The SEM-EDX method was used to investigate the structure and morphology of organic-inorganic hybrids containing zirconium, boron and phosphorus compounds, synthesized by the sol-gel method. We started by using, for the first time together, zirconyl chloride hexa-hydrate (ZrOCl·6HO), phenyl phosphinic acid and triethyl borate as precursors and reagents, at different molar ratios. The obtained hybrids showed a very high thermal stability and are not soluble in water or in organic solvents. As a consequence, such hybrid solid materials are suitable for applications at high temperatures. The obtained hybrids have complex 3D structures and form organic-inorganic networks containing Zr-O-Zr, Zr-O-P and Zr-O-B bridges. Such organic-inorganic networks are also expected to form supramolecular structures and to have many potential applications in different fields of great interest such as catalysis, medicine, agriculture, energy storage, fuel cells, sensors, electrochemical devices and supramolecular chemistry.
采用扫描电子显微镜-能谱仪（SEM-EDX）方法研究了通过溶胶-凝胶法合成的含锆、硼和磷化合物的有机-无机杂化物的结构和形态。我们首次将六水合氧氯化锆（ZrOCl·6H₂O）、苯膦酸和硼酸三乙酯作为前驱体和试剂，以不同的摩尔比共同使用。所得到的杂化物表现出非常高的热稳定性，且不溶于水或有机溶剂。因此，这类杂化固体材料适用于高温应用。所得到的杂化物具有复杂的三维结构，并形成了包含Zr-O-Zr、Zr-O-P和Zr-O-B桥的有机-无机网络。这类有机-无机网络还预计会形成超分子结构，并在催化、医学、农业、储能、燃料电池、传感器、电化学器件和超分子化学等众多备受关注的不同领域具有许多潜在应用。
