| 1 | 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 |
| 2 | Break Down of Vertical-Bloch-Line Chains in the First Kind of Dumbbell Domain Walls Subjected to an in-Plane Field显示文摘Experiments were statistically carried out on the behavior of the vertical-Bloch-line(VBL)chains of the first kind of dumbbell domains(IDs)in garnet bubble films subjected to an in-plane field,Hip.It was found that for IDs the critical in-plane field,(Hip)ID,above which their VBL chains disappear,is the same as that of ordinary hard bubbles(OHBs),H'ip.However,for IDS,the critical range of Hip for VBL chain softening is larger than that of OHBs.Besides,we also found some details of the softening process,e.g.,the collapse field range of the remaining IDs shrinks rapidly towards H_(0,mas),and this very narrow range can maintain until all IDs are softened. | GUO Gexin LU Wei SUN Huiyuan NIE Xiangfu MENG Guangqing HAN Baoshan | 1995 | Chinese Physics Letters1995，12，8： | 4 |

| 4 | Engineering of SnO_(2)/TiO_(2) heterojunction compact interface with efficient charge transfer pathway for photocatalytic hydrogen evolution显示文摘Fabricating an efficient charge transfer pathway at the compact interface between two kinds of semiconductors is an important strategy for designing hydrogen production heterojunction photocatalysts.In this work,we prepared a compact,stable and oxygen vacancy-rich photocatalyst(SnO_(2)/TiO_(2) heterostructure)via a simple and reasonable in-situ synthesis method.Briefly,SnCl_(2)–2H_(2)O is hydrolyzed on the TiO_(2) precursor.After the pyrolysis process,SnO_(2) nanoparticles(5 nm)were dispersed on the surface of ultrathin TiO_(2) nanosheets uniformly.Herein,the heterojunction system can offer abundant oxygen vacancies,which can act as active sites for catalytic reactions.Meanwhile,the interfacial contact of SnO_(2)/TiO_(2) grading semiconductor oxide is uniform and tight,which can promote the separation and migration of photogenerated carriers.As shown in the experimental results,the hydrogen production rate of SnO_(2)/TiO_(2) is 16.7 mmol h^(-1)g^(-1)(4.4 times higher than that of TiO_(2)),which is owing to its good dynamical properties.This work demonstrates an efficient strategy of tight combining SnO_(2)/TiO_(2) with abundant oxygen vacancies to improve catalytic efficiency. | Hongli Wang Jianan Liu Xudong Xiao Huiyuan Meng Jie Wu Chuanyu Guo Mang Zheng Xiaolei Wang Shien Guo Baojiang Jiang | 2023 | Chinese Chemical Letters2023，34，1： | 1 |
| 5 | Organic-Inorganic Interaction Recorded by Polycyclic Aromatic Steranes in Continental Epithermal Ore Deposits显示文摘Continental epithermal ore deposits are commonly associated with sedimentary organic matter,oils or solid bitumen.These organics embedded in mineral deposits can convey valuable information of the ore genesis.However,the extent to which the formation of ore minerals was recorded by organic compounds remains largely unknown,as also is how metal-rich ores interfere with the molecular proxies in the temperature regime envisaged for hydrothermal activity.The molecular compositional changes of various polycyclic aromatic steranes and polycyclic aromatic hydrocarbons and compounds derived from the Jinding Pb/Zn deposit,SW China provide new data.Aliphatic regular steranes are present as traces.The transformation from polycyclic aromatic steranes to unsubstituted polycyclic aromatic hydrocarbons is observed to show an increased trend with increasing hydrothermal alteration levels;this is consistent with the transformation from unsubstituted polycyclic aromatic hydrocarbons to heterocyclic compounds.Dehydrocyclization(aromatization)of polycyclic biological compounds and hydrodecyclization(dearomatization)of polycyclic aromatic compounds are two important reaction pathways in hydrothermal systems with moderate temperature.This detailed investigation of organicinorganic interactions of two groups of polycyclic compounds with metal-rich ores provides insights into the questions on how and to what extent the formation of Pb/Zn deposits can be recorded by organics.This work will improve our understanding of carbon reduction,oxidation or condensation in the deep Earth and the carbon exchange between the Earth's crust and mantle,and may shed light on the processes for ultra-deep hydrocarbon exploration. | XU Huiyuan LIU Quanyou JIN Zhijun ZHU Dongya MENG Qingqiang LI Pengpeng ZHU Biqing | 2023 | Acta Geologica Sinica(English Edition)2023，97，1： | 1 |
| 6 | Constructing Pd-N interactions in Pd/g-C_(3)N_(4)to improve the charge dynamics for efficient photocatalytic hydrogen evolution显示文摘The formation of chemical bonds between metal ions and their supports is an effective strategy to achieve good catalytic activity.However,both the synthesis of active metal species on a support and control of their coordination environment are still challenging.Here,we show the use of an organic compound to produce tubular carbon nitride(TCN)as a support for Pd nanoparticles(NPs),creating a composite material(NP-Pd-TCN).It was found that Pd ions preferentially bind with the electron-rich N atoms of TCN,leading to strong metal-support interactions that benefit charge transfer from g-C_(3)N_(4)to Pd.X-ray absorption spectroscopy further revealed that the metal-support interactions resulted in the formation of Pd-N bonds,which are responsible for the improvement in the charge dynamics as evidenced by the results from various techniques including photoluminescence(PL)spectroscopy,photocurrent measurements,and electrochemical impedance spectroscopy(EIS).Owing to the good dynamical properties,NP-Pd-TCN was used for photocatalytic hydrogen evolution under visible-light irradiation(λ>420 nm)and an excellent evolution rate of~381μmol·h^(-1)(0.02 g of the photocatalyst)was attained.This work aims to promote a strategy to synthesize efficient photocatalysts for hydrogen production by controllably introducing metal nanoparticles on a support and in the meantime forming chemical bonds to achieve intimate metal-support contact. | Xudong Xiao Siying Lin Liping Zhang Huiyuan Meng Jing Zhou Qi Li Jianan Liu Panzhe Qiao Baojiang Jiang Honggang Fu | 2022 | Nano Research2022，15，4： | 1 |
