摘要： 通过室温固相反应合成了Ni2P2S6层状结构材料,并经XRD和Raman光谱进行了表征.与传统的高温固相反应法相比较,该法具有反应速度快、能耗低、可得均相产物的优点.TG-DTA研究表明,Ni2P2S6在空气中热氧化的终产物为Ni2P2O7,中间态可能是Ni2P2O6亚稳相.

关键词: Ni2P2S6, 层状结构, 室温固相反应

Abstract: Results of XRD and Raman spectra show the successful preparation of lamellar structural materials Ni2P2S6by a new synthetic route room temperature solid state reaction. Compared with the traditional high temperature solid state reaction, the preparation method adopted here has the following advantages: fast reaction rate, low energy cost, high homogeneity of final products and the facility of preparation in quantity. Study of TG-DTA shows the final product Ni2P2O7and the existence of an intermediate metastable Ni2P2O6phase of Ni2P2S6thermo-oxidation in air.

Key words: Ni2P2S6, Lamellar structure, Room temperature solid state reaction
