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 ...

针对病原体感染威胁全球公共卫生的难题，研究人员开发了FeMoS4/MXene生物异质结酶(FM BioHJzyme)。该材料在近红外光(NIR)激发下 ...

Serving as a spinoff to the original H2O: Just Add Water series, the Australian kids show Mako Mermaids: An H2O Adventure (also known as Mako: Island of Secrets, Mako Mermaids, or Secret of Mako ...

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 ...

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 ...

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 ...
