Methane oxidation over PdO: Towards a better understanding of the influence of the support material

Abstract The presence of water vapor during the oxidation strong greenhouse gas methane over PdO‐based catalysts is known to result in severe inhibition and catalyst deactivation. In this context, our current study elucidates role support material for different concentrations reaction mixture. Compared a reference PdO/Al 2 O 3 catalyst, catalytic activity can be significantly enhanced when using SnO ZrO as materials remains stable 24 h operation at 823 K 12 % H O, whereas under identical conditions CH 4 conversion drops by 68 . interplay between Pd species was systematically characterized thermogravimetric analysis, temperature‐programmed reduction experiments TEM measurements. Finally, kinetic scheme derived based on experimental data.
