Abstract:
The perovskite oxide BaTiO3, doped with Ge oxides oxidized methane to C2 coupled hydrocarbons. The pure barium titanate exhibited an ultraviolet absorption effect. The addition of GeO2 resulted in an increase in absorption of wavelength. Small amount of Ge decreased band gap energy. For promoted BaTiO3 catalysts with stable cation valance, electron donation ability of lattice oxygen was parallel to its ability of adsorb and active oxygen, and decreased the chance of deep oxidation of methyl radicals and C2 hydrocarbons and thus will result in an increase of C2 yield. This is an abstract of a paper presented at the 42nd Loss Prevention Symposium (New Orleans, LA 4/6-10/2008)
