Figure S1. XRD pattern of the as-synthesized CoMn 2O4 product Figure S1 shows the typical XRD pattern of the as-obtained sample when Co(NO3)2·6H2O is applied during the synthetic process. Evidently, the resulting product is the CoMn2O4 (JCPDS no. 77-0471).

Figure S2. XRD pattern of XRD pattern of the product when Ni(NO3)2·6H2O was applied during the synthetic process Figure S2 shows the typical XRD pattern of the product when Ni(NO3)2·6H2O is applied during the synthetic process. Unfortunately, although some new diffraction peaks are observed, we cannot confirm which phase it is. But one thing is certain that the as-obtained sample is not the NiMn2O4 phase.

Figure S3. XRD pattern of the product when Cu(NO3)2·3H2O was applied during the synthetic process Figure S3 shows the typical XRD pattern of the product when Cu(NO3)2·3H2O is applied during the synthetic process. Obviously, when Cu(NO3)2·3H2O was used in the synthetic process, just Mn3O4 (JCPDS no. 24-0734) and Cu (04-0836) were obtained, rather than the CuMn 2O4 phase. However, it strongly verifies the existence of reduction procedure during the reaction indeed.
