Abstract: This paper introduces the material systems of photocatalytic coatings/films,including oxides,sulfides,nitrides,phosphides and its surface modification,and emerging material system.The preparation processes for photocatalytic coatings/films include liquid phase method,gas phase method and electrochemical method.And it points out the pros and cons of each process,and describes the influence of preparation process on the photocatalytic performance of the film.Some special micro-nano structures (core-shell and hollow structures,mesoporous structures,carbon-coated structures) of photocatalytic coating/film materials and their structural control methods are reviewed.The existing problems and future development trend for photocatalytic coating/thin film materials in preparation process,structure control and application are summarized and prospected.Through the study and design on the preparation process and material system,the light utilization rate is improved,and the structure and performance of the photocatalytic film are controlled,and controllable synthesis can also be achieved.It is predicted that photocatalytic coating/film materials will develop towards sustainable industrialization in the future.
