Solvothermal Route

Porous cobalt (Co) microspheres were successfully synthesized via a facile surfactant-free solvothermal route. These microspheres have an average diameter of about 2 µm, assembled by many primary Co nanosheets. A possible formation mechanism of porous Co microspheres is discussed. The magnetic hysteresis loop shows a ferromagnetic feature of porous Co microspheres and the saturation magnetization (Ms) and coercivity (Hc) are 115.3 J/T·kg and 6.883 kA/m, respectively.

Experimental Parameters

Hierarchical calcium carbonate spheres composed of nanoparticles has been successfully synthesized via a solvothermal process. The structures are fabricated by the reaction of Ca (CH3COO)2with (CO(NH2)2) at 110 °C in diethylene glycolwater mixed solvents in the presence of polyvinylpyrrolidone. The as-prepared products were characterized by field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD). The characterization results revealed that the average diameter of the hierarchical calcium carbonate spheres is about 5 μm, and the size of the nanoparticals range from 50 to 100 nm. In addition, a small amount of bundle-like aragonite calcium carbonate is also obtained in the experimental parameters.
