Dispersed Ag₂O/Ag on CNT-Graphene Composite: An Implication for Magnificent Photoreduction and Energy Storage Applications.

ABSTRACT: A simple hydrothermal route assisted by a triblock copolymer was used to synthesize Ag₂O/Ag nanoparticles on a robotic support consists of functionalized MWCNTs and graphene composite (Ag₂O/Ag/CNT-graphene). The composites together with the individual analog of Ag/CNT and Ag/graphene were characterized by means of XRD, TEM-SAED, N₂ sorptiometry, Raman, FTIR, UV-Vis, and photoluminescence spectroscopy. These nanomaterials were then tested for the catalytic reduction of 4-nitrophenol (4-NP) to the technologically beneficial 4-aminophenol (4-AP). The Ag₂O@Ag@CNT-graphene composite calcined at 400°C has shown fascinating reduction performances for 4-NP either in the dark (k = 0.014 s^-1) or under visible light illumination (k
