盐类和氧化物等活性组分在一定条件下,可在高比表面载体上自发分散。研究这些过程对多相催化剂、吸附剂的制备过程理解和控制无疑是重要的。这类分散过程已被系统地研究,并提出了单层分散模型,对CuCl_2/γ-Al_2O_3、HgCl_2/活性炭等多种体系,测定了单层分散阈值。表面化学习惯上理解为就是二维的化学。早在1931年Tayor就指出表面是不均匀的,但这种不均匀性是作为对理想二维表面的修正而引入的,如TLK模型。表面科学的这些基本概念其数学基础是欧基里德几何学,其物理背景是晶体结构,不规则性就是指晶体结
Under certain conditions, active components such as salts and oxides can be spontaneously dispersed on high surface area carriers. It is undoubtedly important to study these processes for understanding and controlling the preparation of heterogeneous catalysts and adsorbents. This kind of dispersion process has been studied systematically and a single-layer dispersion model has been proposed. The monolayer dispersion threshold for CuCl 2 / γ-Al 2 O 3, HgCl 2 / activated carbon and other systems has been determined. Surface chemistry is conventionally understood as two-dimensional chemistry. Tayor pointed out that the surface was uneven as early as 1931, but this inhomogeneity was introduced as a modification of the ideal two-dimensional surface, such as the TLK model. The mathematical basis of these basic concepts of surface science is the Euclidean geometry, the physical background of which is the crystal structure, the irregularity refers to the crystal junction
