原始语种摘要: Abstract(#br)Several MnO 2 nanomaterials synthesized at autoclave temperatures ranging from 130 to 210°C were characterized and investigated for sulfamethoxazole (SMX) oxidative degradation in aqueous solution. The pure single-crystal α-MnO 2 nanorods prepared at 150°C showed the highest SMX degradation efficiency. We concluded that the crystallographic structure and the surface species of MnO 2 were more important than BET surface area and crystallinity in influencing the activity in SMX oxidative degradation. The high degradation efficiency of α-MnO 2 nanorods resulted from a (2×2) tunnel structure, rich surface adsorbed oxygen and high oxygen mobility. The degradation efficiency of α-MnO 2 nanorods was also...
