采用直接沉淀合成法,在无模板剂存在下,使用聚(苯乙烯-苯乙烯基膦酸)、磷酸二氢钠作磷源合成了不同比例的新型有机聚合物-无机杂化材料聚(苯乙烯-苯乙烯基膦酸)-磷酸锌Zn(NaPO4)1-x(O3PG)x.mH2O(x=0.35~1.0,G是有机基团),用FT-IR、TG、XRD、N2吸附、SEM等手段对其进行了表征,结合实验数据提出了其可能的理想结构模型。结果表明这类新型杂化材料具有规整的层状结构,有一定的比表面及较好的热稳定性,可以作为新型的催化剂载体材料。
A new type of zinc poly(styrene-phenylvinylphosphonate)-phosphate Zn(NaPO4)1-x(O3PG)x·mH2O(x=0.35-1.0,G is organic group) in a series of stoichiometric ratios was synthesized in the absence of template agent in this paper.The phenylvinylphosphonate and sodium dihydrogen phosphate have been used as phosphorus resource.These compounds were well characterized by FT-IR,TG,XRD,N2 volumetric adsorption,SEM.The results showed that the new hybrid materials with regular layered structure,determinate surface area and thermal stability could be used as a new type of catalyst support materials.
