Zusammenfassung:The invention relates to the technical field of preparation of doped nanocrystal catalysts, in particular to a blocky Ag/TiO2 composite material as well as a preparation method and application thereof. Comprising the following steps: adding P25 nano TiO2 particles into a KOH solution, and slowly stirring at room temperature to obtain a mixture; transferring the obtained mixture into a polytetrafluoroethylene hydrothermal reaction kettle for hydrothermal reaction to obtain a reaction solid; and separating, washing and drying the obtained reaction solid to obtain the blocky TiO2 nano material. And preparing the blocky Ag/TiO2 composite material by taking the blocky TiO2 nano material as a raw material through a gel method. The blocky TiO2 nano material is successfully prepared by utilizing an improved hydrothermal method, the blocky Ag/TiO2 composite material is successfully prepared by utilizing an improved sol-gel method, controllable synthesis of a silver-doped titanium dioxide catalyst is realized, and the
