Abstract
  Ti-doped MoO2 was synthesized to broaden the oxygen-to-carbon ratio operating range of MoO2 for partial oxidation of long-chain hydrocarbons by increasing the redox stability. The structure modification causes the hydrogen reduction mechanism to change from three-dimensional nuclei growth with an activation energy of 61.3 kJ mol−1 to a three-dimensional hydrogen diffusion limited model with an activation energy of 317.9 kJ mol−1. Because of the enhanced redox stability, Ti-doped MoO2 has potential as an alternative anode in direct liquid-fed solid oxide fuel cells.
