The honeycomb-like Eu3+, Fe3+ doping bismuth molybdate photocatalyst with enhanced performance prepared by a citric acid complex process

The Eu3+,Fe3+ doped honeycomb-like bismuth molybdate photocatalysts have been prepared through a citric acid complex process. The samples were characterized by XRD, XPS, SEM, TEM, FT-IR, UV-vis and PL. It was found that Eu3+ and Fe3+ codoping bismuth molybdate exhibited the highest activity with the degradation rate of RhB being 94.1% in 50 min and the photocatalytic performance of Eu-Fe-BMO was not simply the sum of Eu-BMO and Fe-BMO two individual catalysts. The Eu-Fe-BMO sample indicates excellent stability and reusability.
