Fabrication of microporous layer-free hierarchical gas diffusion electrode as a low Pt-loading PEMFC cathode by direct growth of helical carbon nanofibers

Improving interfacial contact between each component in the proton exchange membrane fuel cell (PEMFC) can lead to a significant increase in power density and Pt utilization. In this work, the junction between the catalyst layer and gas diffusion layer (GDL) is greatly enhanced through direct attachment of helical carbon nanofibers, giving rise to a hierarchical structure within the electrical interconnections. The alternative novel GDL is produced by spraying a thin layer of Pd2C60 precursor on commercial carbon paper, followed by chemical vapor deposition growth resulting in a surface morphology of well-attached nanofibers surrounding the microfibers present in the commercial carbon paper. Subsequent solvothermal deposition of platinum nanoparticles allowed evaluation of its suitability as gas diffusion electrode in cathodic H2/O2 PEMFC environment. A combination of lowered charge transfer resistance and enhanced Pt-utilization is attributed to its unique wire-like appearance and its robust properties. The fabricated microporous layer-free GDL is suitable for relatively aggressive membrane electrode assembly fabrication procedures and is produced by industrially favorable techniques, rendering it capable of efficiently supporting small amounts of precious metal catalyst nanoparticles in various PEM applications.

One-Dimensional Metal Nanostructures: From Colloidal Syntheses to Applications

This Review offers a comprehensive review of the colloidal synthesis, mechanistic understanding, physicochemical properties, and applications of one-dimensional (1D) metal nanostructures. After a brief introduction to the different types of 1D nanostructures, we discuss major concepts and methods typically involved in a colloidal synthesis of 1D metal nanostructures, as well as the current mechanistic understanding of how the nanostructures are formed. We then highlight how experimental studies and computational simulations have expanded our knowledge of how and why 1D metal nanostructures grow. Following specific examples of syntheses for monometallic, multimetallic, and heterostructured systems, we showcase how the unique structure-property relationships of 1D metal nanostructures have enabled a broad spectrum of applications, including sensing, imaging, plasmonics, photonics, display, thermal management, and catalysis. Throughout our discussion, we also offer perspectives with regard to the future directions of development for this class of nanomaterials.

Perfluorinated phosphine and hybrid P-O ligands for Pd catalysed C-C bond forming reactions in solution and on Teflon supports

The synthesis of two types of phosphine ligands that feature perfluorinated ponytails is reported. A bidentate (RfCH2CH2)2PCH2CH2P(CH2CH2Rf)2 (Rf = CF3(CF2)n; n = 5, 7) and an alkoxyphosphine made by ring opening a fluorous epoxide, RfCH2CH(OH)CH2PR2 (Rf = CF3(CF2)7), have been prepared and spectroscopically characterised. The electronic effects of the fluorous chains have been elucidated from either the 1JPt-P or 1JP-Se coupling constants in Pt(ii) or phosphine selenide compounds. Whilst the bidentate phosphines do not give stable or active Pd catalysts, the hybrid ligand does allow Susuki, Heck and Sonogashira catalysis to be demonstrated with low catalyst loadings and good turnovers. Whilst a fluorous extraction methodology does not give good performance, the ligand can be adsorbed onto Teflon tape and for the Suzuki cross coupling reaction the catalytic system can be run 6 times before activity drops and this has been traced to oxidation of the ligand. Additionally the crystal structure of the hybrid phosphine oxide is reported and the non-covalent interactions discussed.

Palladium-Catalyzed Enantioselective Arylation of Aryl Sulfenate Anions: A Combined Experimental and Computational Study

A novel approach to produce chiral diaryl sulfoxides from aryl benzyl sulfoxides and aryl bromides via an enantioselective arylation of aryl sulfenate anions is reported. A (JosiPhos)Pd-based catalyst successfully promotes the asymmetric arylation reaction with good functional group compatibility. A wide range of enantioenriched diaryl, aryl heteroaryl, and even diheteroaryl sulfoxides were generated. Many of the sulfoxides prepared herein would be difficult to prepare via classic enantioselective oxidation of sulfides, including Ph(Ph-d5)SO (90% ee, 95% yield). A DFT-based computational study suggested that chiral induction originates from two primary factors: (i) both a kinetic and a thermodynamic preference for oxidative addition that places the bromide trans to the JosiPhos-diarylphosphine moiety and (ii) Curtin-Hammett-type control over the interconversion between O- and S-bound isomers of palladium sulfenate species following rapid interconversion between re- and si-bound transmetalation products, re/si-Pd-OSPh (re/si-PdO-trans).

Spectroscopic and electrochemical properties of ruthenium complexes with photochromic triarylamine-dithienylethene-acetylide ligands

A new dithienylperfluorocyclopentene-acetylide ligand (L2o) appended with a triarylamine moiety was used to synthesize two ruthenium(ii) complexes with a photoswitchable electronic interaction between inorganic (Ru) and organic (triarylamine) redox centres. The reactions of cis-Ru(dppe)2Cl2 with one or two equiv. of L2o produce trans-Ru(dppe)2(L2o)Cl (1o) or trans-Ru(dppe)2(L2o)2 (2oo), respectively. As demonstrated by 1H and 31P NMR spectral studies, 2oo shows stepwise photocyclization leading first to the singly ring-closed species 2co, and then to the doubly ring-closed species 2cc upon irradiation at 312 nm. Complex 1o exhibits two separated anodic waves at 0.60 (RuII/III) and 0.86 V (N0/+) caused by inherent redox dissymmetry and electronic interaction. Upon conversion to the ring-closed species 1c, three reversible anodic waves are found at 0.28, 0.37 and 0.66 V due to the oxidation of the ring-closed DTE, triarylamine and Ru, respectively. One-electron oxidized species [1c]+ displays broad and moderately intense absorption bands in the near-infrared region induced by charge delocalization. For the oxidized species [2oo]2+/[2co]2+/[2cc]2+, charge delocalization along the molecular backbone shows a progressive increase following the stepwise photocyclization process. Introduction to the international collaboration Zhong-Ning Chen and Denis Jacquemin launch a collaborative research project on multi-photochromism in metal complexes encompassing several photochromic moieties. The group of Chen is devoted to the experimental synthesis and characterization of metal coordinated systems with multi-photochromic dithienylethene (DTE) moieties and the use of stepwise or selective photochromism to modulate switchable electronic communication and charge delocalization in heterometallic or inorganic-organic mixed-valence systems. Jacquemin’s group focuses on theoretical investigation of the mechanism underlying the multi-photochromism through a time dependent density functional theory (TD-DFT) approach, taking into account when necessary spin-orbit couplings (SOC) so as to model potential intersystem crossings (ISC).
