Fig. 1From: Reduced Graphene Oxide/Carbon Nanotube Composites as Electrochemical Energy Storage Electrode ApplicationsSEM images of ERGO (a) and ERGO/CNTs obtained from GO/CNTs with different mass ratios: b GO/CNTs = 100:1, c GO/CNTs = 50:1, and d GO/CNTs = 10:1; the inset images in (b) are photo pictures of GO/CNTs before and after electrochemical reductionBack to article page
