Zhou, Min; Xie, Xialin; Liu, Qianyan; Zhang, Meilin; Peng, Cheng; Li, Fangqin; Liu, Qizhen; Song, Yubao; Wu, Jiang; Qiao, Zhanwei published the artcile< Spherical In2S3 anchored on g-C3N4 nanosheets for efficient elemental mercury removal in the wide temperature range>, Recommanded Product: Indium(III) chloride tetrahydrate, the main research area is spherical indium sulfide anchored carbon nitride nanosheet; efficient elemental mercury removal.

Mercury emission from coal-fired power plants has posed a great threat to the environment and human, and reducing and controlling mercury emissions has become a global environmental issue. In this work, the In2S3/g-C3N4 adsorbent was prepared by simple hydrothermal method to achieve efficient removal of Hg0 from coal-fired flue gas. When the loading value of In2S3 was 40%, the effect of removing Hg0 by as-synthesized IC-40 was the best. IC-40 showed excellent Hg0 adsorption performance in a temperature range of 80-240°. Under the condition of 120° and N2 atmosphere, the Hg0 adsorption capacity of the synthesized IC-40 reached 14.78 mg/g. The study on the impacts of flue gas components demonstrate that IC-40 has good resistance to nitric oxide, and has a slight inhibitory effect by SO2 and water vapor. According to the results of XPS and Hg-TPD, the formed main mercury compound is extremely stable HgS. In addition, DFT was conducted to calculate the adsorption energy of Hg0 on In2S3 (1 1 0) surface, which further illustrated the sulfur site served as stable adsorption site to convert Hg0 into HgS. From the above anal., IC-40 as an efficient and scientific adsorbent to remove Hg0 from coal-fired power plants is a promising tech. method.

Liu, Xiaojie; Jing, Xin; Zhao, Yong; Wang, Wei; Yu, Liangmin; Sun, Mingliang published the artcile< Small Organic Molecule Based Photoelectrodes for Efficient Photoelectrochemical Cathodic Protection>, Product Details of C8H3ClO3, the main research area is small organic mol photoelectrode efficient photoelectrochem cathodic protection.

Photoelectrochem. cathodic protection (PECCP) as a branch of photocatalysis and photoelectrochem. holds great promise for efficient anticorrosion. Organic semiconductors with tunable bandgaps and favorable optoelectronic properties were attracting more attention in the photoelectrochem. (PEC) field. However, its application for PECCP was marginally explored. Herein, the authors successfully fabricated a small organic mol. (ITIC: 3,9-bis(2-methylene-(3-(1,1- dicyanomethylene)-indanone))-5,5,11,11tetrakis(4hexylphenyl)-dithieno[2,3-d:2,3′-d’]-s-indaceno[1,2-b:5,6-b’]dithiophene) based photoelectrode for PECCP of 304 stainless steel (304SS). The PEC research proved that it could provide PECCP for 304SS with a photoinduced potential drop of 100 mV. A mol. structure design strategy was also adopted to broaden the light absorption spectrum of ITIC by halogenating the terminal group with the Cl atom. The obtained ITIC derivate (IT-2Cl)-based photoelectrode provided a higher photoinduced potential drop of 150 mV for PECCP of 304SS. More impressively, the separation of photoinduced electron-hole pairs was promoted and the electron transportation was accelerated, when introducing TiOx thin film as the electron acceptor and electron transportation channel in the photoelectrode. Consequently, the PECCP for 304SS was dramatically enhanced, with the potential drop increasing to 290 mV. The flexible mol. design strategy and improved PECCP performance proposed a guideline for the potential applications of organic semiconductor-based photoelectrodes in the PECCP field.

The benzylic C-H group of α,α-dicyanoolefins from 3-substituted 1-indanones could be significantly activated via transmission along the aromatic system, thus enabling dynamic kinetic resolution via a traditional reversible deprotonation-protonation process. Enantioenriched 9-substituted 9H-fluorene frameworks were finally constructed through an asym. vinylogous Michael addition to nitroolefins, followed by a cascade cyclization and oxidative aromatization process, under the catalysis of a chiral bifunctional thiourea-tertiary amine.

Zhu, Taotao; Ye, Xiangju; Zhang, Qiaoqiao; Hui, Zhenzhen; Wang, Xuchun; Chen, Shifu published the artcile< Efficient utilization of photogenerated electrons and holes for photocatalytic redox reactions using visible light-driven Au/ZnIn2S4 hybrid>, HPLC of Formula: 22519-64-8, the main research area is gold zinc indium sulfide photocatalyst aromatic oxidation wastewater; Aromatic alcohol; Aromatic aldehyde; Au/ZnIn(2)S(4); Hydrogen evolution; Photocatalysis.

In this study, a new photocatalytic reaction system for simultaneous selective oxidation of aromatic alcs. to corresponding aldehydes and reduction of protons to H2 has been developed. The results reveal that compared with pure ZnIn2S4, the ZnIn2S4 photocatalysts modified with noble metal gold (Au/ZnIn2S4) significantly promote the photocatalytic performance. Among them, the 0.5% Au/ZnIn2S4 nanosheets shows the highest photocatalytic activity for selective oxidation of benzyl alc. to benzaldehyde and hydrogen production, and the yields of H2 and benzaldehyde are 326.68 and 352.04 μmol under visible light irradiation for 4 h, resp. Those are about 4.4 and 3.6 times higher than those of pure ZnIn2S4 sample (74.0 μmol H2 and 98.04 μmol benzaldehyde), resp. The utilization ratio of photogenerated electrons to holes can achieve 92.8%. Addnl., the control experiments demonstrate that the photogenerated electrons and holes play significant roles during the reaction process. It is hoped that the current work can offer an avenue to utilize the photogenerated carriers more efficiently and to develop other photocatalytic reaction systems, such as nitrogen fixation and reduction of carbon dioxide.

Ahmadi-khaneghah, Aziz; Salehi, Saeed; Behniafar, Hossein published the artcile< Polystyrene networks with polyoxyethylene cross-links covalently grafted onto nano-SiO2 cores: surface-initiated ATRP and thermal investigations>, SDS of cas: 1592-20-7, the main research area is polystyrene network polyoxyethylene crosslink silica ATRP.

Crosslinked polystyrene loaded by silica nanoparticles (CPS/SNPs) with hydrophilic nature was prepared via a solvent-free surface-initiated atom transfer radical polymerization technique. Chem. immobilization of the initiator of the polyaddition reactions was performed on silica nanoparticles. Also, polyoxyethylene chains capped with styrenic end units were synthesized from the reaction of 4-chloromethyl styrene and polyethylene glycol with mole ratios of 2:1 and then used as the chain crosslinker. In addition to CPS/SNPs composite, a crosslinked material lacking silica cores (CPS) was also prepared by a similar technique. Thermal stabilities of the resulting crosslinked polystyrenes were fully investigated by thermogravimetric anal./differential thermogravimetry. The silica-containing crosslinked material clearly showed more thermal stability than the bare material. In addition, both CPS/SNPs and CPS presented thermal stabilities nearly as much as other polystyrene-silica materials reported in the literature. Thus, the polyoxyethylene crosslinks did not cause addnl. thermal sensitivity in the network obtained. Furthermore, DTA measurements demonstrated that the phase transition caused by the thermal decomposition in CPS/SNPs composite is significantly reduced due to the presence of silica cores.

Mohamed, R. M.; Mkhalid, I. A.; Shawky, Ahmed published the artcile< Facile synthesis of Pt-In2O3/BiVO4 nanospheres with improved visible-light photocatalytic activity>, COA of Formula: Cl3H8InO4, the main research area is facile synthesis platinum In2O3 BiVO4 nanospheres photocatalyst.

We present a simple synthesis of BiVO4 nanospheres co-doped with Pt and In2O3 by a hydrothermal approach. The obtained samples exhibited monoclinic phase with homogeneously dispersed Pt and In2O3 on BiVO4 dopants as indicated by XRD, TEM, and XPS, resp. The Pt-In2O3/BiVO4 photocatalyst exhibited highest surface area, lowest band gap, and much less charge recombination compared to pure, Pt or In2O3-doped BiVO4. The 1.2 gL-1 dose of Pt-In2O3/BiVO4 displayed a complete photodegradation of malachite green as an industrial model dye within 40 min with great reusability. A proposed mechanism is suggested based on the presented results.
