Figure 6From: Controllable preparation of Ni nanoparticles for catalysis of coiled carbon fibers growthSEM images of irregular CMC. SEM images of (a) low magnification and (b) high magnification. The irregular CMC was obtained using Ni particles on ceramic substrate under the following conditions: reaction temperature of 750°C, N2 at 100 ml/min, H2 at 60 ml/min, C2H2 at 20 ml/min, and bathing temperature of thiophene at 40°C.Back to article page
