**5. Morphology Regulation of the Composite Photocatalysts**

Apart from the intrinsic characteristics of semiconductors, the corresponding catalysts with different morphologies may result in different photocatalytic activities and different application processes [89]. Recently, morphology modification of the photocatalysts have attracted more and more attention owing to further improvements in their application performance, not only for the photocatalytic performance but also for the application techniques. With this in mind, in this section we will briefly summarize the recent achievements of the composite photocatalysts with different morphologies of 0D, 1D, 2D, and 3D materials.
