The phases and crystal structure of the materials were investigated by x-ray diffraction XRD with a Cu Kα radiation λ 0154 nm at a scanning rate of 4 min 1 in the 2. α-Fe2O3 nanoparticles were synthesized by facile hydrothermal process at low-temperature and used as efficient anode material for the fabrication of lithium ion battery. And the as-obtained α-Fe2O3 nanopolyhedra exhibits ultrahigh reversible capacity and excellent capacity retention over 20 cycles. Namely there are two entirely different proposals on this issue viz. α-Fe 2 O 3 nanotubes are exceptional one-dimensional transition metal oxide materials with low density large surface area promising electrochemical and photoelectrochemical properties which are widely investigated in lithium-ion batteries photoelectrochemical devices gas sensors and catalysis. The bacterial cellulose with excellent mechanical stability and film-forming feature not only benefits the formation of a stable membrane to avoid the separation and recycling problems but also helps disperse and accommodate α-Fe 2 O 3 nanodisks and thus enhances the visible light absorption performances leading to an excellent PMS-based visible light degradation efficiency under both.
