Three environmentally friendly activated carbons with mainly micropores based on loofah sponge (LSC), as the adsorbents, were prepared through a simple carbonization process under argon atmosphere at 600°C, 800°C, and 1000°C. The adsorption properties of methylene blue on the LSCs were studied through varying the experimental parameters such as the temperature, pH, dosage and contact time. The adsorption...
Palladium nanotubes were prepared by using silver nanowires as the template, which were prepared in a modified polyol reduction process. The morphology and structure of silver nanowires and palladium nanotubes were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Electrochemical experimental data showed that palladium nanotubes...
The electrochemical performances of symmetric supercapacitors assembled by MnFe 2 O 4 colloidal nanocrystal clusters (CNCs) in aqueous electrolytes were investigated by using cyclic voltammetry, galvanostatic charge–discharge, cycle stability and electrochemical impedance spectroscopy. Results showed that the capacitance of MnFe 2 O 4 CNCs can be easily adjusted by...
A simple, green, microwave-assisted method of synthesizing silver nanoparticles was developed using sodium alginate as stabilizer and reducer. A possible mechanism involved in the reduction and stabilization of nanoparticles was investigated. The effect of reaction conditions such as the concentration of sodium alginate and AgNO3, irradiation time and pH on the synthesis of silver nanoparticle was...
Cobalt ferrite (CoFe 2 O 4 ) submicrospheres with tunable structures were synthesized by a one-pot solvothermal method through adjusting iron precursors. CoFe 2 O 4 submicrospheres were characterized by a series of technologies including X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectrometry...
