One-Step Synthesis of Self-Supported Nickel Phosphide Nanosheet Array Cathodes for Efficient Electrocatalytic Hydrogen Generation.
TL;DR: A convenient and straightforward approach to the synthesis of a three-dimensional (3D) self-supported biphasic Ni5 P4 -Ni2 P nanosheet (NS) array cathode is presented, which is obtained by direct phosphorization of commercially available nickel foam using phosphorus vapor.
Journal ArticleDOI
Pd−Ga Intermetallic Compounds as Highly Selective Semihydrogenation Catalysts
TL;DR: The intermetallic compounds Pd(3)Ga(7), PdGa, and Pd (2)Ga are found to be highly selective semihydrogenation catalysts for acetylene outperforming established systems.
Journal ArticleDOI
Al13Fe4 as a low-cost alternative for palladium in heterogeneous hydrogenation
Marc Armbrüster,Kirill Kovnir,Matthias Friedrich,Detre Teschner,Gregor Wowsnick,M. Hahne,Peter Gille,László Szentmiklósi,Michael Feuerbacher,Marc Heggen,Frank Girgsdies,Dirk Rosenthal,Robert Schlögl,Yuri Grin +13 more
TL;DR: This work has identified the low-cost and environmentally benign intermetallic compound Al(13)Fe(4) as an active and selective semi-hydrogenation catalyst, which might prove applicable to a wide range of heterogeneously catalysed reactions.
Journal ArticleDOI
Hydrothermal synthesis and characterization of nanorods of various titanates and titanium dioxide
Yury V. Kolen'ko,Kirill Kovnir,A. I. Gavrilov,Alexei V. Garshev,Johannes Frantti,Oleg I. Lebedev,Bulat R. Churagulov,Gustaaf Van Tendeloo,Masahiro Yoshimura +8 more
TL;DR: The formation process of titania based nanorod during hydrothermal synthesis starting from an amorphous TiO2.nH2O gel has been investigated and structural defects of the synthesized nanorods were investigated by high-resolution electron microscope.
Journal ArticleDOI
Palladium-Gallium Intermetallic Compounds for the Selective Hydrogenation of Acetylene: Part II: Surface Characterization and Catalytic Performance
Jürgen Osswald,Kirill Kovnir,Marc Armbrüster,Rainer Giedigkeit,Rolf E. Jentoft,Ute Wild,Yuri Grin,Robert Schlögl +7 more
TL;DR: In this paper, the performance of PdGa and Pd3Ga7 was investigated under different acetylene hydrogenation reaction conditions, in absence and in excess of ethylene, in temperature-programmed and isothermal long-term experiments.
