چکیده
Experimental details Preparation of Fe3O4 micro-spheres The mono-dispersed Fe3O4 micro-spheres were synthesized by a one-pot hydrothermal method. In a typical synthesis, FeCl3.6H2O (0.54 g), sodium citrate (1.2 g), and urea (0.2 g) were dissolved in distilled water (40 mL). Then, PAAS (0.2 g) was added under continuous stirring until it was totally dissolved. The solution was transferred to a 50 mL Teflon-lined autoclave, which was then sealed and maintained at 200oC for 12 h. The product was separated by magnetic separation, washed with distilled water and absolute ethanol several times, and then dried in a vacuum oven at 60 C overnight.

متن کاملOxygen reduction reaction on Pt/C at the presence of super paramagnetic of Fe3O4 nanoparticles for PEMFCs
In this paper the role of super paramagnetic iron oxide nanoparticles (SPI) on Platinum nanoclusters on activated carbon (Pt/C) for electrocatalytic oxygen reduction reaction was considered. Four composites of Pt/C and super paramagnetic iron oxide nanoparticles were prepared with the same total composites weight and different loading of Pt/C (1.2, 0.6, 0.4 and 0.3 mg ). The composite attached ...
متن کاملA visible light driven doped TiO2 nanophotocatalyst: Preparation and characterization
A useful nanophotocatalyst (La,S-TiO2) was prepared by a sol-gel method and characterized by UV–vis diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), photoluminescence emission spectroscopy (PL) and scanning electron microscopy (FESEM). The results showed that the La,S-TiO2, which calcined at 550 °C, contained only anatase phaseand its crystal size was 23 nm...
