| 中文摘要 | self-assembled pompon-like beta-ni(oh)(2) microspheres with hollow structured interiors were synthesized via a simple hydrothermal method with the assistance of sodium poly(4-styrenesulfonate) (pss). the structural, morphological and electrochemical properties of the microspheres have been examined in detail. the crystalline "beta" phase of ni(oh)(2) is confirmed by the x-ray diffraction (xrd) analysis. morphological characterization by sem and tem reveals that beta-ni(oh)(2) is composed of well dispersed pompon-like spheres with hollow structured interiors. moreover, the morphology and size of beta-ni(oh)(2) can be tuned by altering the pss concentration. systematic time-dependent experiments were carried out and a possible formation mechanism was proposed on the basis of ostwald ripening. the electrochemical properties of the as-prepared microspheres were studied by means of cyclic voltammetry (cv), chronopotentiometry (cp) and galvanostatic charge discharge tests. it is found that the as-prepared beta-ni(oh)(2) microspheres show excellent capacitance behavior of 1028.5 f/g at a charge/discharge current density of 2.22 a/g and an almost 100% coulombic efficiency after 1000 cycles at a current density of 3.7 a/g. these results suggest this beta-ni(oh)(2) hollow microspheres is a highly promising candidate for the supercapacitor electrodes.
