The results of the dissertation were concluded as follows:(1) It is essential to deposit a basic additive on the Mo-based catalysts for the synthesis of CH_3SH. The potassium-doped Mo-based catalysts exhibit the highest activity than that of the catalysts doped with the otherⅠA andⅡA group basic promoters. H_2-TPR and LRS characterizations suggest that the addition of a base leads to the transformation of octahedrally coordinated Mo to tetrahedrally coordinated Mo, thus leads to the split of low temperature reduction peaks. The interaction between the basic components and Mo lead to the formation of B-Mo interface phase, which are closely correlated with the formation of CH_3SH.(2) It has been found that Fe, Co, Ni and Te have evident promoting effects for the K-Mo/SiO_2 catalysts.
主要结果归纳如下:(1)在Mo基催化剂中,必须添加碱才具有可观的合成甲硫醇活性,在IA和IIA族元素中,K是最佳的碱促进剂,当K/Mo摩尔比为2,前驱体为K_2CO_3,采用共浸法制备的K-Mo催化剂活性最高。H_2-TPR和LRS表征显示,碱的加入导致表面八面体钼氧物种向四面体转化,催化剂的低温还原峰发生分裂,碱助剂与钼之间存在强相互作用形成了B-Mo"界面相",该物种与合成甲硫醇密切相关。

B.C.. The root of the word coined for this, esthlos , signifies one who is, who possesses reality, who is actual, who is true; then, with a subjective turn, the true as the truthful: in this phase of conceptual transformation it becomes a slogan and catchword of the nobility and passes over entirely into the sense of "noble," as distinct from the lying common man, which is what Theognis takes him to be and how he describes him—until finally, after the decline of the nobility, the word is left to designate nobility of soul and becomes as it were ripe and sweet.
用来表达这个意思的词:esthlos的词根意味着一个人只要是存在的,现实的,真切的,他就是真正的人;而后,经过一个主观的转变,真正就变成了真实:在概念转化的这个阶段,真实成了贵族的口头禅,而且彻底地包含在"贵族的"词义里,以示和被蒂奥哥尼斯认之为并描述为不诚实的下等人相区别——一直到贵族没落以后,该词才最终被保留下来用于标志精神贵族,与此同时该词也变熟、变甜了。

Electroless Co-Ni-P thin film as-deposited was amorphous possessing smooth surface. The film was crystallized after heat treatment at 300℃ for 1 hour, and the surface of film was composed of "taper humps". When the film was heated, phase of Co2P deposited from the solid solution and allotropic transformation took place from hexagonal close-packed system to face-centred cubic lattice.
