A high yield of the dimer-type heterostructure Ag/ZnO nanocrystals with different Ag contents is successfully prepared through a simple solvothermal method in absence surfactants. The samples are characterized by X-ray diffraction, transmission electron microscopy, photoelectron spectroscopy, UV-vis and IR spectroscopy. results show that all composed metallic ZnO; nanoparticles locate on surface ZnO nanorods; binding energy 3d(5/2) for sample content 5.0 atom % shifts remarkably to lower...
Low-dimensional ZnO nanocrystals with controlled size, aspect ratio, and oxygen defects (e.g., type concentration) are successfully prepared through simple solvothermal thermal treatment methods. The structure of the as-synthesized samples is characterized by XRD, N2 physical adsorption, TEM, IR XPS spectra. results show that ratio size increase increasing [OH-]/[Zn2+]; morphology evolves from nanorod to nanoparticle an in annealing temperature; BET surface areas corresponding decrease...
Ag/ZnO heterostructure nanocatalysts with Ag content of 1 wt % are successfully prepared through three different simple methods, where chemical reduction and photolysis reaction adopted to fabricate the heterostructure. The dispersity clusters and/or nanoparticles in nanocatalyst is investigated by EDX mapping XPS techniques. experimental results show that deposition−precipitation an efficient method synthesize highly dispersed nanoparticles; photocatalytic activity photocatalysts mainly...
A network-structured SnO(2)/ZnO heterojunction nanocatalyst with high photocatalytic activity was successfully synthesized through a simple two-step solvothermal method. The as-synthesized samples are characterized by X-ray diffraction, photoelectron spectroscopy, transmission electron microscopy, scanning N(2) physical adsorption, and UV-vis spectroscopy. results show that the sample molar ratio of Sn/Zn = 1 is mesoporous composite material composed SnO(2) ZnO. nanocatalysts for degradation...
In this work, we study the enhancement of Raman signals and photocatalytic activity Ag/ZnO heterojunctions with an Ag content 1 at.%, which were synthesized by photochemical deposition nanoparticles onto pre-synthesized ZnO nanorods. A strong interaction between nanocrystals evidenced XPS UV-vis spectroscopy. The binding energy shifts toward lower compared to that pure nanoparticles, revealing electrons transfer from nanocrystals. red shift plasmon absorption peak in further confirms two...
The activation of H2O is a key step the COS hydrolysis, which may be tuned by oxygen vacancy defects in catalysts. Herein, we have introduced Cu into Co3O4 to regulate defect content In situ DRIFTS and XPS spectra reveal that are adsorbed activated vacancy. 10 at% doped sample (10CuCo3O4) exhibits optimal activity, 100% conversion at 70 °C. improved vacancies CuCo3O4 accelerate form active OH. binds with hydroxyl intermediate HSCO2−, then –OH on reacts HSCO2− HCO3−. Meanwhile, catalyst high...
The conversion of H2S to high-value-added products is appealing for alleviating environmental pollution and realizing resource utilization. Herein, we report the reduction nitrobenzene aniline using waste as a "hydrogen donor" over catalyst FeCeO2−δ with abundant oxygen vacancies (Ov), especially an asymmetric vacancy (ASOv). electron-rich nature ASOv sites facilitates electron transfer electron-deficient nitro group, promoting adsorption activation Ph–NO2 through elongation cleavage N–O...
In this paper, we report a template-engaged strategy for the synthesis of Co–Mn oxides with double-shell box-in-box hollow nanocage (BHNC) structures.
