Fast degradation of phenol over porphyrin-polyoxometalate composite photocatalysts under visible light
Zhinan Xia, Libo Wang, Qiu Zhang, Fengyan Li*, and Lin Xu*Two new composite catalysts were designed with [5,10,15,20-tetra-(4-carboxylphenyl)-porphyrinato]-ferric chloride (FeTCPP) and H3PW12O40 (PW12)/H3PMo12O40 (PMo12). As final result, phenol was almost completely photodegraded in 10 min with FeTCPP-PMo12 photocatalyst.东北师范大学历凤燕教授和许林教授课题组将金属卟啉FeTCPP和多酸通过一步沉淀法合成了两种FeTCPP-PW12和FeTCPP-PMo12复合催化剂,并研究了其对苯酚的光催化降解。FeTCPP-PW12作为催化剂在可见光照射下,20分钟内苯酚转化率可以达到近乎100%。此外,FeTCPP - PMo12催化剂对可见光的响应显著,在10分钟内可使苯酚几乎完全降解和矿化。设计合成的两种二元杂化催化剂在经过5次循环后仍能保持良好的活性和稳定性。Polyoxometalates, 2022, 1, 9140001https://doi.org/10.26599/POM.2022.9140001

Grain boundaries passivation of high efficiency and stable perovskite photodetector by polyoxometalate-based composite SiW11@ZIF-8Sijie Duan, Xueying Xu, Weilin Chen*, Jingjing Zhi, and Fengrui LiWe modified the perovskite layer by dispersing the vacancy polyoxometalates K8[α-SiW11O39]·H2O ({SiW11}) in ZIF-8. SiW11@ZIF-8 can tune the energy levels between the perovskite layer and the electron transport layer and effectively passivate the grain boundaries. The photocurrent of the device reaches 41.95 μA, which is three times higher than the blank one, and it can still maintain more than 90% stability for nearly 700 hours in the unpackaged condition.东北师范大学多酸与网格材料化学教育部重点实验室陈维林教授课题组通过将缺位型多酸K8[α-SiW11O39]·H2O ({SiW11})封装在有机金属框架(ZIF-8)中制备了多酸基金属有机框架材料SiW11@ZIF-8。将其作为添加剂对钙钛矿层进行修饰,{SiW11}不仅可调节钙钛矿层和电子传输层之间能级,而且由其形成的多酸复合材料与钙钛矿之间形成的氢键可有效钝化钙钛矿层的晶界。Polyoxometalates, 2022, 1, 9140003https://doi.org/10.26599/POM.2022.9140003 Anderson-type polyoxometalate-based sandwich complexes bearing a new “V”-like bis-imidazole-bis-amide ligand as electrochemical sensors and catalysts for sulfide oxidationYue Zhang, Xiang Wang, Yue Wang, Na Xu, and Xiu-Li Wang*Three Anderson-type polyoxometalate-based sandwich-like complexes were constructed from Zn2+/Ni2+/Co2+ ions and a new “V”-like bis-imidazole-bis-amide ligand, which not only exhibit excellent electrochemical sensing performance for Cr(VI), Fe(III), BrO3− and NO2− ions, but also can serve as catalysts for oxidation of sulfide.渤海大学王秀丽教授课题组通过向Anderson型多酸[TeMo6O24]6−/ [AlMo6(OH)6O18]3−的反应体系中引入一种新的“V”状半刚性双咪唑-双酰胺配体(4,4'-双(1H-咪唑-4-吡啶甲酰胺)苯基甲烷,L),在溶剂热条件下成功合成了三种含有不同金属离子Zn、Ni、Co的夹心型POMOCs。POMOCs对Cr(VI)、Fe(III)、BrO3−和NO2−具有优异的电化学传感性能,并在多相催化硫化物氧化中表现出99.5%的高催化氧化活性和>99%的高选择性。Polyoxometalates, 2022, 1, 9140004https://doi.org/10.26599/POM.2022.9140004 Construction of hydrogel composites with superior proton conduction and flexibility using a new POM-based inorganic–organic hybridYuxin Wang, Ying Lu*, Wensha Zhang, Tianyi Dang, Yanli Yang, Xue Bai, and Shuxia Liu*In this study, a new conductive polyoxometalate (POM)-based inorganic–organic hybrid H[Zn(Hapca)3][PW12O40]·7H2O 1 (Hapca = 3-aminopyrazine-2-carboxylic acid), was synthesized.
