The robust Ag-Cu₂O/Ti-foam in the gas phase oxidation of alcohols is fabricated by impregnation and calcination method. The best catalyst is Ag-3-Cu₂O-5/Ti-foam (3 wt% Ag, 5 wt% Cu), capable of oxidizing benzyl alcohol (95% benzyl alcohol conversion, 98% benzyl aldehyde selectivity) at low temperature of 260 °C. The synergistic effect between Ag and Cu₂O in the high alcohol-oxidation performance effectively works in three aspects: Ag promotes the formation of Cu₂O from Cu-species with other valences; Ag stabilizes the existence of Cu₂O; Ag is beneficial in the dehydrogenation of Cu₂O-H intermediates to drive the catalytic circle.

通过浸渍和煅烧的方法制备了醇气相氧化中的强固型Ag-Cu ₂ O / Ti泡沫。最好的催化剂是Ag-3-Cu ₂ O-5 / Ti泡沫（3 wt％Ag，5 wt％Cu），能够在低温下氧化苄醇（95％苄醇转化率，98％苄醛选择性） 260℃。Ag和Cu ₂ O在高醇氧化性能中的协同作用有效地发挥了三个方面的作用：Ag促进了具有其他价态的Cu物种中Cu ₂ O的形成；Ag稳定了Cu ₂ O的存在；Ag有利于Cu ₂ O-H中间体的脱氢以驱动催化环。
