Abstract
A series of dual-metal ferrocenyl coordination polymer microspheres (M1M2-CPMs, M1M2 = CoMn, CoCu, MnCu) were synthesized by the reaction of 1,1′-ferrocene dicarboxylic acid with mixed metal salts via solvothermal method. From SEM and TEM images, it was found that all the as-synthesized coordination polymers showed microspheres structures. The products were also characterized by X-ray photoelectron spectroscopy (XPS), fourier transform infrared (FT-IR), powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). The M1M2-CPMs showed good thermostability and remained stable up to 250 °C. These M1M2-CPMs exhibited hydrogen uptake capacity. More interestingly, through the comparison among three microspheres we found that the M1M2-CPMs with hollow structures showed better hydrogen uptake.
