Mesostructured amorphous manganese oxides: facile synthesis and highly durable elimination of low-concentration NO at room temperature in air

26.03.2015 | Yanyan Du; Zile Hua; Weimin Huang; Meiying Wu; Min Wang; Jin Wang; Xiangzhi Cui; Lingxia Zhang; Hangrong Chen; Jianl ..., Chemical Communication, 2015

At a high space velocity of 120 [ ] 000 mL g−1 h−1 and a relative humidity of 50–90%, 98% removal of 10 ppm NO has been achieved for over 237 h and no sign of deactivation was observed with mesostructured amorphous manganese oxides (AMO), due to the prevention of the catalyst active sites from ...

Role of the nanocrystallinity on the chemical ordering of CoxPt100−x nanocrystals synthesized by wet chemistry

26.03.2015 | Farid Kameche; Anh-Tu Ngo; Caroline Salzemann; Marco Cordeiro; Eli Sutter; Christophe Petit, Physical Chemistry Chemical Physics, 2015

CoxPt100−x nanoalloys have been synthesized by two different chemical processes either at high or at low temperature. Their physical properties and the order/disorder phase transition induced by annealing have been investigated depending on the route of synthesis. It is demonstrated that the ...

Microwave-Assisted Hydrothermal Synthesis of Cu/Cu2O Hollow Spheres with Enhanced Photocatalytic and Gas Sensing Activities at Room Temperature

25.03.2015 | Xinwei Zou; Huiqing Fan; Yuming Tian; Mingang Zhang; Xiaoyan Yan, Dalton Transactions, 2015

Cu/Cu2O nano-heterostructure hollow spheres with a submicron diameter (200~500 nm) were prepared by a microwave-assisted hydrothermal method using Cu(OAc)2•H2O, PVP and ascorbic acid solution as the precursor. The morphology of the products could evolve as the hydrothermal time from solid spheres ...

Facile synthesis of a novel polymeric ionic liquid gel and its excellent performance for hexavalent chromium removal

24.03.2015 | Shuojue Wang; Hui-Ling Ma; Jing PENG; You-Wei Zhang; Jian Chen; Liangliang Wang; Ling Xu; Jiuqiang Li; Maolin Zhai, Dalton Transactions, 2015

A novel polymeric ionic liquid gel (PIL gel) was simply synthesized by γ-radiation-induced polymerization of ionic liquid monomer 1-allyl-3-vinylimidazolium chloride and crosslinking at ambient temperature without any additives. By changing the radiation dose, the properties of the resultant gel ...

Widening Synthesis Bottlenecks: Realization of Ultrafast and Continuous‐Flow Synthesis of High‐Silica Zeolite SSZ‐13 for NOx Removal

20.03.2015 | Zhendong Liu, Toru Wakihara, Kazunori Oshima, Daisuke Nishioka, Yuusuke Hotta, Shanmugam P. Elangovan, Yutaka Yanaba ..., Angewandte Chemie International Edition, 2015

Abstract Characteristics of zeolite formation, such as being kinetically slow and thermodynamically metastable, are the main bottlenecks that obstruct a fast zeolite synthesis. We present an ultrafast route, the first of its kind, to synthesize high‐silica zeolite SSZ‐13 in 10 min, instead of ...
