In this work, we demonstrated a completely new, simple and effective strategy for preparing catalysts by using β-MnO 2 nanotubes as the supporting materials, and the Pd nanoparticles were coated onto β-MnO 2 nanotubes through a simple reductive process firstly. The as-prepared materials were characterized by field emission scanning electron microscopy (FESEM), transmission electron...
Aluminum-doped spinel-type LiMn 2 O 4 cathode active materials have been synthesized by a microwave-assisted sol–gel method. The influence of synthesis conditions on the structural and electrochemical properties of LiAl 0.1 Mn 1.9 O 4 was investigated by thermo-gravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), and charge/discharge...
