A novel solid state reaction method has been followed to prepare LiCoO 2 (LCO) using micro porous filter paper as scaffolds. FT-IR spectroscopy confirms the vibration spectrum for the identification of CoO 6 as well as LCO. XRD diffraction analyses confirmed the formation rhombohedral crystal system of the prepared LCO materials with R-3m space group. The sharp XRD diffractogram of filter paper scaffold LCO demonstrate its crystallinity and purity. The presence of high intensity (003) plane, formation of Co–O–Co linkage with (104) plane and splitting of (006)/(012); (108)/(110) planes confirm layered structure of the prepared LCO. FESEM demonstrate that the presence of micropores in the cellulose backbone of filter played significant role for the solid state reaction and can be used as a scaffold to change the morphology of LCO in the microstructural aspect. UV-visible spectroscopy study reveals that the band gap energy of filter papers assisted LCO are less ...

以微孔滤纸为支架制备LiCoO 2的新型固态反应路线

遵循一种新型的固态反应方法，以微孔滤纸为支架制备LiCoO 2（LCO）。FT-IR光谱证实了用于识别CoO 6和LCO的振动光谱。XRD衍射分析证实了所制备的具有R-3m空间群的LCO材料的形成菱面体晶体体系。滤纸支架LCO的XRD衍射图表明其结晶度和纯度。高强度（003）平面的存在，与（104）平面的Co-O-Co键的形成和（006）/（012）的分裂；（108）/（110）平面确认了所制备LCO的分层结构。FESEM表明，过滤器的纤维素主链中微孔的存在对固态反应起着重要作用，并且可以在微观结构方面用作改变LCO形态的支架。紫外可见光谱研究表明，滤纸辅助LCO的带隙能量较小。
