Abstract: Nickel sensor action for analytical detection of hydrogen and oxygen gases is dependent on the adsorption, dissociation, and diffusion of hydrogen and oxygen. These processes and water ...
Hydrothermal experiments were conducted to evaluate the kinetics of H-2(aq) oxidation in the homogeneous H-2-O-2-H2O system at conditions reflecting subsurface/near-seafloor hydrothermal environments ...
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 ...
本研究揭示了活性氧物种(ROS)在美洲黑杨木质部发育中的关键作用。研究人员通过对比分析速生型(Wimco-109)和慢生型(Wimco-83)克隆株系发现，超氧阴离子(O2??)促进生长而H2O2导致木质化增强。研究证实NADPH氧化酶(NOX)活性差异调控ROS平衡，为造纸工业选育低木质素材料 ...

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 ...
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 ...
Chemical reactions involve the breaking and formation of chemical bonds between atoms, resulting in the formation of new substances. In order to determine the quantities of reactants and products ...
