A series of small and well defined cobalt nanoparticles were synthesized by the chemical reduction of cobalt salts in water using NaBH4 as a reducing agent and using various polymeric stabilizers. The obtained nanocatalysts of similar mean diameters (ca. 2.6 nm) were fully characterized and tested in the aqueous phase Fischer-Tropsch Synthesis (AFTS). Interestingly, the nature and structure of the stabilizers used during the synthesis of the CoNPs affected the reduction degree of cobalt and the B-doping of these NPs and consequently, influenced the performance of these nanocatalysts in AFTS.
通过使用硼氢化钠（NaBH4）作为还原剂并使用各种聚合物稳定剂，在水中对钴盐进行化学还原，合成了一系列尺寸小且定义明确的钴纳米颗粒。所获得的平均直径相似（约2.6纳米）的纳米催化剂经过了全面表征，并在水相费托合成（AFTS）中进行了测试。有趣的是，在钴纳米颗粒合成过程中使用的稳定剂的性质和结构影响了钴的还原程度以及这些纳米颗粒的硼掺杂，因此，影响了这些纳米催化剂在水相费托合成中的性能。
