“…However, there is some disagreement in the literature over the surface form which is most active. Oh and co-workers [19,20]and Hicks et al [15,16] argue that the metal surface is more active than the oxide surface, whereas Burch and co-workers [21][22][23], Farrauto et al [24,25]and Primet and co-workers [26][27][28] consider the oxide surface as the most active phase.…”

“…Esta mesma situação, usar uma propriedade obtida com o catalisador reduzido, sabendo-se que em condições reacionais o Pd se encontra na forma oxidada, foi considerada por Urbano e colaboradores 31 [8][9][10][11][12][13] .…”

“…Diferentes formas ativas de paládio têm sido propostas para a combustão de CH 4 , tais como partículas de óxido de paládio altamente dispersas, cristais de Pd encobertos por uma camada de óxi-do, oxigênio quimissorvido em Pd e reconstrução do óxido de Pd em condições de reação [8][9][10][11][12][13] , considerando sempre a transformação reversível PdO↔Pd o como a etapa fundamental na performance do paládio na combustão catalítica de metano.…”

“…Unfortunately Pd-PdO catalyst morphology and its reactions with methane are complex, and lead to complex behaviors such as deactivation at high temperature (above about 750 C / 1380 F), hysteresis in reaction rate over heating and cooling cycles [4][5][6][7], and oscillations in activity and temperature [8][9][10][11]. Lightoff and extinction temperatures are well above 300 C (570 F) for fuel-lean methane reaction on Pd-based catalysts, thus requiring the use of a preburner in many engine applications [12][13].…”
