New heterogeneous catalytic systems based on highly porous ceramic materials modified with immobilized d-metal cage complexes for H2 production from CH4

The Fe, Co and Ru clathrochelates bearing terminal polar groups were immobilized as the precursors of single atom catalysts on a surface of highly porous ceramic material used as the support. The obtained materials, which were evaluated for a syngas production from CH₄ based on its partial oxidation and dry reforming reactions, did not catalyze the partial oxidation of CH₄, while that based on immobilized Ru^II clathrochelate served as the active and selective catalyst of dry reforming conversion of CH₄+CO₂ mixture into a syngas containing the equimolar amounts of H₂ and CO.
