| 1 | Controllable preparation of ZnO porous flower through a membrane dispersion reactor and their photocatalytic properties显示文摘Three dimensional (3D) flower-like basic zinc carbonate constructed by multilayered nanoplates were rapidly prepared at room temperature through the direct precipitation method coupled with membrane dispersion technology, and porous ZnO with similar structures could be obtained after calcining the precursor. The structural properties of the products before and after the calcining process were characterized by SEM, TEM and XRD.The supersaturation of the reaction system due to the membrane dispersion played an important role in the formation of uniform Zn_5(CO_3)_2(OH)_6 precursors. A plausible mechanism was proposed for the formation of the flower-like ZnO assembled by nanoplates composed of nanoparticles. The obtained ZnO microspheres showed excellent photocatalytic properties, which could be attributed to the open structure and remarkable amount of porous nanoplates. | Feng Zhang Zhilong Xu Kun Wang Rizhi Chen Zhaoxiang Zhong Weihong Xing | 2018 | Chinese Journal of Chemical Engineering2018，26，10： | 5 |
| 2 | Facile synthesis of hierarchically porous carbons by controlling the initial oxygen concentration in-situ carbonization of ZIF-8 for efficient water treatment显示文摘The state-of-the-art approaches for adjusting the structural characteristics of porous carbons are the aftertreatments, which are complicated and time consuming. In this work, a facile approach was developed, i.e., controlling the initial oxygen concentration in-situ during the direct carbonization of zeolitic imidazole framework-8(ZIF-8), to adjust the pore structure and prepare hierarchically porous carbons. The introduction of oxygen can significantly affect the crystalline and pore structures of porous carbons, and promote the pore widening and the formation of mesopores. An appropriate initial oxygen concentration can notably enhance the surface area and mesopore volume of porous carbon, and then improve the adsorption capacity toward methylene blue(MB) dye from water by 3.4 times. The developed approach is more efficient at lower carbonization temperature.Moreover, the introduction of oxygen can increase the ratio of HO\\C_O groups on the carbon surface, leading to enhanced interaction with MB molecules and higher adsorption capacity toward MB. The as-prepared porous carbons exhibit superior adsorption capacities toward MB dye as compared to the reported ZIF-8 derived carbons. These findings would aid the development of porous carbon materials with high performance. | Na Zhou Yan Du Chunyu Wang Rizhi Chen | 2018 | Chinese Journal of Chemical Engineering2018，26，12： | 1 |
| 3 | Selective Reduction of Nitroarenes with Molybdenum Disulfide显示文摘商业 MoS2 被发现是为到有在温和条件下面的肼的相应苯胺的硝基苯的减小的高度选择的催化剂。MoS2 比为到相应苯胺的功能的硝基苯的减小的高贵金属催化剂便宜得多不仅,而且更选择。有卤化物的硝基苯(F, Cl, Br 并且我) 有选择地被减少,并且相应苯胺在优秀收益被获得,并且没有 dehalogenation 被检测。功能的组象 NH2 那样,哦,链烯组在 nitro 混合物的减小期间被容忍。p-chloronitrobenzene 的减小与肼分别地在 MoS2 和 Pd/C 上被学习。p-chloroaniline 的收益与在完整的变换的 Pd/C 比那与 MoS2 是高得多的。 | Lei Huang Pingfei Luo Man Xiong Rizhi Chen Yong Wang Weihong Xing Jun Huang | 2013 | Chinese Journal of Chemistry2013，31，8： | 1 |
