Abstract：As a fascinating and widely used polymer, polyimide (PI) has become a new research hotspot and drawn broad interdisciplinary attention as a visible-light-responsive photocatalyst. This is due to its appealing electronic band structure and high physicochemical stability. This critical review summarizes a panorama of the latest progress related to the design and construction of PI and PI based composite photocatalyst, including (1) graphitic carbon nitride (g-C3N4) based photocatalytic structure in polyimide, (2) nanoarchitecture design of bare polyimide and its photocatalytic ability, (3) modification of PI and well-matched energy levels of another semiconductor to form heterojunction nanostructure. In the review, there will be also theoretically discussed the band structures, electronic properties, optical absorption, and interfacial charge transfer in PI-based heterostructures nanohybrids.It is anticipated that this review can stimulate a new research doorway to facilitate the next generation of PI based photocatalysts with ameliorated performances by harnessing the outstanding structural, electronic, and optical properties
