The Interaction of H2O2 with TiAlPO-5 Molecular Sieves. Probing the Catalytic Potential of Framework Substituted Ti Ions.
08-05-2013 | Mario Chiesa; Gloria Berlier; Sara Maurelli; Chiara Novara; Almudena Alfayate, Physical Chemistry Chemical Physics, 2013
A combination of EPR, ENDOR and HYSCORE experiments has been used to investigate the reactivity of hydrogen peroxide with TiAlPO-5 materials under both hydrated and anhydrous conditions. Superoxide radical anions, generated upon reaction, are used as paramagnetic probes to investigate the ...
A study into Stille cross‐coupling reaction mediated by palladium catalysts deposited over siliceous supports bearing N‐donor groups at the surface
29-04-2013 | Miloslav Semler, Jiří Čejka, Petr Štěpnička, Applied Organometallic Chemistry, 2013
Mesoporous molecular sieve SBA‐15 and conventional silica gel were grafted with 3‐[2‐(diethylamino)ethylamino]propyl groups and used as supports for the preparation of deposited palladium catalysts, which were subsequently evaluated in Stille cross‐coupling reaction of aryl bromides. The ...
Material Advancements in Fabrication of Mixed‐Matrix Membranes
24-04-2013 | R. Nasir, H. Mukhtar, Z. Man, D. F. Mohshim, Chemical Engineering & Technology, 2013
Abstract The mixed‐matrix membrane (MMM) is a new membrane material for gas separation and plays a vital role for the advancement of current membrane‐based separation technology. Blending between inorganic fillers like carbon molecular sieves, zeolite, metal oxides, silica and silica ...
Aldehyde Self-Condensation Catalysis by Aluminum Aminoterephthalate Metal–Organic Frameworks Modified with Aluminum Isopropoxide
22-04-2013 | Lev Bromberg; Xiao Su; T. Alan Hatton, Chemistry of Materials, 2013
Porous materials based on aluminum(III) 2-aminoterephthalate metal organic frameworks (MOFs NH2MIL101(Al) and NH2MIL53(Al)) and their composites with aluminum isopropoxide (Al-i-Pro) are studied as sorbents of vapors of volatile aldehydes and catalysts of acetaldehyde dimerization to ethyl ...
Synthesis of DNL‐6 with a High Concentration of Si (4 Al) Environments and its Application in CO2 Separation
18-04-2013 | Xiong Su, Peng Tian, Dong Fan, Qinghua Xia, Yue Yang, Shutao Xu, Lin Zhang, Ying Zhang, Dehua Wang, Zhongmin Liu, ChemSusChem, 2013
Abstract The synthesis of DNL‐6 with a high concentration of Si (4 Al) environments [Si/(Si+Al+P)=0.182 mol, denoted as M‐DNL‐6] is demonstrated. This represents the highest reported concentration of such environments in silicoaluminophosphate (SAPO) molecular sieves. Adsorption studies ...
Efficient Access to Trifluoromethyl Diarylpyrrolines and their N‐Oxides through Enantioselective Conjugate Addition of Nitromethane to β,β‐Disubstituted Enones
18-04-2013 | Hiroyuki Kawai, Zhe Yuan, Takashi Kitayama, Etsuko Tokunaga, Norio Shibata, Angewandte Chemie International Edition, 2013
The cupreidinium salt 1 catalyzes the highly enantioselective conjugate addition of nitromethane to β‐aryl‐β‐trifluoromethyl aryl enones (2). The biologically important chiral pyrrolines 4 and N‐oxide 5, having a trifluoromethylated all‐carbon quaternary chiral center, were easily ...

Solution–processable exfoliated zeolite nanosheets purified by density gradient centrifugation
26-03-2013 | Kumar Varoon Agrawal, Berna Topuz, Marta Navarro, Zheyu Jiang, Kevin Nguenkam, Bahman Elyassi, Lorraine F. Francis, ..., AIChE Journal, 2013
Abstract Highly crystalline exfoliated MFI‐nanosheets can pave the way for large scale deployment of sub‐500‐nm zeolite membranes due to their processing and packing advantages. Exfoliated MFI‐nanosheets prepared by melt compounding contain a large amount of polymer and unexfoliated ...
Modeling and optimization of gas transport characteristics of carbon molecular sieve membranes through statistical analysis
25-03-2013 | Vahid Pirouzfar, Seyed Saeid Hosseini, Mohammad Reza Omidkhah, Abdolsamad Zarringhalam Moghaddam, Polymer Engineering and Science, 2013
Abstract This study aims to propose the importance of employing statistical analysis and modeling for investigation on the design and optimization of CMS membranes for gas separation. The factorial methodology is used to optimize permeability and selectivity through implementing the ...
