Figure 3From: Metal ion-directed solution-phase tailoring: from large-area graphene oxide into nanoscale piecesUV-vis absorption and FTIR spectra of nanoscale GO. (a) UV-vis change with reacting time, (b) UV-vis change with adding Ag+ concentration; (c) FTIR spectra of nanoscale GO by adding 0.5mM Ag+ after reacting 12h.Back to article page
