Fabrication of mesoporous ZnO nanosheets from precursor templates grown in aqueous solutions

Advances in nanostructured thin film materials for solar cell applications

“…Martinson reported that the surface morphologies of ZnO are more amenable in comparison to TiO 2 which increases the dye loading capacity and decreasing the recombination effect inside the DSSC. Many ZnO nanostructures have been fabricated, including nanowires, nanoparticles, nanocombs, nanoflowers, nanobelts, nanoflakes, nanoclusters, nanotubes, porous nano-sheets, nano-colloids, and nano-powders [113][114][115][116][117][118]. The results of the DSSCs were made by the ZnO nanotubes, nanowires and other 1D to 2D nanostructured photoanodes indicated that the special morphology can provide a unique advantage for electron transport.…”

Microwave-assisted synthesis of ZnO micro-javelins

“…Bands at 710 cm À1 and 739 cm À1 probably correspond to the n 4 CO 3 2À vibrations and the one at 836 cm À1 corresponds to the n 2 CO 3 2À vibration. 37,38 All the samples showed a band at 1385 cm À1 indicating the presence of nitrate species complexed with the metal ion. 39 The bands at 1360, 1550 and 1587 cm À1 may be assigned to the symmetric and antisymmetric vibrations of carbonate.…”

Morphology Control of Metal Oxide Nanocrystals

“…1000 nm 53 and specular films consisting of flowers with well-formed triangle features 59 in aqueous solutions. However, ZnO films have usually been prepared on substrates 54,57,[60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76] , and in particular crystalline ZnO films having high c-axis orientation require expensive substrates such as single crystals or highly-functional substrates. A simple and low-cost process for selfsupporting crystalline ZnO films is expected to be used for a wide range of applications such as windows of optical devices or low-value-added products.…”
