调节H2O2活化产生的活性氧的分布，是确保 H2O2在化学和生命科学领域高效安全使用的前提。在本文中，作者证明了通过将单原子层状 Cu5纳米团簇自组装到 FeS2表面来构建双 Cu-Fe 位点，可以高效地实现选择性 H2O2活化。与其单一的Cu或Fe对比样品不同，位于Cu5/FeS2 ...

Oncogenic transformed fibroblasts are characterized by extracellular superoxide anion generation through a membrane-associated NADPH oxidase. After cellular glutathione depletion, extracellular ...

Recently, a research team led by Prof. HUANG Weixin from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) realized the production of oxygenated ...

WE have measured the amounts of hydrogen peroxide and water produced during the hydrogen/oxygen reaction at 538° C between pressures of 300 and 400 mm in a vessel coated with boric acid, using a flow ...

The question of whether water can form hydrogen peroxide should be answered by thermodynamics (see C&EN, June 13, 2022, page 3). If a reaction is possible (spontaneous), then the change in the Gibbs ...

In bleaches and disinfectants, this strong oxidizer rips apart molecules to whiten or clean. Here it's sealed in a glass capsule that cracks open when you bend the plastic stick. Once it's unleashed, ...

The reaction of hydrogen peroxide with potassium iodide is demonstrated in a tall cylinder. Saturated potassium iodide is added to a mixture of soap, glycerin, water, and hydrogen peroxide. Oxygen and ...
