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.

The research group of Professor Li Fengyan and Professor Xu Lin of Northeast Normal UniversityTwo FeTCPP-PW12 and FeTCPP-PMo12 composite catalysts were synthesized by metalloporphyrin FeTCPP and polyacid by one-step precipitation, and their photocatalytic degradation of p-phenol was studied. FeTCPP-PW12 as a catalyst under visible light irradiation, phenol conversion can reach nearly 100% within 20 minutes. In addition, the FeTCPP-PMo12 catalyst responds significantly to visible light, allowing phenol to be almost completely degraded and mineralized within 10 minutes. The two binary hybrid catalysts designed and synthesized can still maintain good activity and stability after 5 cycles.

Combining Ti4(embonate)6 cages and [Pb4(OH)4]4+ clusters for enhanced third-order nonlinear optical property

Rui-Yan Chen, Yan-Ping He*, and Jian Zhang*

By employing the Ti4L6 (L = embonate) cages to assembly with Pb2+ ions, a three-dimensional (3D) cage-cluster based framework with good third-order nonlinear optical (NLO) property is constructed.

The research group of researcher Zhang Jian of the Fujian Institute of Biological Structure, Chinese Academy of Sciences designed a tetrahedral cage consisting of Ti4L6 (L = bishydroxynaphthoate) and cubic alkane[Pb4(μ3-OH)4]PTC-290, a novel cage-cluster-based frame material composed of 4+ clusters, exhibits high stability in water, air and other common solvents. Interestingly, under the combination and synergy of cage clusters, the material exhibits an enhanced third-order nonlinear optical response.

Grain boundaries passivation of high efficiency and stable perovskite photodetector by polyoxometalate-based composite SiW11@ZIF-8

Sijie Duan, Xueying Xu, Weilin Chen*, Jingjing Zhi, and Fengrui Li

We 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.

Professor Chen Weilin’s research group of the Key Laboratory of Polyacids and Grid Materials Chemistry, Ministry of Education, Northeast Normal UniversityBy the absence of polyacid K8[α-SiW11O39]· H2O ({SiW11}) was encapsulated in an organometallic framework (ZIF-8) to prepare a polyacid-based metal-organic framework material SiW11@ZIF-8. By modifying the perovskite layer as an additive, {SiW11} not only adjusts the energy level between the perovskite layer and the electron transport layer, but also the hydrogen bond formed between the polyacid composite and the perovskite can effectively passivate the grain boundaries of the perovskite layer.

Yue 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.

Professor Wang Xiuli’s research group at Bohai UniversityBy to Anderson type polyacid[TeMo6O24]6−/[AlMo6(OH)6O18]A new “V” semi-rigid bisimidazole-bisamide ligand (4,4′-bis(1H-imidazole-4-pyridinecarboxamide)phenylmethane, L, L) was introduced into the 3− reaction system, and three sandwich-type POMOCs containing different metal ions Zn, Ni and Co were successfully synthesized under solvothermal conditions. POMOCs have excellent electrochemical sensing performance against Cr(VI), Fe(III), BrO3− and NO2−, and exhibit high catalytic oxidation activity of 99.5% and high selectivity of > 99% in heterogeneous catalytic sulfide oxidation.

Yuxin 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. And 1 was incorporated into the poly(vinyl alcohol) (PVA)/glycerol (Gly) hydrogel, forming a hydrogel composite with high proton conductivity and good flexibility.

Professor Liu Shuxia and Professor Lu Ying’s research group of Northeast Normal UniversityA novel polyacid-organic hybrid H was designed and synthesized[Zn(Hapca)3][PW12O40]7H2O (Hapca=3-aminopyrazine-2-carboxylic acid) and introduced it into polyvinyl alcohol (PVA)/glycerol (Gly) hydrogels to obtain a hydrogel composite. The composite combines the advantages of its components and achieves a proton conductivity of 1.11×10−2S at ambient humidity and 75°C·cm−1, which is the leading level among the reported polyacid matrix composites. In addition, it has good elasticity and toughness, as well as high strain sensitivity. In this work, crystalline polyacid-based organic-inorganic hybrid materials are introduced into hydrogels for the first time, which provides a new idea for converting crystalline polyacid-based inorganic-organic hybrid materials into materials with good mechanical properties.
