以K0.81Li0.27Ti1.73O4为前驱物,通过水热方法合成出一种新型多晶格化合物[Ni(OH)1.115(H2O)0.885]1.2.2(Ti1.73O4).1.65H2O.应用XRD,IR,TG-DTA和TEM等测试方法对该化合物进行了表征.结果表明,在该化合物中,TiO2层和Ni(OH)2层沿c方向交替堆积,分别形成3个次级晶格.其中TiO2次级晶格属于正交晶系,其可能的空间群是Pmmm,晶格参数a=0.3875 nm,b=0.2976 nm,c=2.288 nm和α=β=γ=90°.另外2个Ni(OH)2次级晶格具有相同的大小和对称性,晶格参数a=b=0.3140 nm,c=2.288 nm,α=β=90°,γ=120°.TiO2次级晶格和Ni(OH)2次级晶格在ab平面二维方向上不匹配.
A new type of multi-lattice compound [Ni (OH) 1.115 (H2O) 0.885] 1.2.2 (Ti1.73O4) 1.65H2O was synthesized by hydrothermal method using K0.81Li0.27Ti1.73O4 as precursor. , IR, TG-DTA and TEM.The results showed that TiO2 and Ni (OH) 2 layers were alternately deposited along c direction to form three secondary lattices respectively. Among them, the secondary lattice of TiO2 belongs to the orthorhombic system, the possible space group is Pmmm, the lattice parameters a = 0.3875 nm, b = 0.2976 nm, c = 2.288 nm and α = β = γ = The secondary lattice of Ni (OH) 2 has the same size and symmetry. The lattice parameters a = b = 0.3140 nm, c = 2.288 nm, α = β = 90 ° and γ = The secondary lattice of Ni (OH) 2 does not match in the two-dimensional direction of the ab plane.
