Abstract CeO 2 hollow spheres (250–350 nm in diameter), with mesoporous shells of approximately 50 nm, were synthesized by a one‐pot, template‐free hydrothermal method. X‐ray diffraction (XRD), photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning (SEM), high resolution (HRTEM), and nitrogen adsorption–desorption measurements used to characterize the products. The formation these involves aggregation initial nanoparticles followed solid evacuation driven an...
Novel Zn-doped In2O3 nanocages and hollow spindle-like nanostructures (HSNs) have been prepared by calcining precursors obtained via a facile template-free hydrothermal method. The change in morphology, size, phase compositions controlled synthesis of the are achieved simple adjustments amount water. result this formation mechanism investigation reveals that water reaction time make significant contributions to growth nanostructures. driving forces for...
In this paper, a simple one-step hydrothermal method has been developed to prepare three-dimensional CeO2 microflower structures via cerium oxalate precursor. X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution (HRTEM), field-emission scanning (FE-SEM) and thermal gravimetric (TG) analysis were utilized characterize the products. Herein, unlike conventional calcination of precursor, oxalic acid acted not only as precipitator but also modifier morphology with...
Abstract Ceria nanoparticles with 4 and 7 atom‐% manganese dopant were synthesized through a template‐free solvothermal method. The structure of the samples was characterized by powder X‐ray diffraction (XRD). Monodispersed nanospheres average size 130 nm observed in transmission electron microscopy (TEM), high resolution (HRTEM), field‐emission scanning (FE‐SEM) analyses. Manganese ions introduced into system it is confirmed that Mn species dissolve within CeO 2 lattice Raman spectroscopy...
Uniform-sized and monodisperse CeO2 mesoporous hollow nanospheres composed of ceria nanocrystals were synthesized via a template-free surfactant-assisted benign hydrothermal route. On the basis time-dependent experiment, precipitation–dissolution–renucleation–assembly Ostwald ripening processes mechanism is proposed for formation spheres. Poly(vinyl-pyrrolidone) (PVP) was applied as surfactant to facilitate reassembly nanoparticles shell nanospheres. By increasing amount PVP, spheres could...
Noble metal nanoparticle-based catalysts are widely used for the removal of hazardous materials. During catalytic reactions, it is particular importance developing novel strategies to avoid leaching or sintering noble nanoparticles. Here, 4-nitrophenol (4-NP) and CO, typical chemicals in industrial water exhaust gases from vehicles, studied their using CeO2@Au@CeO2-MnO2 catalyst. The sandwich hollow structure achieved by means successive interfacial redox reaction without any surfactants...
In this paper, a facile and economical route based on an oxidation induced phase transformation in alcoholic solution was developed to prepare mesoporous CeO2 nanoflowers. The whole process could be divided into two steps: the formation of Ce(HCOO)3 with flower-like structures from unchanged morphology solution. TEM results revealed that nanoflowers consist rods length diameter 100 30 nm, respectively. N2 adsorption/desorption experiments indicated display mean pore size 4 BET surface area...
To elucidate the growth mechanism of Cu2O/MWCNTs synthesized by spontaneous redox reaction, evolution copper oxides was investigated during synthesis process. It found that pH reaction system and defects in MWCNTs play an important role for formation. According to calculation oxidation reduction potentials at different conditions, only 9 satisfies conditions formation thermodynamically presence NH3·H2O which is used adjusting system. The high defect density favorable dynamically. For redox,...
