The 23 full-factorial Central Composite Design (CCD) and response surface methodology (RSM) was applied to explain the effect and interaction of three factors in the process of Fe3O4/SiO2 nanoparticle: NaOH dosage, Fe3O4/SiO2 ratio and Fe2+/Fe3+ ratio. For the CCD optimization purposes, the canonical parameters was employed where the predicted average size of the nanoparticles was 115.39 nm, and the...
Carbon nanotubes (CNTs) doped vanadium pentoxide (V2O5) porous aerogels are a good kind of material as the cathode material in lithium batteries due to their layered structure, high energy density, good reversibility, high capacity for lithium ion insertion. V2O5-CNTs nanocomposites were synthesized by a sol-gel method, using the solvent exchange and ambient pressure drying technique. Electrochemical...
