Growth of ZIF-8 membrane on the inner-surface of ceramic hollow fiber via cycling precursors

17-09-2013 | Kang Huang; Ziye Dong; Qianqian Li; Wanqin Jin, Chemical Communication, 2013

For the first time, a ZIF-8 membrane was grown on the inner surface of the ceramic hollow fiber via cycling precursors. The inner-side hollow fiber ZIF-8 membrane exhibits good performance for recovering hydrogen.


Efficient PdNi and PdNi@Pd-Catalyzed Hydrogen Generation via Formic Acid Decomposition at Room Temperature

12-09-2013 | Xinbo ZHANG; Limin Wang; Yulin Qin; Jun Wang, Chemical Communication, 2013

Formic acid (FA) holds great potential as a convenient source of hydrogen for sustainable chemical synthesis and renewable energy storage. Herein, non-noble metal nickel (Ni) exhibits superior promoting effect in improving the catalytic activity of Pd toward high activity and selectivity FA ...


Electrocatalytic hydrogen evolution from neutral water by molecular cobalt tripyridine–diamine complexes

11-09-2013 | Peili Zhang; Mei Wang; Frederic Gloaguen; Lin Chen; François Quentel; Licheng Sun, Chemical Communication, 2013

A cobalt complex with a tripyridine–diamine pentadentate ligand was found to be a highly active catalyst for electrochemical H2 production from neutral water, with an activity of 860 mol H2 (mol cat)−1 h−1 (cm2 Hg)−1 over 60 h CPE experiment at −1.25 V in a pH 7 phosphate buffer solution, without ...


Buckyball-, carbon nanotube-, graphite-, and graphene-enhanced dehydrogenation of lithium aluminum hydride

11-09-2013 | Chih-Ping Hsu; De-hao Jiang; Sheng-Long Lee; Jain-Long Horng; Ming-Der Ger; Jeng-Kuei Chang, Chemical Communication, 2013

Compared to C60, carbon nanotubes, and graphite, graphene more effectively lowers the dehydrogenation temperature and improves the dehydrogenation kinetics of LiAlH4. With 15 wt% graphene incorporation, the initial hydrogen release temperature is [[similar]] 80 °C (60 °C lower than that of ...


Direct splitting of pure water into hydrogen and oxygen using rutile titania powder as a photocatalyst

28-08-2013 | Kazuhiko Maeda, Chemical Communication, 2013

Direct splitting of pure water into hydrogen and oxygen was demonstrated using the rutile TiO2 powder under band gap irradiation. The successful water splitting results at least in part from the intrinsic properties of the rutile surface that is less sensitive to photoreduction of O2, a reverse ...


Revealing and accelerating slow electron transport in amorphous molybdenum sulphide particles for hydrogen evolution reaction

28-08-2013 | Heron Vrubel; Thomas Moehl; Michael Grätzel; Xile Hu, Chemical Communication, 2013

Electrochemical impedance spectroscopy is used to identify a slow electron transport process in hydrogen evolution catalysed by amorphous molybdenum sulphides on glassy carbon. A new chemical synthesis leads to an amorphous molybdenum sulfide catalyst with a higher electronic conductivity. ...


Synthesis of Ultrathin CdS Nanosheets as Efficient Visible-light-driven Water Splitting Photocatalysts for Hydrogen Evolution

28-08-2013 | You Xu; Weiwei Zhao; Rui Xu; Yanmei Shi; Bin Zhang, Chemical Communication, 2013

Ultrathin CdS nanosheets with a thickness of ~ 4 nm have been synthesized through an ultrasonic-induced aqueous exfoliation method involving lamellar CdS-DETA hybrid nanosheets as starting materials and L-cysteine as a stabilizing agent. The as-obtained CdS ultrathin nanosheets exhibite efficient ...


Hydrogen bonded polymeric multilayer films assembled below and above the cloud point temperature

28-08-2013 | Andre Antunes; Marijke Dierendonck; Gertjan Vancoillie; Jean Paul Remon; Richard Hoogenboom; Bruno De Geest, Chemical Communication, 2013

Polymeric multilayer films assembled via hydrogen-bonding are witnessing increased interest by the scientific community. Here we report on hydrogen bonded multilayers from tannic acid and neutral poly(2-oxazoline)s. Importantly we demonstrate, to the best of our knowledge, for the first time that ...


Hydrogen-bond mediated regio- and enantioselectivity in a C–H amination reaction catalysed by a supramolecular Rh(II) complex

22-08-2013 | Thorsten Höke; Eberhardt Herdtweck; Thorsten Bach, Chemical Communication, 2013

Enantioselective (up to 74% ee) and regioselective C–H amination reactions of 3-benzylquinolones were achieved with a chiral C2-symmetric Rh(ii) complex exhibiting two lactam binding sites for substrate coordination via hydrogen bonds.


Zeolite-imidazolate framework (ZIF-8) membrane synthesis on mixed-matrix substrate

14-08-2013 | Eva Barankova; Neelakanda Pradeep; Klaus-Viktor Peinemann, Chemical Communication, 2013

A thin, dense, compact and hydrogen selective ZIF-8 membrane was synthesized on a polymer/metal oxide mixed-matrix support by secondary seeding method. The new concept of incorporating ZnO particles to the support and applying a PDMS coating on the ZIF-8 layer is introduced as improvement for ...
