Synthesis and characterization of graphitic mesoporous carbon using metal–metal oxide by chemical vapor deposition method

• Instant GMC was synthesized with high yield and well graphitization using Mn/MgO.
• The Mn/MgO catalytic template assisted CVD is very cheap and easy scale up production process.
• The prepared GMC might be an ideal choice for the electronics and thermomechanical applications.

Mn/MgO was prepared by wet impregnation method and was used as a catalytic template for the growth of graphitic mesoporous carbon (GMC) using acetylene gas as carbon precursor at 900 °C by CVD method. The deposited carbon nanostructured material was separated from the catalytic template by the acid treatment, and was investigated by various physico-chemical techniques such as XRD, BET, SEM, TEM, and Raman spectroscopy. The BET surface area of GMC is ca. 200 m2 g−1. The XRD pattern and Raman spectroscopic techniques revealed the crystallinity and the degree of graphitization of mesoporous carbon. The interlayer distance of graphene sheet in GMC is around 0.34 nm. All the analytical results strongly support that the prepared mesoporous carbon to be highly ordered and well in graphitic nature. Further, the results demonstrate that the GMC synthesized by using a Mn/MgO might be a promising contender for the large-scale synthesis.
