Tribocatalysis, as a new approach in environmental purification, has drawn increasing attention in the past few years. In this work, we successfully convert mechanical energy to chemical energy by BiTiO, which was synthesized by a hydrothermal method. Under magnetic stirring, electrons transfer from the surface of BiTiO to the polytetrafluoroethylene-sealed magnetic bar due to their friction. Moreover, the holes that remain on BiTiO provide oxidation properties in the process for organic matter degradation. According to a series of tests, it is noticed that the shape of the stirring bar and the material of the reaction vessel have a remarkable influence on the removal efficiency of contaminants. Simultaneously, multiple tests reveal the high stability of BiTiO. A great potential for BiTiO to control water pollutants under dark conditions during collection of ambient mechanical energy was clearly demonstrated in this study.
摩擦催化作为环境净化领域的一种新方法，在过去几年中受到了越来越多的关注。在这项工作中，我们通过水热法合成的BiTiO成功地将机械能转化为化学能。在磁力搅拌下，由于摩擦，电子从BiTiO表面转移到聚四氟乙烯密封的磁棒上。此外，留在BiTiO上的空穴在有机物降解过程中提供氧化性能。根据一系列测试，发现搅拌棒的形状和反应容器的材料对污染物的去除效率有显著影响。同时，多项测试表明BiTiO具有很高的稳定性。本研究清楚地证明了BiTiO在收集环境机械能的黑暗条件下控制水污染物方面具有巨大潜力。
