Scalable fabrication and active site identification of MOF shell-derived nitrogen-doped carbon hollow frameworks for oxygen reductionJiashen Meng1,Ziang Liu1,Xiong Liu1,Wei Yang1,Lianzhou Wang2,Yan... active sites is highly desired. Besides, due to the complexity of nitrogen species, the identification of active nitrogen sites for ORR remains challenging. Herein, we develop a facile and scalable......
First principles study of Fenton reaction catalyzed by FeOCl:reaction mechanism and location of active siteXuan-Xuan Ji,Hai-Feng Wang,Pei-Jun HuKey Laboratory for Advanced Materials,Research...,results in the formation of active unit [Fe2+-Fe3+].On[Fe2+-Fe3+]unit,H2 O2 can easily break its O-O bond and OH at Fe3+ can desorb as OH radical,while the other OH at Fe2+ couples with the surface H......
active service protocol for migrating workflows WANG Rui(王睿)1, 2, ZENG Guang-zhou(曾广周)1 1. School of Computer Science and Technology, Shandong University, Jinan 250061, China; 2. School of Computer... intelligent forwarding of service recommendations, a novel group-based active service (GAS) protocol for migrating workflows was proposed. This protocol did not require service requesters to discover......

recognized because of its excellent optical properties,low cost, and environment friendliness. In the g-C3N4 intrinsic frameworks, carbon atom tends to be the reducing active site, while nitrogen atom tends to be the oxidizing active site and reducing active site according to the difference of electronegativity. However, the quantity and quality of these active sites are affected by many factors......
and NO on surface active sites[59] 综上所述,利用活性位增加法增强材料的抗硫脱汞性能主要有2种途径:一种是借助Ce,Nb,Cr和Co等金属元素的掺杂,对脱汞体系表面电荷进行重组,制造氧缺陷,并借助O2来补充表面活性氧；另一种则是通过反应气氛调控,增加活性烟气组分(如O2,NO,HCl)的体积分数,以期在脱汞体系表面创造更多的活性位点,抑制SO2对脱汞的不利影响. 3 ...-modified active coke for mercury removal from municipal solid waste incineration flue gas[J].
