Mg doping induced high structural quality of sol–gel ZnO nanocrystals: Application in photocatalysis

Microstructure and photocatalytic properties of polyimide/heterostructured NiO–Fe2O3–ZnO nanocomposite films via an ion-exchange technique

“…[2][3][4][5][6] However, the low optical response of ZnO over the entire solar spectrum and the rapid recombination of photo induced electrons and holes weaken its photocatalytic efficiency. To improve its photocatalytic efficiency, various techniques such as doping, [7][8][9][10][11] modifying by organics, 12 fabricating heterostructured metal oxides [13][14][15][16][17][18][19][20][21] and reducing particle size have been performed. 22 The single method of these approaches has resulted in the improvements of catalytic properties but only to a limited extent.…”

Effect of Mn doping on structural, optical and photocatalytic behaviors of hydrothermal Zn1−xMnxS nanocrystals

“…Recently, the efficient charge separation is considered as the principal factor for the high photocatalytic activity of ZnO:Mg nanocrystals under sunlight irradiation [59].…”

Soft synthesis of potassium co-doped Al–ZnO nanocomposites: a comprehensive study on their visible-light driven photocatalytic activity on dye degradation

“…One such potential material is the use of ZnO, which possesses properties such as, high oxidative capacity, low cost, high chemical stability, and low toxicity [18,19]. Besides, ZnO also has a wide band gap (*3.3 eV) with a high excitation binding energy of *60 meV, wurtzite crystal structure, and piezoelectric properties [20,21]. However, the faster recombination effect of the photogenerated charge carriers in the case of ZnO materials is the major setback in the process of photocatalysis, as it reduces the overall quantum efficiency.…”
