Effect of annealing on the structural, optical, electrical and photocatalytic activity of ZrO2–TiO2 nanocomposite thin films prepared by sol–gel dip coating technique

Nanocomposite Coatings: Preparation, Characterization, Properties, and Applications

“…In case of inorganic matrix, the second phase can be added to sol-gel for inorganic nanofillers, such as the I/I coatings [49][50][51][52]. In the case of organic matrix, a wellknown approach to generate inorganic nanophases within an organic matrix is to utilize sol-gel chemistry [18].…”

“…For inorganic matrix, such as metal matrix or alloy matrix, these nanocomposite coatings could be prepared by various methods, including chemical vapor deposition (CVD) (see Figure 3), powder metallurgy, physical vapor deposition (PVD) [41][42][43][44][45], thermal plasma spray [46][47][48], sol-gel [49][50][51][52] (see Figure 1), epitaxial growth [53], cold spray [54][55][56][57][58][59][60][61] (see Figure 2), and electrodeposition [62][63][64][65][66][67]. Metal matrix composite coatings that dispersed a second phase [68,69] have attracted extensive attention owing to unique properties such as oxidation and corrosion resistance [69,70], wear resistance [71,72], and magnetic properties [72].…”

“…In these coatings, one metal may be converted into nitride in the nanocrystalline phase and the other may be transported into the growing film unreacted. On the other hand, thermal posttreatment has strong effect not only on the grain size [50,59], crystallization [154], and morphology [168] but also on the dislocation density and the interactions between nanoparticles and the matrix [46] or the bonding of microstructural phases [47].…”

Synthesis, Crystal Structure, and Thermophysical Properties of ZrTiO4 Nanoceramics

“…Materials based on zirconium titanate are of significant interest due to a wide range of applications . As an example, ZrTiO 4 can be drawn on as a material for a chemo-resistive gas sensor [1], an element of hydrophilic ultrafiltration membranes [2][3][4], catalysts and catalyst carrier [5][6][7][8][9]. In the literature, functional materials based on zirconium titanate are demonstrated as promising candidates for application in optics [10][11][12][13][14], medicine [15,16], microelectronics [17,18], and other branches of industry and technology [19][20][21][22][23][24][25][26][27][28][29].…”

Deposition of Photocatalytic TiO2 Coating by Modifying the Solidification Pathway in Plasma Spraying

“…Several methods have been reported to prepare TiO 2 coatings, including vapor deposition [6,7], electrophoretic deposition [8,9], sol-gel [10], and thermal spraying [11]. In comparison to other methods, thermal spraying has several highlighted features to make it particularly attractive, which include flexibility and high efficiency.…”
