It has been demonstrated that CH4 cannot be converted unless
under higher temperature or with a suitable catalyst. Currently,
more attention is paid to developing new catalysts to enhance
reforming reaction and reduce carbon deposition. The catalysts
based on noble metal or transition metal are widely employed,
due to their fairly good catalytic abilities [2–5]. However, the catalysts
based on noble metal face the main problem of high cost,
and the catalysts supported by transition metal are easily to be
deactivated by carbon deposition. Recently, the researchers have
performed preliminary studies on catalytic effect of different carbon
materials on CH4–CO2 reforming [6–25]. These materials are
commonly used as the catalyst or the support of a catalyst.
