An Efficient Catalyst for Restoration of Large Volume Effluent Containing 4-Nitrophenol at Room Temperature

Abstract

An efficient and stable catalyst was prepared utilizing reduced graphene oxide, Ag nanoparticles and melamine sponge for the restoration of large volume effluent containing 4-nitrophenol at room temperature. And the as-prepared sample is suitable for continuous flow system. Almost 99% 4-nitrophenol ([Formula: see text][Formula: see text]mol[Formula: see text]L[Formula: see text], 100[Formula: see text]mL) can be removed within 4[Formula: see text]min in the presence of the aforementioned sample. Moreover, it also exhibits remarkable stability in continuous flow system. This may offer a new route to the fabrication of efficient flowing catalytic system.
