Adsorption capacity and coke formation of titanium oxide increase, but their photooxidation activity decrease as partical size of TiO2 rises..[r]

4. Conclusion
In summary, we have developed a facile hydrothermal method for the preparation of dandelion-like ZnO nanostructures by using aqueous ammonia solutions, at relatively low temperatures. The XRD, UV–visible, and PL studies reveal that the as-prepared 3D ZnO nanostructure[r]

The photocatalytic performance of as-synthesized ZnO and V2O5-ZnO structures was estimated via photodegradation of methylene blue MB solution under visible light irradiation as depicted [r]

Fig. 2 b shows the FESEM image of V 2 O 5 -ZnO nano fl akes. It is well known that tiny porous nanostructures play an important role in optoelectronic device applications. In the V 2 O 5 -ZnO product, one can apparently see it appearing in the fl ake-type structure with small pores that[r]

When we use distilled water as a solvent, ZnO nanoparticles has ellipse shape and large size with size of larger axis is about 100 nm and size of the other axis is about 40 nm. In addition, the size distribution is not very narrow. With ethanol as solvent, the obtained[r]

nanoparticles (including P25, P90, and home-made hydrothermal nanoparticles) were used to prepare various hybrid films. Results show that, in general, the integration of ZnO with TiO 2 is a powerful means to improve the efficiency of the photoanode of DSCs, with the improvement up to 150%[r]

Furthermore, when ZnO nanoparticles were stimulated by the UV irradiation for about 180 s, we can notice that the electrode impendence was extremely decreased, caused
by the caner cells massive death in a short culture time (shown in Supporting Information). Compared with Figs. 3 b, 4 b and[r]

Synthesis of pyrano-chromenes and pyrano-pyrans was developed by three-component reactions of kojic acid and aromatic aldehydes with dimethone and malononitrile, catalyzed with nano-Bi2O3-ZnO and nano-ZnO, respectively.

In this work, the hydrothermal growth of ZnO nanorods (NRs) on plastic PVC substrate is presented. It was shown that ZnO NRs with high density and high crystallinity can be successfully grown by implementing saturated nutrition solution of zinc nitrate hexahydrate (Zn[NO3]2·6H2O) and hexamethylenete[r]

To discuss the stability of the predicted nanoporous ZnO structures, we calculated the total binding energy per ZnO-pair vs volume and the bulk modulus by nonlinearly fitting ob[r]

The sensitized anode for DSCs is preferred to be an excellent electron conductor, and its conduction band should match the dye’s LUMO (the lowest unoccupied molecular orbitals). Furthermore, a tightly chemical binding interface is necessary for electron-transfer from dye to TiO 2 and between the[r]
