The photocatalytic reduction of aqueous Cr(VI) to Cr(Ⅲ) was preliminarily studied using porous g-C₃N₄ as a photocatalyst under acidic conditions. The observed synergistic photocatalytic effect of porous g-C₃N₄ on a Cr(VI)/4-chlorophenol (4-CP) composite pollution system was further studied under different pH conditions. Compared with single-component photocatalytic systems for Cr(VI) reduction or 4-CP degradation, the Cr(VI) reduction efficiency and 4-CP degradation efficiency were simultaneously improved in the Cr(VI)/4-CP composite pollution system. The synergistic photo-catalytic effect in the Cr(VI)/4-CP composite pollution system can be attributed to the accelerated redox reaction between dichromate and 4-CP by electron transfer with porous g-C₃N₄.
