Direct solvothermal phosphorization of nickel foam to fabricate integrated Ni2P-nanorods/Ni electrodes for efficient electrocatalytic hydrogen evolution

16-Apr-2015 | Xiaoguang Wang; Yury V. Kolen'ko; Lifeng Liu, Chemical Communication, 2015

We report an easy one-step approach for fabricating integrated Ni2P-nanorods/Ni (Ni2P-NRs/Ni) electrodes by direct phosphorization of a commercially available nickel foam current collector under solvothermal conditions. The resulting self-supported Ni2P-NRs/Ni composite electrode exhibits high ...

Towards a methanol economy based on homogeneous catalysis: methanol to H2 and CO2 to methanol

15-Apr-2015 | E. Alberico; M. Nielsen, Chemical Communication, 2015

The possibility to implement both the exhaustive dehydrogenation of aqueous methanol to hydrogen and CO2 and the reverse reaction, the hydrogenation of CO2 to methanol and water, may pave the way to a methanol based economy as part of a promising renewable energy system. Recently, homogeneous ...

Plasma-engineered MoS2 thin-film as an efficient electrocatalyst for hydrogen evolution reaction

15-Apr-2015 | Li Tao; Xidong Duan; Chen Wang; Xiangfeng Duan; Shuangyin Wang, Chemical Communication, 2015

Herein, for the first time, we reported a general approach of plasma engineering to tune the surface properties and edge reactive sites for greatly improving HER (hydrogen evolution) activity of MoS2. We show that the Ar or O2 plasma can be used to generate a large number of physical and chemical ...

A membraneless air-breathing hydrogen biofuel cell based on direct wiring of thermostable enzymes on carbon nanotube electrodes

15-Apr-2015 | Noémie Lalaoui; Anne de Poulpiquet; Raoudha Haddad; Alan Le Goff; Michael Holzinger; Sébastien Gounel; Michel Mermou ..., Chemical Communication, 2015

A biocathode was designed by the modification of a carbon nanotube (CNT) gas-diffusion electrode with bilirubin oxidase from Bacillus pumilus, achieving high current densities up to 3 mA cm−2 for the reduction of O2 from air. A membraneless air-breathing hydrogen biofuel cell was designed by ...

Co3O4 nanocrystals ink printing on carbon fiber paper as large-area electrode for electrochemical water splitting

09-Apr-2015 | Shichao Du; Zhiyu Ren; Jun Zhang; Jun Wu; Wang Xi; Jiaqing Zhu; honggang Fu, Chemical Communication, 2015

A large-area, self-supported Co3O4 nanocrystals/carbon fiber electrode for oxygen and hydrogen evolution reaction was fabricated via thermal decomposition of [Co(NH3)n]2+-oleic acid complex and subsequent spray deposition. Due to the exposed active sites and good electrical conductivity, its ...

Efficient charge separation on 3D architectures of TiO2 mesocrystals packed with a chemically exfoliated MoS2 shell in synergetic hydrogen evolution

08-Apr-2015 | Peng Zhang; Takashi Tachikawa; Mamoru Fujitsuka; Tetsuro Majima, Chemical Communication, 2015

Here we demonstrated that 3D architectures of TiO2 mesocrystals uniformly packed with a chemically exfoliated MoS2 shell exhibit promising reactive efficiency and good stability in synergetic hydrogen evolution. The efficient interfacial electron transfer from the excited TiO2 moieties to the ...

Enhanced CO2 electroreduction efficiency through secondary coordination effects on a pincer iridium catalyst

24-Mar-2015 | Steven T. Ahn; Elizabeth A. Bielinski; Elizabeth M. Lane; Yanqiao Chen; Wesley H. Bernskoetter; Nilay Hazari; G. Tay ..., Chemical Communication, 2015

An iridium(iii) trihydride complex supported by a pincer ligand with a hydrogen bond donor in the secondary coordination sphere promotes the electrocatalytic reduction of CO2 to formate in water/acetonitrile with excellent Faradaic efficiency and low overpotential. Preliminary mechanistic ...

Ethanol induces the formation of water-permeable defects in model bilayers of skin lipids

18-Mar-2015 | R. Thind; D. W. O'Neill; A. Del Regno; R. Notman, Chemical Communication, 2015

We show that ethanol can induce the formation of water-permeable defects in model membranes of skin, providing a fresh perspective on ethanol as a membrane modulator. We rationalise our findings in terms of the chemical nature of ethanol, i.e., a combination of its hydrogen bonding propensity and ...

Conserved hydrogen bonding in tetrahydrocarbazolone derivatives: influence of solution-state assembly on crystal form nucleation

17-Mar-2015 | Robert M. Edkins; Elliott Hayden; Jonathan W. Steed; Katharina Fucke, Chemical Communication, 2015

Two tetrahydocarbazolone derivatives were found to show multiple unsolvated crystal forms. A persistent dimer motif was detected in solution by FTIR spectroscopy that is maintained in the kinetic crystal forms. Rationally introduced steric bulk induces the formation of a more stable catemeric ...

Decoloration rates of a photomerocyanine dye as a visual probe into hydrogen bonding interactions

11-Mar-2015 | Simone Ciampi; Paul K. Eggers; Naomi L. Haworth; Nadim Darwish; Pawel Wagner; Michelle L. Coote; Gordon G. Wallace; ..., Chemical Communication, 2015

We have developed a visual marker for the investigation of hydrogen bonding (HB) effects. The decoloration rate of a photochromic dye that incorporates a latent intra-molecular HB feature can be linked to the HB character of the media. Kinetic and thermodynamic parameters of this simple ...
