The catalysts used in methane oxidation and reformed gas reactions are mainly supported metal catalysts, and their metal active components are divided into two categories: noble metals such as Pd, Ru, Rh, Pt, Ir, etc. and non-precious metals such as Ni, Co, Fe, etc. Ⅷ Group transition metals.
Classification | Electrical Conductivity | Examples of Catalytic Reactions | Active Components |
Metal | Electrical Conductivity (Oxidation and Reduction) | Selective Hydrogenolysis Selective Oxidation | Fe,Ni,Pt Pd,Cu,Ni,Pt Ag,Pd,Cu |
Transition Metal Oxide Sulfide | Semiconductor (Oxidation and Reduction) | Selective Hydrogenation,Hydrogenolysis Hydrogenolysis Oxidation | ZnOCuONiO Cr₂O3 MoS₂,Cr₂O3 Fe₂O3-MoO3 |
