Electrospray ionization mass spectrometry in the negative ion mode, ESI(-)-MS, was used to investigate the iodide-catalyzed decomposition of H2O2 in aqueous medium. ESI(-)-MS monitoring revealed the ...

该研究通过稳态测量、原位红外光谱和DFT计算，揭示了不同尺寸（1.8 nm和11.8 nm）PdχAu催化剂表面Pd原子的分布与反应性能的关系。结果表明，小尺寸催化剂因Pd原子暴露度更高、表面重构更显著，表现出更强的H2O2选择性及反应速率，且Pd-Au合金的电子结构和几何 ...

为解决传统蒽醌法合成H2O2的高能耗与污染问题，研究人员通过调控π电子密度设计新型共轭聚合物催化剂A-AB，实现*OH中间体稳定化，使H2O直接氧化生成H2O2的速率达8700 μmol g-1 h-1，为双路径光催化体系提供理论依据。 当前，过氧化氢（H 2 O 2 ）作为绿色氧化剂在 ...

When I first spoke with owner Brittany Van Domelen about O2, the big news was that her slick Pilates and yoga studio, which has been a mainstay of the Aspen boutique fitness scene for nearly two ...

自1818年首次发现过氧化氢（H2O2）以来，它因其高活性氧含量、广泛的pH适应性和无毒副产物（仅为水和氧气）而备受世人瞩目，被视为最有价值的化学品之一，因此广泛应用于如漂白、消毒、污染物降解及化学有机合成等多个工业领域。然而，H2O2的大规模工业 ...

光合成过氧化氢（H2O2）是太阳能的收集和转化的一种有效策略，但光合成H2O2的高效过程是由光生成的电子-空穴对重组导致的H2O2产率降低所驱动的，特别是在没有牺牲剂的情况下。基于此，厦门大学黄小青教授和韩佳甲助理教授、广东工业大学徐勇教授等人报道 ...

Abstract: While III-V photovoltaics are among the most efficient, they suffer from a high manufacturing cost. One of the methods of reducing this cost is through GaAs substrate reuse, with a promising ...
