Top‐Down and Bottom‐Up Approaches in Engineering 1 T Phase Molybdenum Disulfide (MoS2): Towards Highly Catalytically Active Materials
Chemistry - A European Journal - Tập 22 Số 40 - Trang 14336-14341 - 2016
Chun Kiang Chua, Adeline Huiling Loo, Martin Pumera
AbstractThe metallic 1 T phase of MoS2 has been widely identified to be responsible for the improved performances of MoS2 in applications including hydrogen evolution reactions and electrochemical supercapacitors. To this aim, various synthetic methods have been reported to obtain 1 T phase‐rich MoS2. H...... hiện toàn bộ
Self‐Templating Construction of Hollow Amorphous CoMoS4 Nanotube Array towards Efficient Hydrogen Evolution Electrocatalysis at Neutral pH
Chemistry - A European Journal - Tập 23 Số 52 - Trang 12718-12723 - 2017
Weiyi Wang, Xiang Ren, Shuai Hao, Zhiang Liu, Fengyu Xie, Yadong Yao, Abdullah M. Asiri, Liang Chen, Xuping Sun
AbstractEnvironmentally friendly electrochemical hydrogen production needs the development of earth‐abundant catalyst materials for the hydrogen evolution reaction with high activity and durability at neutral pH. In this work, the self‐templating construction of a hollow amorphous CoMoS4 nanotube array on carbon cloth (CoMoS4... hiện toàn bộ
Unprecedented Living Olefin Polymerization Derived from an Attractive Interaction between a Ligand and a Growing Polymer Chain
Chemistry - A European Journal - Tập 9 Số 11 - Trang 2396-2403 - 2003
Makoto Mitani, Takashi Nakano, Terunori Fujita
AbstractTi complexes incorporating fluorine‐containing phenoxy–imine chelate ligands (fluorinated Ti‐FI catalysts) have been demonstrated to induce an unprecedented living polymerization effect with both ethylene and propylene, through an attractive interaction between the fluorine atom in the ligand and a β‐hydrogen atom on the growing p...... hiện toàn bộ
Fluorescent Sulphur‐ and Nitrogen‐Containing Porous Polymers with Tuneable Donor–Acceptor Domains for Light‐Driven Hydrogen Evolution
Chemistry - A European Journal - Tập 24 Số 46 - Trang 11916-11921 - 2018
Dana Schwarz, Amitava Acharja, Arun Ichangi, Pengbo Lyu, Maksym Opanasenko, Fabian R. Goßler, Tobias A. F. König, Jiřı́ Čejka, Petr Nachtigall, Arne Thomas, Michael J. Bojdys
AbstractLight‐driven water splitting is a potential source of abundant, clean energy, yet efficient charge‐separation and size and position of the bandgap in heterogeneous photocatalysts are challenging to predict and design. Synthetic attempts to tune the bandgap of polymer photocatalysts classically rely on variations of the sizes of their π‐conjugated domains. H...... hiện toàn bộ
Synthesis, Structure, Spectroscopic, and Electrochemical Properties of Highly Fluorescent Phosphorus(V)–meso‐Triarylcorroles
Chemistry - A European Journal - Tập 18 Số 20 - Trang 6386-6396 - 2012
Avijit Ghosh, Mangalampalli Ravikanth
AbstractThe synthesis, spectroscopic, and electrochemical properties of seven new PV–meso‐triarylcorroles (1–7) are reported. Compounds 1–7 were prepared by heating the corresponding free‐base corroles with POCl3... hiện toàn bộ
Aura of Corroles
Chemistry - A European Journal - Tập 15 Số 34 - Trang 8382-8394 - 2009
Iris Aviv‐Harel, Zeev Gross
AbstractCorroles display distinctive structural, spectroscopic, and photophysical properties, as well as some exceptional chemical reactivities that are not shared by other molecules. In addition, low‐valent metal complexes are extremely reactive when chelated by corroles and the opposite holds for the high‐valent counterparts. One aim of this account is to provide...... hiện toàn bộ
Ru‐Catalyzed Branched versus Linear Selective C3‐Alkylation of 2‐Aroylbenzofurans with Acrylates via CH Activation
Chemistry - A European Journal - Tập 20 Số 26 - Trang 7884-7889 - 2014
Yadagiri Kommagalla, Kolluru Srinivas, Chepuri V. Ramana
AbstractThe carbonyl‐directed C3H activation and alkylation of 2‐aroylbenzo[b]furans with acrylates occurs selectively either in a linear or branched fashion, depending on the catalyst employed; [Ru(p‐cymene)Cl2]2 or Ru(PPh3)3Cl...... hiện toàn bộ
Tailored Band Gaps in Sulfur‐ and Nitrogen‐Containing Porous Donor–Acceptor Polymers
Chemistry - A European Journal - Tập 23 Số 53 - Trang 13023-13027 - 2017
Dana Schwarz, Yaroslav S. Kochergin, Amitava Acharjya, Arun Ichangi, Maksym Opanasenko, Jiřı́ Čejka, Uwe Lappan, Pál Árki, Junjie He, Johannes Schmidt, Petr Nachtigall, Arne Thomas, Ján Tarábek, Michael J. Bojdys
AbstractDonor–acceptor dyads hold the key to tuning of electrochemical properties and enhanced mobility of charge carriers, yet their incorporation into a heterogeneous polymer network proves difficulty owing to the fundamentally different chemistry of the donor and acceptor subunits. A family of sulfur‐ and nitrogen‐containing porous polymers (SNPs) are obtained v...... hiện toàn bộ
Recent Advances in the Chemistry and Biology of Podophyllotoxins
Chemistry - A European Journal - Tập 23 Số 19 - Trang 4467-4526 - 2017
Yu Xiang, Zhiping Che, Hui Xu
AbstractPodophyllotoxin and its related aryltetralin cyclolignans belong to a family of important products that exhibit various biological properties (e.g., cytotoxic, insecticidal, antifungal, antiviral, anti‐inflammatory, neurotoxic, immunosuppressive, antirheumatic, antioxidative, antispasmogenic, and hypolipidemic activities). This Review provides a survey of p...... hiện toàn bộ
Interstitial Zn Atoms Do the Trick in Thermoelectric Zinc Antimonide, Zn4Sb3: A Combined Maximum Entropy Method X‐ray Electron Density and Ab Initio Electronic Structure Study
Chemistry - A European Journal - Tập 10 Số 16 - Trang 3861-3870 - 2004
Fausto Cargnoni, Eiji Nishibori, Philippe Rabiller, Luca Bertini, G. Jeffrey Snyder, Mogens Christensen, Carlo Gatti, Bo B. Iversen
AbstractThe experimental electron density of the high‐performance thermoelectric material Zn4Sb3has been determined by maximum entropy (MEM) analysis of short‐wavelength synchrotron powder diffraction data. These data are found to be more accurate than conventional single‐crystal data due to the reduction of common systemat...... hiện toàn bộ
