Preparation, characterization and application of Fe3O4/ZnO core/shell magnetic nanoparticles

Thermal Properties of Beeswax/CuO Nano Phase-change Material Used for Thermal Energy Storage

“…CuO nanoparticles were synthesized by the sol-gel method (Hong et al, 2008;Taufik et al, 2015). First, CuSO 4 .5H 2 O was dissolved in 100 ml of deionizer water.…”

Preparation, characterisation and activity evaluation of CaCO3/ZnO photocatalyst

“…Therefore, improving the photocatalytic activity by modification and change of the optical absorption properties has become a hot topic among researchers in the recent years [4,5]. One way is doping transition metal ions into a semiconductor photocatalyst [6][7][8][9], and the other is doping non-metallic elements, such as nitrogen, fluorine, sulphur, carbon, etc. into the substitutional sites in the crystal structure of a photocatalyst [10][11][12][13][14].…”

“…It is known that the n-n type and p-n type composite photocatalysts, such as ZnO/In 2 O 3 , ZnO/SnO 2 , NiO/TiO 2 and p-ZnO/TiO 2 etc., have been investigated extensively [15][16][17][18]. The results showed that the photocatalytic activity of the coupled photocatalyst was higher than that of the single one [19][20][21][22][23][24]. In addition, some inert substance-semiconductor coupled photocatalysts, such as SiO 2 /TiO 2 , BaSO 4 /TiO 2 , montmorillonite/TiO 2 and carbon/TiO 2 also had higher photocatalytic activity [25][26][27][28].…”

Synthesis of ZnO/CuO and TiO2/CuO nanocomposites for light and ultrasound assisted degradation of a textile dye in aqueous solution

“…can be indexed to the hexagonal wurtzite of ZnO and monoclinic phase of CuO, while all diffraction peaks of TiO 2 /CuO nanocomposites corresponded to the anatase phase of TiO 2 and monoclinic phase of CuO. The values of crystallite size calculated from Scherrer's formula [12][13] and the lattice parameters obtained from are tabulated in Table 1. Fig.2.…”
