The effect of oxidative treatments on the depostion of cobalt nanocrystals (Co-NC) onto a support and subsequent ligand removal was investigated. Deposition of ε-cobalt NC led to extensive clustering of NC and low Fischer-Tropsch synthesis activity. Low-temperature oxidation of ε-cobalt NC resulted in a very uniform CoO-NC distribution and high activity whereas high-temperature oxidation to CoO led to less uniform NC distributions and lower activity.
研究了氧化处理对钴纳米晶体（Co-NC）在载体上的沉积以及随后配体去除的影响。ε-钴纳米晶体的沉积导致纳米晶体大量聚集且费托合成活性较低。ε-钴纳米晶体的低温氧化导致CoO-NC分布非常均匀且活性较高，而高温氧化生成CoO则导致纳米晶体分布较不均匀且活性较低。
