Magnetically recoverable B,F,P-TiO2/Fe3O4 nanophotocatalyst with enhanced charge separation efficiency

As observed in Fig. 6 c, their SPS responses increase in the order of TO＜BPTO＜PTO＜BTO＜BFTO＜FTO＜FPTO＜BFPTO＜BFPTO/Fe3O4, demonstrating that B, F, or P single-doping effectively promotes the photogenerated charge separation, and B,F,P-tridoping and Fe3O4-coupling produce a synergetic effect on the photogenerated charge separation.200
