In this article, we designed a photocatalytic cotton fabric of Fe(III)@BiVO4/cotton via thiol-ene click reaction and achieved an enhanced photocatalytic performance and excellent recyclability under visible-light irradiation. The Fe(III)@BiVO4 and cotton fabric were modified with KH570 (including C=C groups) and KH580 (including -SH groups), respectively. Then, the Fe(III)@BiVO4/KH570 and KH580/cotton reacted and connected via thiol-ene click reaction, which can effectively solve its recyclability in practical application and realize ideal all-in-one structure. The as-prepared Fe(III)@BiVO4/cotton not only exhibited an excellent photocatalytic performance in reducing Cr(VI)to Cr(III), but also showed a remarkable performance in degradation of C.I. reactive blue 19 (RB-19)
under visible-light. Meanwhile, various analysis technique were used to confirm the successful connection between Fe(III)@BiVO4 and cotton fabric via thiol-ene click reaction. Moreover, the photocatalytic mechanism was also discussed comprehensively in view of trapping experiments and ESR analysis.
