Abstract:
Graphitic nanofibres were synthesised using the chemical vapour decomposition method with ethylene (C2H4) as the carbon feedstock and iron (III) oxide as the catalyst. A parametric study was conducted to determine the optimum conditions for producing graphitic nanofibres by applying the Taguchi method. The result shows that the optimum conditions are at 600°C for 4 h and C2H4/H2 flowrate of 30 : 70 mL min-1. Under these conditions, the sample shows the highest yield and Brunauer-Emmett-Teller specific surface area that are 4·489 g gcat-1 h-1 and 556·65 m2 g-1 respectively. The sample is applied in H2 adsorption/desorption process at 77 K and pressure of 20 bar. The mass uptake is found to be 0·643 wt-%.Keywords: GRAPHITIC NANOFIBRE; TAGUCHI METHOD; IRON (III) OXIDE; HYDROGEN STORAGE
