By kinetically controlled vapor-diffusion catalysis, nanostructured ZnO and Zn5(OH)8(NO3)3*2H2O thin films have been grown on substrates with different chemical compositions and varying degrees of crystallinity. The materials resulting from heterogeneous nucleation under mild conditions (starting from aqueous metal salt precursor solutions at room temperature) were characterized by X-ray diffra...

With increasing production and applications of nanostructured zinc oxide, e.g., for biomedical and consumer products, the question of safety is getting more and more important. Different morphologies of zinc oxide structures have been synthesized and accordingly investigated. In this study, we have particularly focused on nano-micro ZnO tetrapods (ZnO-T), because their large scale fabrication h...

Aerosol materials synthesis methods [ 1–9 ] have been utilized to prepare a distinct platform of spherical composite materials that incorporate sub-100 nanometer features.

Here, a simple electrodeposition method to synt...

In the present contribution, a facile and efficient protocol for synthesis a nanohybrid structure of core-coronal-shell ZnO@ZIF-8 using ascorbic acid (ZnO@AA/ZIF-8) as a new adsorbent for arsenic removal from water has been represented. For this purpose, the ZnO nanospheres were synthesized by a green and simple method followed by coating with ascorbic acid (AA) to modify their surface to achie...

Photon upconversion materials are attractive for a wide range of applications from medicine, biology to photonics. Among them, ZnO is of particular interest owing to its outstanding combination of materials and physical properties. Though energy upconversion has been demonstrated in ZnO, the exact physical mechanism is still unknown that prevents a control of the processes. Here, we show that d...

Nanostructured ZnO was prepared using a facile solution-phase method at room temperature without need to calcination. Oxidation of zinc sulfate by sodium hypochlorite in the presence polyethylene glycol (PEG) and hydroxide (NaOH) gave pure nanostructured oxide (ZnO-NPs). The structure physicochemical properties material were determined X-ray powder diffraction (XRD), Fourier-transform infrared ...
