The introduction of small quantities of Pt into supported AuPd nanoparticles is found to result in enhanced catalytic efficiency in the direct synthesis of H₂O₂. This is attributed to a combination of superior H₂O₂ synthesis rates, as determined through calculation of initial rates of reaction, and an inhibition of H₂O₂ degradation pathways, achieved through the modification of Pd oxidation states. Through gas replacement experiments we demonstrate that it is possible to reach concentrations of H₂O₂ approaching those produced during initial stages of the current industrial means of H₂O₂ production.

通过将Pt掺入TiO2负载的AuPd催化剂直接合成H2O2时提高了催化剂的选择性

发现将少量Pt引入负载的AuPd纳米颗粒中会导致直接合成H ₂ O _2的催化效率提高。这归因于优越的H ₂ O ₂合成速率（通过计算初始反应速率确定）与抑制H ₂ O ₂降解途径（通过修饰Pd氧化态实现）的组合。通过气体替代实验，我们证明了有可能使H ₂ O _2的浓度接近当前H ₂ O ₂工业手段初期所产生的浓度。生产。
