Abstract

Catalytic steam reforming of methane in an electric field (named "electreforming") was conducted over metal catalysts supported on CeO₂ or Ce_xZr_1-xO₂ at low temperatures such as 423 K where conventional catalytic reactions hardly proceeded. The conversion of methane was greatly increased by weak and effective application of an electric field to the catalyst bed. Use of Ce _xZr_1-xO₂ as a catalyst support promoted electreforming, the lattice oxygen of Ce_xZr_1-xO ₂ playing an important role. Energy efficiency of electreforming, reaction mechanism, and the role of lattice oxygen were investigated and are discussed in this paper.
