“…It was demonstrated that Co 3 O 4 annealed at 300 • C exhibited the weakest Co-O strength, the highest surface oxygen species activity, and thus the best toluene oxidation performance. Wang et al modulated oxygen vacancies in Co 3 O 4 by controlling the calcination temperature (200-450 • C) [30]. The catalyst prepared via a hydrothermal method followed by calcination at 200 • C gave the best propane oxidation performance due to the abundance of oxygen defects.…”

Co3O4 catalysts were prepared via carbonate precipitation and subsequent calcination under specific conditions. The different catalysts were characterized as received using several techniques and tested in the total oxidation of toluene or propane. Calcination at low temperature or under dynamic conditions resulted in Co3O4 catalysts with small crystallite sizes and large surface areas. The performances of the Co3O4 catalysts appeared to be closely related to the low-temperature reducibility. The best catalyst, Co-350D, showed a toluene oxidation rate of 44.5 nmol g−1 s−1 at 200 °C and a propane oxidation rate of 54.0 nmol g−1 s−1 at 150 °C. Meanwhile, Co-350D exhibited excellent cycling stability and decent long-term durability in both reactions.

Modulating defective oxygen of Co-based crystals by calcination temperature control for improving the catalytic removal of propane

Abstract: Oxygen defects often play an important role on catalytic performances for catalytic elimination of propane. Herein oxygen vacancies of Co3O4 crystals were modulated by controlling calcination temperature. The Co3O4 catalyst...
