Synergy of Photocatalysis and Adsorption for Simultaneous Removal of Hexavalent Chromium and Methylene Blue by g-C₃N₄/BiFeO₃/Carbon Nanotubes Ternary Composites.

ABSTRACT: A novel graphite-phase carbon nitride (g-C₃N₄)/bismuth ferrite (BiFeO₃)/carbon nanotubes (CNTs) ternary magnetic composite (CNBT) was prepared by a hydrothermal synthesis. Using this material, Cr(VI) and methylene blue (MB) were removed from wastewater through synergistic adsorption and photocatalysis. The effects of pH, time, and pollutant concentration on the photocatalytic performance of CNBT, as well as possible interactions between Cr(VI) and MB species were analyzed. The obtained results showed that CNTs could effectively reduce the recombination rate of electron-hole pairs during the photocatalytic reaction of the g-C₃N₄/BiFeO₃ composite, thereby improving its photocatalytic performance, while the presence of MB incre
