Synthesis and catalytic activity of silver- reduced graphene oxide and silver- magnetite- reduced graphene oxide nanocomposites in the reduction of 4-nitrophenol

Catalyst characterization

FTIR spectra of pure GO and Ag/rGO composites are illustrated in Fig. 1a. The FTIR spectrum of GO displayed characteristic peaks at 1052 cm⁻¹ (OH), 1218 cm⁻¹ (C–O–C), 1400 cm⁻¹ (C–OH), 1627 cm⁻¹ (C=C), 1736…
