本文报道了一种边缘定位不对称CoN2O2单原子催化剂，通过跨尺度电极设计将气扩散电极（GDE）活性区域扩展至浸润区，解决了空气自呼吸阴极O2传质受限和易浸润的难题。该策略实现了738.5 mg L-1的H2O2产率（25 mA cm-2，6小时），为无曝气H2O2电合成提供了新范式。

研究人员开发了聚多巴胺修饰卤氧化铋(BiOX)催化剂，通过界面p轨道耦合增强O2吸附并降低·O2?转化能垒，实现3083 μmol g?1 h?1的高效压电催化H2O2生产，为机械能转化提供新策略。

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 ...

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 ...
