Hydroxyl coordinated ruthenium dispersed on the surface of γ-Al₂O₃ can be applied to the selective oxidation of amines with light irradiation and an atmospheric pressure of O₂ at room temperature. Sunlight is also an effective light source for the selective aerobic oxidation of primary amines to corresponding nitriles. The high photocatalytic activity and selectivity over Ru/γ-Al₂O₃ originate from the adsorption of amines and imine intermediates on the abundant surface OH groups of the photocatalyst and further formation of Ru–amide species by ligand exchange of adsorbed amines and imine intermediates with adjacent exposed active Ru sites. Light is introduced to the system successfully via the formation of Ru–amide species, which are used as the light absorption sites of the photocatalytic selective oxidation of amines. Primary amines are directly converted to corresponding nitriles via a two-step oxidative dehydrogenation process.

Ru /γ-Al2O3上胺的光催化选择性好氧氧化为腈：载体表面的作用和强亚胺中间体的吸附

羟基协调钌分散的γ-Al系的表面上₂ ö ₃可以应用到胺与光照射和的O-大气压选择性氧化₂在室温下。阳光还是伯胺选择性好氧氧化为相应腈的有效光源。高的光催化活性和过钌选择性/γ-Al系₂ ö ₃从胺和亚胺中间体的上丰富的表面OH光催化剂和由吸附的胺和亚胺中间体的配位体交换进一步形成的Ru-酰胺种的基团的吸附起源与相邻暴露的活性Ru位点。通过以下方式成功将光引入系统形成Ru-酰胺类，用作胺的光催化选择性氧化的光吸收位点。伯胺通过两步氧化脱氢过程直接转化为相应的腈。
