A simple and inexpensive technique to fabricate patterned arrays of monodisperse nickel nanoparticles by the reduction of nickel (II) sulfate with sodium hypophosphite (NaH 2 PO 2 ) using an organic self-assembled monolayer as a template is reported. Monodisperse nickel nanoparticles on self-assembled monolayer (SAMs) templates of 4-(11-mercaptoundecyl)benzene-1,2-diol (MBD) were prepared...
Honeycomb Ag/ZnO heterostructures exhibiting rapid photocatalytic activity were successfully prepared via simple solution combustion synthesis (SCS). Brunauer–Emmett–Teller surface area of the prepared Ag/ZnO heterostructures are 46.7m 2 /g, and the pore size distribution curves indicate its excellent mesoporous nature. In addition, Raman spectrum and the X-ray photoelectron analysis results...
Three-dimensional flower-like SnO 2 /Ag heterostructures were self-assembled via a simple microwave hydrothermal treatment of a mixture of tin (II) dichloride dihydrate (SnCl 2 ·2H 2 O), sodium citrate (Na 3 C 6 H 5 O 7 ·2H 2 O) and silver nitrate (AgNO 3 ) in an alkali solution. The morphological, structural and optical properties...
A UV light-assisted route has been used to synthesis coral SnO 2 nanoparticles. Annealing is introduced to crystallize samples and exclude impurities without changing the morphology. Powder X-ray diffraction (XRD), thermo-gravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and UV–vis spectra are used...
Mn-doped ZnO nanorods (composition: Mn 0.046 Zn 0.954 O) were grown by a simple solvothermal technique. The morphological, structural and optical properties of the as-prepared nanorods were investigated by means of transmission electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction, and photoluminescence. The results showed that the sample had rod-like...
Poly(vinyl pyrrolidone)-capped bismuth nanospheres were synthesized by a simple and convenient wet chemical method. In the process, bismuth nitrate was reduced by ethylene glycol in the presence of poly(vinyl pyrrolidone) (PVP) at 185°C in air. PVP was used as a protecting agent to prevent oxidation of the sperical bismuth particles. PVP molecules were absorbed on the surface of bismuth nanospheres...
