Evidence of NC-templated crystallisation of Ag nanobelt structures. (a,b) N1s XPS plots of UPy-MWCNTs (before and after sonication) and UPy-GO films after thermal treatment at low (120 °C) and high (350 °C) temperatures. (c) Typical FESEM image of Ag nanoparticles with sonicated UPy-MWCNTs synthesized by solution reduction of Ag+ ions. (d) FESEM image of Ag nanobelt structures on UPy-GO sheet. (e) FESEM images of Ag nanostructures on thermally-treated UPy-GO sheet. Inset images in (d) and (e) show water droplet images and water contact angles on corresponding GO surfaces.
