Titanium based MOF materials NH₂-MIL-125 was synthesized through solvothermal method. By increasing the concentration of the reactants, the morphology of NH₂-MIL-125 can be controlled from circular plate to special polyhedron. Meanwhile, the polyhedron can be modulated from octahedron to rhombic dodecahedron through changing the titanium ester of the reactants from tetraethyl titanate to tetrabutyl titanate. This is the first time to obtain NH₂-MIL-125 with rhombic dodecahedron morphology. The test of acetic acid as additive on morphology changes shows that the adsorption of additives on special facets shows a more significant impact on the morphology formation. The morphology control of NH₂-MIL-125 based on the modulation of the type of titanium ester, reactants concentration, and the added acetic acid concentration were detailed exhibited and explained.

通过溶剂热法合成了钛基MOF材料NH ₂ -MIL-125。通过增加反应物的浓度，可以控制NH ₂ -MIL-125的形态，从圆形板到特殊的多面体。同时，通过将反应物的钛酸酯从钛酸四乙酯改变为钛酸四丁酯，可以将多面体从八面体调制为菱形十二面体。这是第一次获得具有菱形十二面体形态的NH ₂ -MIL-125。醋酸作为添加剂对形态变化的测试表明，添加剂在特殊面上的吸附对形态的形成有较大的影响。NH ₂的形态控制详细介绍并说明了基于钛酸酯类型，反应物浓度和添加乙酸浓度的调节的-MIL-125。
