Carbon nanotube-based Pt/Pd and Ru catalysts, independently synthesized by a microwave reaction technique, show good catalytic activity for CO2 reduction in the contexts of dry reforming (DR) of methane (CH4 + CO2 -> 2CO + 2H2) and reverse water gas shift (RWGS) (H2 + CO2 -> CO + H2O). Reaction temperatures range from 773 to 973 K, with system pressure at 30 psig. The feed molar ratios CH4/CO2 and CO2/H2 are varied from 0.5 to 2.0. Reactant conversions in DR and RWGS are strongly influenced by temperature and feed molar ratio, but insignificantly affected by flow rate.
