| 2 | 水溶性NaYF_4:Eu^(3+)@Ag核-壳纳米晶的下转换荧光及其在葡萄糖检测中的应用(英文)显示文摘糖尿病可引起许多严重的并发症,例如失明,血压心脏病和肾衰竭等.因此,葡萄糖检测技术正在以惊人的速度发展.本文合成了水溶性的NaYF_4:Eu^(3+)@Ag核-壳纳米晶体,通过能量转移,Ag壳层可以有效吸收NaYF_4:Eu^(3+)的能量,导致Eu^(3+)离子荧光淬灭.在NaYF_4:Eu^(3+)@Ag核-壳纳米晶体的表面上固定葡萄糖氧化酶(GOx)后,通过加入一定量的葡萄糖,Ag纳米粒子可以分解成Ag^+,并伴随着Eu^(3+)的荧光恢复.结果表明,该葡萄糖检测方法具有非常低的检测限(0.12μmolL^(-1)). | 王迪 王瑞红 刘丽娟 曲阳 王国凤 李亚栋 | 2017 | Science China Materials2017，60，1： | 10 |
| 3 | In-situ structure reconstitution of NiCo2Px for enhanced electrochemical water oxidation显示文摘Gaining insight into the structure evolution of transition-metal phosphides during anodic oxidation is significant to understand their oxygen evolution reaction(OER) mechanism, and then design highefficiency transition metal-based catalysts. Herein, NiCo_2P_x nanowires(NWs) vertically grown on Ni foam were adopted as the target to explore the in-situ morphology and chemical component reconstitution during the anodic oxidation. The major factors causing the transformation from NiCo_2P_x into the hierarchical NiCo_2P_x@CoNi(OOH)_x NWs are two competing reactions: the dissolution of NiCo_2P_x NWs and the oxidative re-deposition of dissolved Co^(2+) and Ni^(2+) ions, which is based primarily on the anodic bias applied on NiCo2 Px NWs. The well balance of above competing reactions, and local pH on the surface of NiCo_2P_x NW modulated by the anodic oxidation can serve to control the anodic electrodeposition and rearrangement of metal ions on the surface of NiCo_2P_x NWs, and the immediate conversion into CoNi(OOH)_x. Consequently, the regular hexagonal CoNi(OOH)_x nanosheets grew around NiCo_2P_x NWs.Benefiting from the active catalytic sites on the surface and the sufficient conductivity, the resultant NiCo_2P_x@CoNi(OOH)_x arrays also display good OER activity, in terms of the fast kinetics process, the high energy conversion efficiency, especially the excellent durability. The strategy of in-situ structure reconstitution by electrochemical reaction described here offers a reliable and valid way to construct the highly active systems for various electrocatalytic applications. | Xue Bai Zhiyu Ren Shichao Du Huiyuan Meng Jun Wu Yuzhu Xue Xiaojun Zhao Honggang Fu | 2017 | Science Bulletin2017，62，22： | 8 |

| 5 | Co-Co304@carbon core-shells derived from metal-organic framework nanocrystals as efficient hydrogenevolution catalysts显示文摘Controllable pyrolysis of metal-organic frameworks (MOFs) in confined spacesis a promising strategy for the design and development of advanced functionalmaterials. In this study, Co-C0304@carbon composites were synthesized viapyrolysis of a Co-MOFs@glucose polymer (Co-MOFs@GP) followed by partialoxidation of Co nanoparticles (NPs). The pyrolysis of Co-MOFs@GP generated acore-shell structure composed of carbon shells and Co NPs. The controlled partialoxidation of Co NPs formed Co-Co304 heterojunctions confined in carbon shells.Compared with Co-MOFs@GP and Co@carbon-n (Co@C-n), Co-C0304@carbon-n(Co-Co304@C-n) exhibited higher catalytic activity during NaBH4 hydrolysis.Co-C0304@C-II provided a maximum specific H2 generation rate of5,360 mL.min-l.gco-1 at room temperature due to synergistic interactionsbetween Co and C0304 NPs. The Co NPs also endowed Co-C0304@C-n with theferromagnetism needed to complete the magnetic momentum transfer process. | Yanyan Liu Guosheng Han Xiaoyu Zhang Congcong Xing Chenxia Du Huaqiang Cao Baojun Li | 2017 | Nano Research2017，10，9： | 5 |
