A simple and versatile approach has been developed to synthesize multi-walled carbon nanotubes/metal-doped ZnO nanohybrid materials (MWNT/M-doped ZnO) by means of the co-deposition method. The experimental results illuminate that MWNTs can be modified metal-doped nanoparticles at 450 °C, such as Mn, Mg, Co elements. Furthermore, MWNT/Mg-doped hybrids have proven a high photocatalytic ability for methyl orange (MO), in which degraded rate MO reaches 100 % 60 min. enhancement activity is...
Large-scale ultra-long (even up to several centimeters) α-Si3N4 nanowires have been prepared using N2 as the nitrogen source, SiO or a mixture of Si and SiO2 silicon Ar barrier gas, CH4 reducing gas by simple catalyst-free CVD route under superatmospheric pressure conditions. The grown on ceramic boat corundum substrates, with lengths millimeters, even centimeters, average diameters around 40nm, were composed single-crystal core along [210] direction amorphous shell about 1–10 nm thick....
Multi-walled carbon nanotubes (MWNTs)/Cu-doped ZnO composite powders were prepared by co-precipitation method, and characterized X-ray diffraction, electron microscopy, fluorescence spectrum, ultraviolet spectrum. Experimental results show that the MWNTs can be modified Cu-doped nanoparticles with hexagonal wurtzite structure after annealed at 450 °C, nanoparticle size is about 15 nm. Two (UV) peaks a green band centered 510 nm are observed in spectrum of MWNTs/Cu-doped powder °C....

Abstract Multi-walled carbon nanotubes/Mg-doped ZnO (MWNTs/Zn 1-x Mg x O) nanohybrids were prepared by co-precipitation method, and their photocatalytic activity for methyl orange (MO) was studied. Experimental results showed that Mg-doped nanoparticles successfully deposited on the surface of MWNTs under annealing at 450 °C 550 °C. The resultant MWNTs/Zn 0.9 0.1O had better degradation than pure ZnO: rates MO photodegradation 100 % 30 1 h, respectively. enhancement in attributed to...
Arrays of single crystal germanium nanowires were fabricated in a self-assembled manner by hydrothermal method without any metallic catalyst or templates. SEM, TEM, HRTEM, SAED, EDS, FTIR analyses show that the are composed core and very thin GeO2 shell, have smooth surface straightforward body, uniform diameters, rectangular growth sectional view, knife edge tip. In process, H+ OH− play an important assistant role, role oxidation-reduction PL shows intensive purple light emission at about...
Novel silicon oxide nanojunction structures with various shapes, such as X type, Y T ringlike and treelike, are fabricated in a self-assembled manner by the hydrothermal method without any metallic catalyst. In nanojunctions, both nanowire part junction consist of same chemical composition, forming homogeneous homojunctions being made suitable for application nanoscale optoelectronics devices. The formation nanojunctions may be influenced surrounding environment reaction kettle, growth space...
Large-scale amorphous silicon oxide nanowires (SiONWs) have been synthesized from monoxide powder under supercritically hydrothermal conditions. The chemical bonding of SiONWs were investigated with Fourier-transform infrared (FTIR) spectrometry and near-edge x-ray absorption fine structure (NEXAFS) spectrometry. Our results show that the are tens microns long a diameter to hundreds nanometers. Selected area electron diffraction (SAED) shows samples amorphous. Energy dispersive (EDX)...
