Catalytic reduction of methylene blue and rhodamine B using Ce-MOF-derived CeO2 catalyst

In this study, a CeO2 catalyst was derived from a Ce-based metal-organic framework (Ce-MOF) via an annealing process. Various analytical techniques, including XPS, XRD, SEM/EDX, and HR-TEM, were used to characterize the Ce-MOF-derived CeO2 nanoparticles. The as-synthesized Ce-MOF and Ce-MOF-derived CeO2 catalysts were used for the reduction of methylene blue (MB) and rhodamine B (Rh B) in the presence of NaBH4. Compared with Ce-MOF, the CeO2 catalyst exhibited a 90 % reduction of MB/RhB within 6 and 8 min, respectively.

Automated summary

A CeO2 catalyst was obtained through annealing of a Ce-based metal-organic framework (Ce-MOF), and characterized using various analytical techniques. The CeO2 catalyst showed a 90% reduction of MB/RhB in 6 and 8 minutes, respectively, compared to Ce-MOF, when NaBH4 was present.
