摘要
文章通过了解国内外水热法的研究,查阅纳米功能材料的各种制备方法,详细介绍了水热法的基本情况,包括定义、原理、分类、适用条件等,并将水热法与其他制备方法进行比较。文章还简单描述了水热法制备光催化材料的研究进展,并对水热法的未来进行了展望。经过对比发现:水热法与其余方法比较而言具有可制备粉体种类多、可直接获得结晶良好的粉体、晶粒线度适度可调、低耗能高产出、工艺较简单等优点;同时也有着反应周期长、现阶段通常用于制备氧化物粉体、对生产设备的依赖性比较强的缺点。但科学家们也在不断地发展改良,其中溶剂热法、超临界水热法、微波水热法就是水热法的改良与发展。最后从多个不同的方面介绍了现阶段水热法制备光催化材料的研究进展,这些都充分说明了水热法的发展潜力。
In this work,the progress of hydrothermal methods is introduced,with referring various preparation methods of nano-functional materials.The definition,principle,classification,applicable conditions of hydrothermal methods are introduced in detail.Meanwhile,the research progress of hydrothermal method for preparing photocatalytic materials is introduced.Compared with other preparation methods,it is found that the hydrothermal method can directly obtain a well-crystallized powder,while the grain size is moderately adjustable.Besides,it is low energy consumption with high output,various types of powders can be prepared,the process is relatively simple.It also has the shortcomings such as long reaction cycle,generally limited to prepare oxide powders,and strong dependence on the equipment.However,scientists are constantly developing and improving this method,and some developments has been achieved,including solvents thermal method,supercritical hydrothermal method,and microwave hydrothermal method.Finally,the research progress in the preparation of photocatalytic materials by hydrothermal methods are introduced here,which fully illustrates the development potential of hydrothermal methods.
