A series of solid solutions in the PdTe–PdBi system with general formula [Formula: see text]Bix ([Formula: see text], 0.5, 0.67) with the structure based on the NiAs type were synthesized by a high-temperature ampoule technique. These compounds, along with their parent binaries, PdTe and PdBi, were tested as promoters for the standard Co/Al2O3 catalytic system in the Fischer–Tropsch synthesis. It is shown that the addition of PdTe and [Formula: see text]Bix to the standard catalyst increases both yield and selectivity with respect to the liquid phase. At the same time, the addition of PdBi does not only improve catalytic activity, but also slightly inhibits it. Another positive effect of the PdTe and [Formula: see text]Bix addition is the shift in the conversion products toward the diesel and wax fractions. Chemical bonding analysis in orbital and direct space indicates that the addition of Bi to PdTe might increase the localized bonding.

富金属碲化物 PdTe1−xBix 作为功能材料：费托合成和键合分析中的催化行为

PdTe-PdBi体系中的一系列固溶体具有通式[公式：见正文]BiX([公式：见正文], 0.5, 0.67) 采用高温安瓿技术合成NiAs型结构。这些化合物及其母体二元 PdTe 和 PdBi 作为标准 Co/Al 的促进剂进行了测试2○3费托合成中的催化体系。结果表明，添加 PdTe 和 [公式：见正文]BiX与标准催化剂相比，增加了液相的产率和选择性。同时，PdBi的加入不仅提高了催化活性，而且对催化活性有轻微抑制作用。PdTe 和 [公式：见正文]Bi 的另一个积极作用X另外是转化产物向柴油和蜡馏分的转变。轨道和直接空间中的化学键合分析表明，在 PdTe 中添加 Bi 可能会增加局部键合。
