Fabrication of Active Z-Scheme Sr₂MgSi₂O₇: Eu²⁺, Dy³⁺/COF Photocatalyst for Round-the-Clock Efficient Removal of Total Cr.

ABSTRACT: Photoreduction is recognized as a desirable treatment method for hexavalent chromium (Cr(VI)). However, it has been limited by the intermittent solar flux and limited light absorption. In this work, a novel Z-scheme photocatalyst combining a covalent organic framework (COF) with Eu²⁺, Dy³⁺ co-doped Sr₂MgSi₂O₇ (Sr₂MgSi₂O₇:Eu²⁺, Dy³⁺) is synthesized, which shows the high spectral conversion efficiency and works efficiently in both light irradiation and dark for Cr(VI) reduction. Sr₂MgSi₂O₇:Eu²⁺, Dy³⁺ serves as both an electron transfer station and active sites for COF molecule activation, thus resulting in 100% photoreduction of
