Hydrogen peroxide is a highly reactive and relatively unstable molecule, therefore pure (H₂O₂)_N clusters are difficult to generate. In order to investigate the solvent effects on the H₂O₂ reactivity, experiments with H₂O₂ clusters are desirable. We have generated (H₂O₂)_N clusters on free nanoparticles in molecular beams using a pickup technique. The individual H₂O₂ molecules were evaporated from the stable complex of urea with hydrogen peroxide (UHP) and they were picked up by Ar_M and (H₂O)_M nanoparticles in a molecular beam prepared by supersonic expansion. The clusters were probed by the time-of-flight mass spectrometry after electron ionization. The mass spectra showed that several H₂O₂ molecules could be deposited on both Ar_M and (H₂O)_M nanoparticles. On Ar_M, they coagulate and generate (H₂O₂)_N clusters with N ≥ 20, while on ice nanoparticles the coagulation is inhibited on the timescale of our experiment (∼ 0.7 ms). The mass spectra suggest that there is no significant contamination of the (H₂O₂)_N clusters with oxygen and water, which would be the products of H₂O₂ thermal decomposition. The proposed method represents a way of producing (H₂O₂)_N clusters for future experiments.

过氧化氢是高反应性且相对不稳定的分子，因此难以生成纯的（H ₂ O ₂）_N团簇。为了研究溶剂对H ₂ O ₂反应性的影响，需要对H ₂ O ₂团簇进行实验。我们已经使用拾取技术在分子束中的自由纳米粒子上生成了（H ₂ O ₂）_N簇。从尿素与过氧化氢（UHP）的稳定络合物中蒸发出单个H ₂ O ₂分子，并用Ar _M和（H ₂O）通过超音速膨胀制备的分子束中的_M纳米粒子。在电子电离后，通过飞行时间质谱对簇进行探测。质谱表明，几个H ₂ O ₂分子可以沉积在Ar _M和（H ₂ O）_M纳米颗粒上。Ar上_中号就会凝结，并且生成（H ₂ ö ₂）_Ñ与群集Ñ  ≥20，同时在冰上纳米颗粒凝固是在我们的实验中（〜0.7毫秒）的时间刻度抑制。质谱表明（H ₂ O ₂）_N与氧气和水团聚，这将是H ₂ O ₂热分解的产物。所提出的方法代表了一种产生（H ₂ O ₂）_N团簇的方法，以用于将来的实验。
