“…A lot of research demonstrates that coupling with conjugated polymers (CPs) can substantially heighten the photocatalytic activity of semiconductors. − Generally, CPs can increase the photocatalysis of semiconductors due to the following positive cooperative effects: (i) they can be activated by visible-light to provide additional h + and e – , due to their exceptionally strong absorption of visible-light, and (ii) they can promote the separation and transfer of h + and e – , due to their capability of forming heterojunctions with semiconductors and fair charge-transporting ability. − But, most CPs explored in the past are difficult to mass produce and are not cost-effective polythiophene, polyimide, polyaniline, polypyrrole, etc., which are unsuitable for large-scale industrial applications. − …”
