The recyclable and stable ZnFe_(2)O_(4) small particle decorated one‐dimensional perylene diimide(PDI)S‐scheme heterojunction(1D PDI/ZnFe_(2)O_(4))is prepared by the hydrochloric acid‐mediated(HCl‐mediated)strategy,interestingly,the morphology of the 1D PDI/ZnFe_(2)O_(4) can also be effectively regulated by HCl‐mediated process,the existence of HCl can regulate PDI into a uniform rod structure,while the co‐existence of HCl and PDI can limit ZnFe_(2)O_(4) to become the uniform small *** importantly,based on the 1D rod structure of PDI and the small size effect of ZnFe_(2)O_(4),carriers can migrate to the surface more easily,which can improve the photocatalytic ***,due to the appropriate energy level structure,the S‐scheme heterojunction structure is formed between PDI and ZnFe_(2)O_(4),which eliminates meaningless photo‐generated charge carriers through recombination and introduces strong redox to further enhance the photodegradation effect,thereby,1D PDI/ZnFe_(2)O_(4) exhibits excellent photocatalytic ability,under the visible light irradiation,the degradation rate of tetracycline(TC)with 1D PDI/ZnFe_(2)O_(4)(66.67%)is 9.18 times that with PDI(7.26%)and 9.73 times that with ZnFe_(2)O_(4)(6.85%).This work proposes new ideas for the assembly of magnetic organic‐inorganic S‐scheme heterojunction photocatalysts.

Chemical Research in Chinese Universities 2017年第3期33卷 333-338页

作者： SONG Jiangfeng WANG Jun ZHOU Ruisha CUI Xiaobing Department of Chemistry North University of China Taiyuan 030051 P. R. China State Key Laboratory of Inorganic Synthesis and Preparative Chemistry College of Chemistry Jilin University Changehun 130012 P. R. China

A new purely inorganic 2D framework, {PMo12040Bi2（H20）2}·4H20（1）, was synthesized under solvo- thermal condition and characterized by infrared（IR） spectroscopy, thermal gravimetric analysis, UV-Vis spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction. Structural analysis reveals that compound 1 consists of Keggin unit {PMo12O40} with two bismuth atoms capping two opposite pits, leading to the bi-bismuth-capping Keggin polyoxometalate. Compound 1 not only displays excellent photodegradation activity for methyl orange（MO）, but also has a high absorption capacity for rhodamine B（RhB） and methylene blue（MB）. Moreover, compound 1 is extremely stable and easily separated from the reaction system for reuse.

C-alkylpyrogallol[4]arenes(abbreviating as PgCs,where n is the length of the associated alkyl tail),which contain four pyrogallol moieties linked together by-CHR-units to form bowl-shaped molecules,are siblings of the family of macrocycles known as calixarenes.1 In recent years,PgCs have been shown to self-assemble into a large number of PgC-based coordination complexes with different structures and properties,depending on the kind of metal ion utilized,have been *** complexes can be divided into three types according to their structural characteristics:(1)dimeric Co-,Ni-,Cu-and Zn-seamed MONCs;(2) hexameric Mg-,Co-,Ni-,Cu-,Zn-and Ga-seamed MONCs;(3) K-,Rb-and Cs-based coordination polymer(Figure 1). Solvothermal synthesis of C-propylpyrogallol[4]arene(PgC) with tetravalent titanium cations resulted in the first example of bowl-like PgC-based titanium cluster named TiPgC(Figure 2 a).To our knowledge,this TiPgC not only presents the first monomeric PgC-based coordination compound,but also the largest titanium cluster supported by the calixarene ligand up to *** studies reveal it can degrade the organic dye(methylene blue,MB) by using *** catalytic efficiency of TiPgC is about 99%in 5 hours,which is much higher than the commercial TiO(P25) with catalytic efficiency value of 18%.

第五届全国环境催化与环境材料学术会议

作者： Shouai Feng 1,2, Jianghong Zhao 1, Zhenping Zhu 1? (1. State Key Laboratory of Coal Conversion, Institute of Coal Chemistry, CAS, Taiyuan 030001, China) (2. Graduate School of the Chinese Academy of Sciences, Beijing 100039, PR China)

Through modulating experiment conditions, well fined ZnS/CNTs composites was synthesized by dropwise adding Zn（NO3）2 solution into mixture CNTs and Na2S solution and refluxing for 11h. The prepared products were characterized by transmission electron microscopy （TEM）, selected area electron diffraction （SAED）, X-ray diffraction （XRD） and Brunauer-Emmett-Teller （BET）. It is found that CNTs act as framework in the composites and ZnS NCs are anchored on the surface of CNTs or fill into the aperture of CNTs. The ZnS NCs are well crystalline cubic structure and their diameters are about 5 nm. The photocatalytic activity of ZnS nanocrystal and ZnS/CNTs composite were evaluated by methylene blue （MB） degradation through UV-vis spectroscopy measurements. The result shows that CNTs can effectively promote the photocatalytic activity of ZnS NCs.
