We herein report on the synthesis by a facile sol-gel method without templates for preparing rutile RuTiO (x = 0.16; 0.07; 0.01) nanobelts with exposed (001) facets. The rutile nanobelts with exposure (001) facets, favor the separation photogenerated electron-hole pairs and inhibit the recombination of the electron-hole pairs resulting in the increase of the number of main superoxide and hydroxyl radicals. The photocatalytic properties of the rutile RuTiO nanobelts were evaluated by discoloring of MB (methylene blue) dye under sunlight irradiation at an intensity of 40000 lx. It was also done a thorough interface analysis to determine the band energy.

我们在此报告一种简便的无模板溶胶-凝胶法合成具有暴露（001）面的金红石型RuTiO（x = 0.16；0.07；0.01）纳米带。具有暴露（001）面的金红石型纳米带有利于光生电子-空穴对的分离，并抑制电子-空穴对的复合，从而导致主要超氧自由基和羟基自由基数量的增加。通过在40000 lx强度的阳光照射下使亚甲基蓝（MB）染料褪色来评估金红石型RuTiO纳米带的光催化性能。还进行了全面的界面分析以确定能带能量。
