Oxygen vacancy-induced donor–acceptor-conjugated microporous poly(triphenylamine–benzothiadiazole)/TiO2 as a Z-scheme heterojunction photocatalyst towards a visible-light-driven degradation of bisphenol A

A Z-scheme TPABT/TiO₂ heterostructure induced by oxygen vacancies exhibited high photocatalytic performance for the degradation of bisphenol A under visible light irradiation.
