Orchestrated photocatalytic hydrogen generation using surface-adsorbing iridium photosensitizers

26-11-2014 | Yan-Jie Wang; Gang Chang; Qingyun Chen; Guan-Jun Yang; Sheng-Qiang Fan; Baizeng Fang, Chemical Communication, 2014

Novel photosensitizers (PSs) with formyl bipyridyl ligands in different positions were developed to improve the electron transfer from an iridium complex PS to a colloidal platinum catalyst, resulting in much higher turnover numbers than the non-formyl bipyridyl Ir-PS in photocatalytic hydrogen ...

Pt-free solar driven photoelectrochemical hydrogen fuel generation using 1T MoS2 co-catalyst assembled CdS QDs/TiO2 photoelectrode

26-11-2014 | R. Raja; P. Sudhagar; Anitha Devadoss; C. Terashima; L. K. Shrestha; K. Nakata; R. Jayavel; K. Ariga; A. Fujishima, Chemical Communication, 2014

The solar-to-hydrogen generation from the TiO2–CdS–ZnS–MoS2 (TCZM) heterointerface was demonstrated. We found that a Pt-free CdS quantum dot-sensitized TiO2 mesoporous electrode with a metallic-type 1T MoS2 co-catalyst resulted in 0.11 ml cm−2 h−1 H2 fuel generation in unassisted potential mode, ...

Ag–Si artificial microflowers for plasmon-enhanced solar water splitting

25-11-2014 | Chih-Jung Chen; Ming-Guei Chen; Chih Kai Chen; Pin Chieh Wu; Po-Tzu Chen; Mrinmoyee Basu; Shu-Fen Hu; Din Ping Tsai; ..., Chemical Communication, 2014

We prepared Ag–Si microflowers as the photocathode for water splitting through a facile chemical method. The photocurrent and the hydrogen evolution rate of partially Ag particle decorated-Si microwires were enhanced through the synergistic effects of Ag co-catalytic and plasmonic assistance.

The role of MgB12H12 in the hydrogen desorption process of Mg(BH4)2

18-11-2014 | Yigang Yan; Arndt Remhof; Daniel Rentsch; Andreas Zuttel, Chemical Communication, 2014

MgB12H12 has often been considered as the major obstacle for the reversible hydrogen storage in Mg(BH4)2. This communication provide evidence that MgB12H12 phase (monomers) does not exist in the decomposition products of Mg(BH4)2 at 265 to 400°C, and thereby it will not act as a dead end.

Pt-free solar driven photoelectrochemical hydrogen fuel generation using 1T MoS2 co-catalyst assembled CdS QDs/TiO2 photoelectrode

11-11-2014 | Raja Rajendran; Sudhagar Pitchaimuthu; Anitha Devadoss; Chiaki Terashima; Lok Kumar Shrestha; Katsuhiko Ariga; Kazuy ..., Chemical Communication, 2014

The solar to hydrogen generation from TiO2-CdS-ZnS-MoS2 (TCZM) hetrointerface was demonstrated. We found that Pt free CdS quantum dot sensitized TiO2 mesoporous electrode with metallic-type 1T MoS2 co-catalyst resulted 0.11 ml/cm-2h-1 H2 fuel generation under unassisted potential mode, which was ...

Hydrogen induced p-phosphonic acid calix[8]arene controlled growth of Ru, Pt and Pd nanoparticles

11-11-2014 | Wenzhe Zang; Xianjue Chen; Ramiz A. Boulos; Jeremiah Toster; Colin L. Raston, Chemical Communication, 2014

Monodispersed Ru, Pt and Pd nanoparticles with narrow size distributions (2, 12 and 20 nm respectively) have been synthesised via bubbling hydrogen gas into aqueous solutions of the noble metal ions in the presence of p-phosphonic acid calix[8]arene, at room temperature. Molecular modelling of ...

Tuning the selectivity of triplex DNA receptors

04-11-2014 | Haidong Huang; Peter C. Tlatelpa, Chemical Communication, 2014

Effects of hydrogen bonding clamps on the selectivity of triplex DNA receptors were studied. Incorporation of a 5-methyl-2-thiocytosine base to the parallel homopyrimidine region of a triplex receptor enabled selective molecular recognition of an inosine ligand.

Is it possible to achieve a complete desaturation of cycloalkanes promoted by o-benzyne?

04-11-2014 | Francisco Cervantes-Navarro; Abel de Cózar; Fernando P. Cossío; María A. Fernández-Herrera; Gabriel Merino; Israel F ..., Chemical Communication, 2014

The competence between the possible reaction pathways in the reaction of different cycloalkanes and o-benzyne has been computationally explored. Systems able to undergo complete desaturation by consecutive double hydrogen atom transfer reactions are suggested.

Two act as one: unexpected dimers of catechol direct a solid-state [2+2] photodimerization in a six-component hydrogen-bonded assembly

04-11-2014 | Giannis S. Papaefstathiou; Andrew J. Duncan; Len R MacGillivray, Chemical Communication, 2014

We describe hydrogen-bonded dimers of catechol that act collectively as a single template to direct an intermolecular [2+2] photocycloaddition in the solid state. The directed reactivity involves discrete, six-component hydrogen-bonded assemblies and a photoreaction that occurs stereoselectively ...
