2018年7月5日 · 如 图1 所示，1T 是 a trigonal antiprismatic 结构，trigonal 是三方的意思，但这里的概念有点乱不管了，antiprismatic 表示它不是镜像的。 观察同一个Mo原子连接的6个S原子，上下两个"3个S原子组成的三角形"方向相同就是 prismatic（2H），相反就是 antiprismatic（1T）。

催化领域 作为典型的过渡金属二卤化物，MoS2也可划分为 半导体（SEMI）相和金属（MET）相， 根据Mo原子的配位和氧化态形式，其物理/化学性质与相结构密切相关。 2H-MoS2为半导体相，其带隙随层数的变化在1.2-1.9 eV范围内变化，层数较少的2H-MoS2具有明显的光学 ...

2025年2月7日 · Herein, we propose a strategy to modulate 1 T phase MoS 2 with In-O doping and lattice-grafting of Ru. The atomically doped p-block In-O can effectively reduce the distribution of vertical...
