Nanoparticles of Co-doped ZnO with 3·8, 7·2 and 11·5wt% were synthesized by solvothermal method through oxalate precursor route. X-ray diffraction studies showed the formation of hexagonal ZnO structure for x= 0·038, however, secondary phase of Co3O4 arises on increasing the Co content...
valence and carrier type from extremely Co doped ZnO to ZnCo2O4 Bastian Henne1, Verena Ney1, Katharina Ollefs2, Fabrice Wilhelm2, Andrei Rogalev2 & Andreas Ney1 We have investigated the relation between local structure, valence and carrier type with magnetism in the Zn-Co-O ...
ion transport has been described as repeated coordination/dissociation of ions among these complexation sites facilitated by molecular chain motions and bond rotations. Thus, a flexible polymer composed of polar segments, such as −O−, −OH, and −C=O should be an optimal choice for high...
[74] used the Langmuir–Blodgett method to synthesize an artifi- cial interfacial film of N-doped GO (NGO) in one step and obtained an ultrathin and parallel interfacial layer to modify the Zn anode (Fig. 4d). The parallel NGO lamellae could adjust the deposition sites of Zn2+ ...
Flexible all-solid-state high-power supercapacitor fabricated with nitrogen-doped carbon nanofiber electrode material derived from bacterial cellulose A low-cost high-performance solid-state flexible asymmetric supercapacitor (ASC) with 伪-MnO2 nanowires and amorphous Fe2O3 nanotubes grown on flexible car...
The average particle size of TiO2 NPs was decreases (38 to 28 nm) while the band gap energy was increases (3.35 eV–3.85 eV) with increasing the amount of Zn-doping. Cellular data demonstrated that Zn-doped TiO2 NPs induced cytotoxicity (cell viability reduction, membrane damage and...
In this work, zinc chromite (ZnCr2O4) nanostructures have been synthesized through co-precipitation method. The effect of various parameters such as alkaline agent, pH value and capping agent type was investigated on purity, particle size and morphology
Pure Co3O4 and ZnCo2O4 (Co/Zn: 9/1, 8/2 and 7/3) nanostructured thin films were successfully deposited on the glass and indium tin oxide substrates from ac... H Behzad,FE Ghodsi - 《Journal of Materials Science Materials in Electronics》 被引量: 1发表: 2016年 Physical vapour deposit...
近年来,二元金属氧化物A_xB_(3-x)O_4在高级氧化过程中受到了广泛的关注,其中CuFe2O_4、CoFe2O_4和CoMn2O_4已被报道可激活过一硫酸钾(PMS)降解有机污染物。然而,截至目前,关于二元金属催化剂激活更加经济的过硫酸钾(PS)的报道还较少。除此之外,双金属催化剂激活PS/PMS过程中,每种金属在其中的催化作用仍...
The synthesis of compounds containing several different compounds can maintain their properties in the final product, especially if the final composition i
