At lower temperature, the interaction between the Ir particles and the adsorbed ethoxyl species is not strong enough to abstract H atom from the nearby CH3 group, and thus acetaldehyde acts as the key intermediate. Acetaldehyde can decompose to methane and CO and/or convert to acetone through decarbonylation.
低温时Ir粒子与吸附的乙氧基的相互作用的强度不足以从-CH3基团中提取H原子,此时乙醛是关键的反应中间物,乙醛可以裂解生成甲烷和一氧化碳或脱羰基生成丙酮。
