Plasmonic Au nanoparticles embedding enhances the activity and stability of CdS for photocatalytic hydrogen evolution

13-Jan-2016 | Guiyang Yu; Xiang Wang; Jungang Cao; Shujie Wu; Wenfu Yan; Gang Liu, Chemical Communication, 2016

The activity and stability of CdS for visible-light-driven hydrogen evolution could be significantly enhanced by embedding plasmonic Au nanoparticles. The plasmon resonance energy field of Au nanoparticles could increase the formation rate and lifetime of e−/h+ pairs in CdS semiconductors.

The synergistic effect of a well-defined Au@Pt core–shell nanostructure toward photocatalytic hydrogen generation: interface engineering to improve the Schottky barrier and hydrogen-evolved kinetics

13-Jan-2016 | Sung-Fu Hung; Ya-Chu Yu; Nian-Tzu Suen; Guan-Quan Tzeng; Ching-Wei Tung; Ying-Ya Hsu; Chia-Shuo Hsu; Chung-Kai Chang ..., Chemical Communication, 2016

A well-defined co-catalyst system TiO2 nanotube–Au (core)–Pt (shell) was demonstrated to be the combination of the localized surface plasmon effect of gold and excellent proton reduction nature of platinum. Furthermore, surface engineering by the descending Fermi energies of gold and platinum was ...

Intrinsic magnetic characteristics dependent charge transfer and visible photo-catalytic HER properties of Fe3O4@PPy@Pt catalyst

12-Jan-2016 | Wenyan Zhang; Chao Kong; Wei Gao; Gongxuan Lu, Chemical Communication, 2016

A ternary nano-architectural photocatalyst has been designed to investigate whether the intrinsic magnetic property of photo-catalysts have effect on the charge transfer and its photo-catalytic HER properties under visible light irradiation. The electron transfer and the visible-light-driven ...

Hydrogenated CeO2−xSx mesoporous hollow spheres for enhanced solar driven water oxidation

12-Jan-2016 | Yuting Xiao; Yajie Chen; Ying Xie; Guohui Tian; Shien Guo; Taoran Han; Honggang Fu, Chemical Communication, 2016

A facile route for the fabrication of hydrogenated sulfur-doped CeO2 (H-CeO2−xSx) mesoporous hollow spheres is reported. The spheres exhibited excellent photocatalytic activity due to the synergistic effect of the higher sulfur doping level and hydrogen post-treatment.

Chemically-modified cellulose paper as smart sensor device for colorimetric and optical detection of hydrogen sulfate in water

12-Jan-2016 | Jordi Rull-Barrull; Martin d'Halluin; Erwan Le Grognec; François-Xavier Felpin, Chemical Communication, 2016

A portable, recyclable and highly selective paper-based sensor device for the colorimetric and optical detection of hydrogen sulfate anions in water was developed. The detection system features a rhodamine-based sensor covalently grafted onto the highly hydrophilic surface of cellulose paper.

Surface ligand-directed pair-wise hydrogenation for heterogeneous phase hyperpolarization

30-Dec-2015 | S. Glöggler; A. M. Grunfeld; Y. N. Ertas; J. McCormick; S. Wagner; L.-S. Bouchard, Chemical Communication, 2015

para-Hydrogen induced polarization is a technique of magnetic resonance hyperpolarization utilizing hydrogen's para-spin state for generating signal intensities at magnitudes far greater than state-of-the-art magnets. Platinum nanoparticle-catalysts with cysteine-capping are presented. The ...

A polymorphism-dependent T1/2 shift of 100 K in a hysteretic spin-crossover complex related to differences in intermolecular weak CH[three dots, centered]X hydrogen bonds (X = S vs. S and N)

30-Dec-2015 | Hiroaki Hagiwara; Shohei Okada, Chemical Communication, 2015

A neutral mononuclear iron(ii) complex with a 1,2,3-triazole-containing tetradentate ligand has been obtained as two solvent-free polymorphs. Both polymorphs show hysteretic spin crossover with a polymorphism-dependent T1/2 shift of 100 K that spans room temperature due to differences in ...
