BLOOMFIELD HILLS, Mich., July 29, 2025--(BUSINESS WIRE)--O2 Investment Partners (www.o2investment.com) is excited to announce the promotions of Jimmy Frye to Partner, Charles Miller to Principal, and ...
为解决传统蒽醌法合成H2O2的高能耗与污染问题,研究人员通过调控π电子密度设计新型共轭聚合物催化剂A-AB,实现*OH中间体稳定化,使H2O直接氧化生成H2O2的速率达8700 μmol g-1 h-1,为双路径光催化体系提供理论依据。 当前,过氧化氢(H 2 O 2 )作为绿色氧化剂在 ...
为解决电化学发光(ECL)传感中H2O2与溶解氧(O2)的竞争反应难题,研究人员开发了氮掺杂分级多孔碳负载单原子钴位点(Co?NC SAs)作为共反应加速剂。该材料选择性激活H2O2产生活性氧,显著增强鲁米诺ECL信号,并构建三通道传感器阵列实现五种塑化剂的高灵敏度检测 ...

IT之家 10 月 3 日消息,科技媒体 newatlas 昨日(10 月 2 日)发布博文,科学家首次在分子尺度上实时观察到氢和氧原子结合形成微小的纳米水泡。 氢气(H₂)和氧气(O₂)反应生成水(H₂O)这一化学方程式,帮助我们更好地认识水的形成过程以及化学反应的 ...
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 ...
Work-life harmony occurs when we stop striving for balance and, instead, wholeheartedly give our attention to the sphere of life we are in. How do you achieve work-life balance? Companies and ...
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 ...
