Self-assembly of ZnO nanoparticles and subsequent formation of hollow microspheres

Fabrication, characterization and photocatalytic activity of La-doped ZnO nanowires

“…Thereby, diverse morphologies of ZnO nanostructures have been synthesized for different applications [8][9][10]. The decrease of the size of ZnO nanostructures is feasible to obtain more surface area and great efforts have been made to decrease the crystal size and enlarge the ratio of surface to volume [11,12].…”

Single-crystalline Ag2S hollow nanoparticles and their ordered arrays

“…In our reaction system, the growth mechanism of rhombic hollow nanoparticles may be similar to that of hollow Cu 2 O nanocubes and nanopolyhedra [26]. The Ag + combine with S 2 O 3 2− in the solution to form soluble Ag(S 2 O 3 ) − and Ag(S 2 O 3 ) 2 3− [27], and as illustrated in Fig. 5, they can electrostatically interact with the surfactant cationic head groups, CTA + , to produce CTA + -Ag(S 2 O 3 ) − and CTA + -Ag(S 2 O 3 ) 2 3− ion pairs, respectively (step a).…”

“…Monodisperse hollow nanoparticles can be used to fabricate lightweight structural ordered arrays through "bottom-up" assembly, which exhibit new, tunable physical properties and hold considerable technological promise for device applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The construction of ordered arrays requires the building block hollow nanoparticles to be uniform in size and shape but has been difficult to achieve.…”

“…The construction of ordered arrays requires the building block hollow nanoparticles to be uniform in size and shape but has been difficult to achieve. The successful examples of hollow nanoparticle arrays mainly include Si [4], Fe 3 O 4 [5,6], SiO 2 [7], Ni(OH) 2 [8], Au [9,10], Ag [11], TiO 2 and SnO 2 [12], Ni [13,14], and polystyrene [15]. Single-crystalline hollow nanoparticles are expected to have superior properties because of their anisotropic behavior, large surface area, and low material density.…”

Synthesis and photocatalytic performance of ZnO hollow spheres and porous nanosheets

“…It is well known that the photocatalytic degradation performance of materials is influenced by many factors, such as size, morphology, defects and so on [15][16][17][18]. Some reports believed that the absorption ability is the key factor to determine the photocatalytic activities of ZnO nanomaterials so that they paved their efforts to synthesize ZnO nanomaterials with different morphologies such as nanotubes, hollow spheres and so on [19][20][21]. Meanwhile, some researchers believed that the intrinsic defects of ZnO are beneficial to setup catalytic systems, which are expected to degrade the environmental contaminants with high efficiency [22][23][24][25].…”
