The effect of reduction temperature on Co-Mo/Al2O3catalysts for carbon nanotubes formation (2007)
Journal Article
Chai, S. P., Zein, S. H. S., & Mohamed, A. R. (2007). The effect of reduction temperature on Co-Mo/Al2O3catalysts for carbon nanotubes formation. Applied catalysis. A, General, 326(2), 173-179. https://doi.org/10.1016/j.apcata.2007.04.020

Catalyst reduction temperature was observed to affect the yield and diameter uniformity of carbon nanotubes (CNTs) produced on Co-Mo/Al 2 O 3 catalysts. The results show that on the whole, the reduced catalysts gave higher carbon yield. The CNTs obta...

Synthesis of manganese oxide/carbon nanotube nanocomposites using wet chemical method (2007)
Journal Article
Zein, S. H. S., Yeoh, L. C., Chai, S. P., Mohamed, A. R., & Mahayuddin, M. E. M. (2007). Synthesis of manganese oxide/carbon nanotube nanocomposites using wet chemical method. Journal of Materials Processing Technology, 190(1-3), 402-405. https://doi.org/10.1016/j.jmatprotec.2007.03.104

Novel material with peculiar properties can be obtained by introducing foreign materials into the inner cavity of carbon nanotubes. It has been suggested that the materials encapsulated into the hollow regions of carbon nanotubes could result in a si...

Synthesizing carbon nanotubes and carbon nanofibers over supported-nickel oxide catalysts via catalytic decomposition of methane (2007)
Journal Article
Chai, S. P., Zein, S. H. S., & Mohamed, A. R. (2007). Synthesizing carbon nanotubes and carbon nanofibers over supported-nickel oxide catalysts via catalytic decomposition of methane. Diamond and related materials, 16(8), 1656-1664. https://doi.org/10.1016/j.diamond.2007.02.011

Supported-NiO catalysts were tested in the synthesis of carbon nanotubes and carbon nanofibers by catalytic decomposition of methane at 550 °C and 700 °C. Catalytic activity was characterized by the conversion levels of methane and the amount of carb...

Study of hydrogen storage by carbonaceous material at room temperature (2007)
Journal Article
Hassan, N. H. A., Mohamed, A. R., & Zein, S. H. S. (2007). Study of hydrogen storage by carbonaceous material at room temperature. Diamond and related materials, 16(8), 1517-1523. https://doi.org/10.1016/j.diamond.2006.12.042

Recently, many studies have been reported about a variety of carbon materials in adsorbing hydrogen. Regarding that, hydrogen adsorption in different carbonaceous materials was investigated at room temperature, 298 K and three different pressures whi...
