Remarkable improvement of visible light photocatalysis with PANI modified core-shell mesoporous TiO2 microspheres

▶ The core-shell mesoporous structure of PANI/M-TiO2 improved the light absorption. ▶ The heterojunction between TiO2 and PANI facilitated the separation of carriers. ▶ Enhanced photocatalysis was achieved via PANI modified core-shell mesoporous TiO2.
