Summary:The invention provides a method for preparation of one-dimensional cobalt oxalate by rapid precipitation. The method has the excellent characteristics of high efficiency, rapidity, simplicity and thelike in material preparation, overcomes the huge challenge of regulating a one-dimensional nano-material caused by quick crystallization of precipitation reaction, the one-dimensional nano-material CoC2O4 is prepared, and sodium binoxalate (NaHC2O4) is adopted as the precipitant to precipitate the target material quickly. NaHC2O4 has low dissociation coefficient, and can slowly release C2O4<2-> ions to balance the growth speed and diffusion speed of the material, so that the material can grow in a one-dimensional direction in the growth process. The invention provides a morphology and phase regulation method of a CoC2O4 nanorod with excellent performance. The method has the advantages of low cost, fast reaction rate, mild and easily-controllable reaction, energy conservation and environmental protection, high prod
