Normal aerobic metabolism (via processes such as photosynthetic and respiratory electron transport chains) in plants yields varied reactive oxygen species (ROS) such as singlet oxygen (1O2), ...

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 ...

环氧丙烷(PO)是生产聚氨酯、聚酯、丙二醇等工业化学品的重要中间体。目前，生产PO的主要方法是氯醇法和共氧化法，这两种方法的加工过程都很复杂，而且容易产生多种有害副产品。以钛硅分子筛(TS-1)为催化剂，H2O2为氧化剂，甲醇(CH3OH)为溶剂的H2O2氧化生产PO ...

Introduction: Reactive oxygen species (ROS)-mediated therapies have typically been considered as noninvasive tumor treatments owing to their high selectivity and efficiency. However, the harsh tumor ...
