      All at sea: Marine yeasts from deep-sub-seafloor sediments were grown in seawater and used as biocatalysts to perform the stereoselective reduction of different ketones in seawater as well. Strains of Meyerozyma guilliermondii and Rhodotorula mucilaginosa were able to reduce different aromatic ketones with high molar conversions and moderate-to-high enantioselectivity.

      If you know what amine: On the basis of bioinformatic analysis of the binding site of amine transaminases, a seven-site combinatorial library of the enzyme from V. fluvialis is created. High-throughput screening of this library leads to the identification of enzyme variants able to convert sterically demanding ketones into the corresponding chiral amines with high to excellent optical purities and yields.

      Silver lining to water splitting: Light absorption to the wide wavelength range within the visible-light-region is demonstrated with a combination of two different plasmonic metals Ag+Au on TiO2. H2 generation from water splitting or photocurrent generation on Ag on Au-TiO2 increases at least twice that of Ag or Au alone on TiO2.

      Size matters: The encapsulation of surfactant-free Pd nanoparticles in ZIF-8 hollow nanospheres is achieved. Pd@ZIF-8 hollow nanospheres show excellent size-selective catalysis properties in the liquid-phase hydrogenation of olefins. As a result of the uniform pore size of the ZIF-8 shell, the catalyst shows high activity for the hydrogenation of 1-hexene but very low activity for larger molecules such as cis-cyclooctene and trans-stilbene.

      Au hydroamination catalyst: The in situ synthesis of gold nanoparticles in the surface cavity of mesoporous nitrogen-rich carbon (MCN) allowed them to be utilized efficiently as a catalyst in the hydroamination of phenylacetylene with aniline, with more than 98 % selectivity towards the Markovnikov addition product. The mechanistic pathway has been studied with DFT-based calculations, which predict the stabilization of tetranuclear Au clusters over the MCN support.

      C3 selectivity is important: The C3 selectivity of carbon-supported Au nanoparticles for glycerol electro-oxidation is significantly enhanced by the interaction of Au with electrodeposited Cu species. Notably, the C3 selectivity of supported Au nanoparticles doubles after 90 min of Cu electrodeposition at +0.015 V.

    4. Spin Catalysis over Conductive Solids: Enhancing the Rate of Model C−C Bond Cracking over Carbon Nanoparticles

      Spin catalysis: The concept of spin catalysis is illustrated by quantum-chemical calculations for model C−C bond cleavage in ethane. The rate of reaction is shown to be enhanced by allowing normally forbidden spin flip mediated by a spin-conductive half-metallic carbon nanoparticle through a common electronic system, and possible formation of a nascent triplet radical pair that is unable to recombine.

    1. Syndiotactic Polymer of Allylcyclopentane by a Metallocene Catalyst

      Dr. Wei Wang, Dr. Liping Hou and Jianfang Sheng

      Version of Record online: 14 SEP 2016 | DOI: 10.1002/cctc.201600711

      Thumbnail image of graphical abstract

      Shape games: Syndiospecific (co)polymerization of higher α-olefins is performed by using a metallocene catalyst. A copolymer of allylcyclopentane with a linear α-olefin shows weakened syndiotacticity, and the copolymer of allylcyclopentane with 4-methyl-1-pentene or allylcyclohexane keeps the high syndiotacticity. It follows that the monomer employed in copolymerization with a similar “shape” gives the copolymer with a similar microstructure.

      Acid traps sweetener: The interplay of active sites in zeolites is complex. The zeolites function as bifunctional catalysts for Lewis-acid-catalyzed isomerization of glucose to fructose and for Brønsted-acid-catalyzed trapping of fructose as fructosides. This leads to kinetic product control and enables higher than equilibrium yields of fructose to be obtained after hydrolysis.

      Noble metal substitutes: A series of Cu(OH)2–Ni(OH)2/P25 photocatalysts was prepared by co-deposition–precipitation (total metal loading ≈1 wt %) and their performance was evaluated for H2 production. Among this series, the 0.8 Cu(OH)2–0.2 Ni(OH)2/P25 photocatalyst demonstrated very high H2 production rates in 20 vol % ethanol/water and 5 vol % glycerol/water mixtures (10 and 22 mmol h−1 g−1, respectively).

    2. Highly Selective and Stable NiSn/SiO2 Catalyst for Isobutane Dehydrogenation: Effects of Sn Addition

      Dr. Guowei Wang, Dr. Haoren Wang, Huanling Zhang, Dr. Qingqing Zhu, Prof. Chunyi Li and Prof. Honghong Shan

      Version of Record online: 8 SEP 2016 | DOI: 10.1002/cctc.201600685

      Thumbnail image of graphical abstract

      Effectively separated: The promoting mechanism of Sn addition to Ni/SiO2 catalysts was interpreted as a result of geometric and electronic effects. On one hand, Sn addition dispersed aggregated Ni particles effectively, breaking the active sites for hydrogenolysis. On the other hand, additional electrons provided by Sn led to a high electronic density of Ni, facilitating the desorption of isobutene and suppressing secondary reactions.
