Hierarchical Co9S8@Carbon Hollow Microspheres as an Anode for Sodium Ion Batteries with Ultralong Cycling Stability

ACS Sustainable Chemistry and Engineering, 2019
Herein, hierarchical Co9S8@carbon hollow microspheres (Co9S8@CHSs) were designed and facilely prepared via a simple solvothermal approach, following a thermal treatment process. The surfaces of the hierarchical Co9S8 hollow microspheres are homogeneously

Structure of hollow polystyrene microspheres: An SEM study

Journal of Microencapsulation, 1989
Hollow polystyrene microspheres have been prepared by a modified interfacial polymer deposition technique. The hollow microspheres were characterized using scanning electron microscopy. The effects of polymer concentration and the quantity of the internal phase material (methanol) used on the microsphere size and their wall thickness were studied ...

Hydrothermal synthesis of SnO2 hollow microspheres

Materials Letters, 2005
Abstract SnO 2 hollow microspheres have been synthesized by a hydrothermal method. X-ray powder diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM) were used to characterize such hollow microspheres. SEM image shows that SnO 2 microspheres with diameters of 0.5–1 μm are composed of SnO 2 nanoparticles with about 15 nm in ...

Hollow Ni/C microspheres derived from Ni-metal organic framework for electromagnetic wave absorption

, 2020
Hollow nickel/carbon (Ni/C) microsphere was synthesized by in situ pyrolysis of the Ni-based trimellitic acid framework (Ni-MOF) at argon atmosphere. The morphology of Ni-MOF precursor can be easily controlled by adjusting the volume ratio of DMF and H2O
