The titanium niobium (HTiNbO5) acid doped graphene based hydrogel can be synthesized in the presence of organic amine by using the hydrothermal method. This paper analyzes the effects caused by the types of organic amine and the content of titanic-niobic acid on the elements and photocatalytic property of graphene composite hydrogel. In the end, this paper com-pares their photocatalytic properties of methyl orange among the graphene hydrogel, the titanium niobate nanosheet and the ti-tanium niobium (HTiNbO5) acid doped graphene hydrogel. The result shows that the titanium niobium doped graphene hydrogel could eliminate methyl orange under the photocatalytic effects. The material has the following features, including easy carry, easy recycling, good adsorption and, excellent photocatalytic property.%利用水热合成方法，在有机胺存在时，合成了钛铌酸掺杂的石墨烯基复合水凝胶。分别考察了有机胺的种类和钛铌酸的含量对制备的石墨烯基复合水凝胶的形貌和光催化性能的影响。最终分别比较了石墨烯水凝胶、钛铌酸纳米片和钛铌酸掺杂石墨烯基复合水凝胶对甲基橙在紫外-可见光下的光催化效果。结果表明，钛铌酸掺杂的石墨烯基复合水凝胶在紫外-可见光下对甲基橙具有更好的消除效果。该材料具有易携带、易回收、良好的吸附和优异的光催化效果于一体的特点。
