When an aqueous Au(III) solution containing 1-butanol was sonicated under Ar, Au(III) was reduced to Au(0) to form Au particles. This is because various reducing species are formed during sonication, but the reactivity of these species has not yet been evaluated in detail. Therefore, in this study, we analyzed the effects of Au(III) on the rates of the formation of gaseous and water-soluble compounds (CH₄, C₂H₆, C₂H₄, C₂H₂, CO, CO₂, H₂, H₂O₂, and aldehydes), and the rate of Au(III) reduction as a function of 1-butanol concentration. The following facts were recognized: 1) for Au(III) reduction, the contribution of the radicals formed by the pyrolysis of 1-butanol was higher than that of the secondary radicals formed by the abstraction reactions of 1-butanol with ·OH, 2) ·CH₃ and CO acted as reductants, 3) the contribution of ·H to Au(III) reduction was small in the presence of 1-butanol, 4) aldehydes and H₂ did not act as reductants, and 5) the types of species that reduced Au(III) changed with 1-butanol concentration.

当在Ar下超声处理包含1-丁醇的Au（III）水溶液时，Au（III）还原为Au（0）以形成Au颗粒。这是因为在超声处理过程中形成了各种还原性物质，但是尚未详细评估这些物质的反应性。因此，在本研究中，我们分析了Au（III）对气态和水溶性化合物（CH ₄，C ₂ H ₆，C ₂ H ₄，C ₂ H ₂，CO，CO ₂，H ₂，H ₂ O ₂和醛），以及Au（III）还原速率与1-丁醇浓度的关系。认识到以下事实：1）对于Au（III）还原，由1-丁醇热解形成的自由基的贡献高于由1-丁醇与·OH，2的抽象反应形成的仲自由基的贡献。 ）·CH ₃和CO充当还原剂； 3）在1-丁醇存在下·H对Au（III）还原的贡献很小； 4）醛和H ₂不充当还原剂； 5）类型还原Au（III）的物种的数量随1-丁醇浓度的变化而变化。
