Highly efficient visible light active Cu–ZnO/S-g-C3N4 nanocomposites for efficient photocatalytic degradation of organic pollutants

“…15 Different techniques, including doping with ions and composite formation with semiconductors, were employed to overcome the inherent deciencies of ZnO. 16,17 Metal ion-doped ZnO has improved visible light absorption and photocatalytic activity. [18][19][20] Various transition elements, such as Ni, Fe, Cr, Mn, and Cu, have been used to elevate the photocatalytic efficiency of ZnO.…”

Multifunctional application of PVA-aided Zn–Fe–Mn coupled oxide nanocomposite

“…4e. During heterojunction, until the Fermi level equalizes, the energy band of metal oxides starts to move up and down by transferring electrons [8,43] and lead to the creation of a depletion layer in the interface [44]. The Fermi level of p-type Mn 2 O 3 exists near the VB.…”

Ternary nanocomposite of ZnFe2O4/α-Fe2O3/ZnO; synthesis via coprecipitation method and physical properties characterization

“…Composites with all phases in nanoscopic dimensions have high potential of applications in various areas like catalytic activities also for homogeneous doping and incorporation in materials matrix for filtering and sensing, nowadays [1][2][3][4][5][6][7]. In this class of heterogeneous materials, binary composites of zinc ferrite (ZnFe2O4), hematite (α-Fe2O3) and zinc oxide (ZnO) as the highly interesting semiconducting transition metal oxides (TMOs) have received much research attention [1,8,9]. However, successfully preparation of ternary composite of these nanoparticle through one approach has been reported in few works yet [10,11].…”

“…There are different methods to prepare TMO semiconductor nanocomposites, including sol-gel method [6,[35][36][37], sonochemical [38,39], hydrothermal [1,10,11], microwave combustion [34,40,41], and coprecipitation [42,43]. Among various chemical methods for synthesis, coprecipitation process has several advantages compare with other methods including, good homogeneity, low cost, high purity of product and not requiring organic solvents.…”
