Three-dimensional reduced graphene oxide aerogel stabilizes molybdenum trioxide with enhanced photocatalytic activity for dye degradation.

ABSTRACT: By using three-dimensional reduced graphene oxide (rGO) aerogel as a carrier for molybdenum trioxide (MoO₃), a series of rGO-MoO₃ aerogels were synthesized by a self-assembly process. The results indicated that the as-prepared rGO-MoO₃ aerogel had very low density and good mechanical properties, and would not deform under more than 1000 times its own pressure. The rGO-MoO₃ aerogel showed more than 90% degradation efficiency for MB within 120 min. After six cycles of recycling, the degradation rate of MB only decreased by 1.6%. As supported by the electron paramagnetic resonance (EPR) measurements, the presence of the rGO aerogel enhanced electron conduction, prolonged carrier lifetime and inhibited electron and hole recombination, thus improving
