在空气中金属纳米粒子表面极易氧化而丧失活性,有必要对金属纳米粒子的氧化机理进行深入的研究。从金属纳米粒子氧化行为、氧化膜生长动力学和分子动力学模拟3个方面综述了金属纳米粒子的氧化机理的研究现状,指出了今后研究的方向。
It is necessary to study the oxidation mechanism of metallic nanoparticles because the surface of metallic nanoparticles is easily oxidated to lose reactivity in air. The study of the oxidation mechanisra of metallic nanoparticles in recent years was reviewed synthetically from the oxidation behavior of metallic nanoparticles, the growth dynamics of oxide films and molecular dynamics simulations. In addition, the problem and future development in this research field were pointed out.
