As if roaches weren’t hard enough to kill already. Scientists in Asia have devised 3D-printed scuba suits that allow ...

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), ...

氢氧化过氧化氢的光催化制备新方法。通过Mannich反应合成苯并恶嗪并经聚合、球磨制得微米级催化剂Micro-PBZ，在可见光下O2饱和水溶液中实现86.39 μmol·h?1的高产率，11次循环稳定性良好。DFT计算表明其共轭结构、 tertiary胺基团及π-π堆积促进电荷分离和O2活化，抗 ...

研究人员通过构建p型聚吡咯衍生碳(PPy-800)与n型g-C3N4纳米片(CNm)的范德华异质结，成功实现双位点O2吸附调控，显著提升2e?ORR路径的光催化H2O2产率至10415.27 μmol g?1 h?1，并展现1.31%的太阳能转化效率，为金属-free催化剂设计提供新思路。 这项突破性研究揭示了如何 ...

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 ...

H2O2通过人工光合作用将H2O和O2转化为H2O2被认为是一个环境友善的策略来取代传统的H2O2生产途径。该过程原则上涉及两个半反应: O2的双电子还原(O2+2H++2e−→H2O2，0.68 VRHE)和H2O的氧化(2H2O→H2O2+2H++2e−，1.78 VRHE)。目前，许多光催化剂已被开发耦合氧气还原和水氧化 ...

Reactive Oxygen Species (ROS) such as superoxide radicals (O2•-), hydrogen peroxide (H 2 O 2), and hydroxyl radicals (•OH) play essential roles in human physiological and pathological processes (Li et ...
