TiO2-based photocatalysts are usually prepared on various substrates to realize the separation of the catalyst from water and improve photocatalytic stability. Herein, the research progress of TiO2-based heterogeneous photocatalytic coatings deposited on glass substrates with various deposition techniques is reviewed. Such TiO2-based composite coatings obtained using different techniques showed excellent self-cleaning, pollution removal, air purification, and antibiosis performance. The various deposition techniques used for the preparation of TiO2 coatings, such as wet chemical deposition (WCD), electrodeposition, physical vapor deposition (PVD), and chemical vapor deposition (CVD) were discussed together with photocatalytic applications by highlighting the typical literature. Finally, the challenges and prospects of developing TiO2-based heterogeneous coatings were put forward.

Immobilized TiO 2 photocatalyst is considered as a promising approach to fabricate high-performance and available materials for wastewater treatment. The immobilization of TiO 2 particles can be performed by various manufacturing techniques, the electrochemical deposition being the most convenient and tunable method. This chapter surveyed the literature data on electrochemical synthesis of TiO 2 -containing composites with photocatalytic performance. The electrochemical deposition and characterization of iron/titania composite coatings were considered in detail. The content of TiO 2 dispersed phase in the fabricated composites was up to about 5 wt.%. The electrodeposited Fe-TiO 2 composites exhibited photocatalytic properties regarding the photochemical degradation of methylene blue and methyl orange organic molecules in water solution. The apparent rate constants of photochemical degradation of the examined organic dyes on the electrodeposited Fe-TiO 2 photocatalyst were in the range of (1.8-12.8) × 10 −3 min −1 .
