The invention discloses a cobalt-manganese-based catalyst for cyclohexene hydroformylation reaction and preparation and application thereof. The preparation method comprises the following steps: carrying out a heating reaction on a dispersion liquid of a nanoscale cobalt-based raw material and cyclopentadienyl manganese tricarbonyl and/or a derivative thereof under a protective atmosphere to obtain a solid-liquid mixture, namely the cobalt-manganese-based catalyst. The preparation method provided by the invention is simple in process, stable in reaction performance and high in yield, and the obtained catalyst is high in catalytic activity, low in preparation cost and high in cyclic utilization rate. 本发明公开了环己烯氢甲酰化反应用钴-锰基催化剂及其制备与应用。其中所述制备方法包括：将纳米级钴基原料的分散液与环戊二烯三羰基锰和/或其衍生物在保护气氛下加热反应，所得固液混合物即为所述钴-锰基催化剂。本发明提供的制备方法过程简单、反应性能稳定、收率高，所得催化剂催化活性高、制备成本低、循环利用率高。
