Facile coating of Co3O4 on open-cell metallic foam for N2O catalytic decomposition

Co3O4 coated on open-cell metallic foams, which can merge the catalytic activity of and advantages derived from geometry support, are promising for environmental applications such as decomposition N2O (deN2O). This study demonstrates how it is possible to easily reproducibly prepare a well-adhered layer with similar specific surface area materials prepared precipitation method (∼ 23 m2 g−1 coating) controlled thickness FeCrAlloy foams different porosity dimension by electrosynthesis Co(OH)2 followed thermal treatment (600 °C). The obtained structured catalysts show stable performance after three cycles between 250 550 °C, T50 approximately 460 comparable combustion or precipitated but provides lower pressure drop. Under operating conditions sequential test, presence NO and/or O2 in feed gas inhibits partially while H2O shows slight enhancement conversion at temperature above 450 °C.
