Conjugated microporous polymer with matched energy band structure as photocatalyst for simultaneous removal of heavy metal ion and organic pollutant

“…[9][10][11][12][13][14] Traditionally, photocatalysis has utilized semiconductor materials (TiO 2 , ZnO) as catalysts; these materials exhibit several limitations such as a low sunlight utilization rate and high photogenerated carrier recombination rate, which lead to unsatisfactory photocatalytic efficiency. [15][16][17] In addition, photocatalysts that can simultaneously reduce heavy metals and oxidize to degrade organic pollutants are still very scarce, 18 because it is difficult to meet the conduction and valence band requirements for photocatalysis at the same time. [19][20][21][22] Therefore, the development of suitable photocatalysts that can deal with heavy metal/organic combined pollutants is still very challenging.…”
