Abstract

While using hydrothermal method we obtained nanocrystal nickel molybdate hydrate (NiMoO₄). Its further calcination at 400 °C enabled us to obtain α-phase of NiMoO₄ hydrate. The modification of physical and chemical properties of prepared NiMoO₄ hydrate was being done with the aid of powerful laser radiation with the further composite formation on its basis. We have established the interconnection of vibrational modes of triclinic and monoclinic structures of nickel molybdates with corresponding bands in Raman spectra. We established that registered intensive bands with maximum 947, 870, 828, and 354 cm⁻¹ correspond to vibrational modes of МоО₄ tetrahedrons of NiMoO₄ hydrates, while intensive bands with maximum 960, 912, and 706 cm⁻¹ in α-NiMoO₄ correspond to stretching vibrational modes in Мo–О and О–Мo–О, bending modes О–Мo–О connections in MoO₆ octahedron.

摘要

在使用水热法的同时，我们获得了纳米晶钼酸镍水合物（NiMoO ₄）。其在 400 °C 下的进一步煅烧使我们能够获得 NiMoO ₄水合物的α 相。制备的NiMoO ₄水合物的物理和化学性质的改变是在强大的激光辐射的帮助下进行的，并在此基础上进一步形成复合物。我们已经建立了钼酸镍三斜和单斜结构的振动模式与拉曼光谱中相应带的相互联系。我们建立了最大的947，870，828注册的密集带，并354厘米^-1对应于МоО的振动模式_4个四面体NiMoO的₄水合物，而α-NiMoO _{4 中}最大为 960、912和 706 cm ^{-1 的}强带对应于 Мo-О 和 О-Мo-О 中的伸缩振动模式，MoO ₆八面体中的弯曲模式 О-Мo-О 连接。
