Production of Dimethylfuran from Hydroxymethylfurfural through Catalytic Transfer Hydrogenation with Ruthenium Supported on Carbon
TL;DR: Transmission hydrogenation using alcohols as hydrogen donors and supported ruthenium catalysts results in the selective conversion of hydroxymethylfurfural to dimethylfuran (>80% yield).
Journal ArticleDOI
Molecular structure, morphology and growth mechanisms and rates of 5-hydroxymethyl furfural (HMF) derived humins
George Tsilomelekis,Michael J. Orella,Zhexi Lin,Ziwei Cheng,Weiqing Zheng,Vladimiros Nikolakis,Dionisios G. Vlachos +6 more
TL;DR: In this paper, the authors apply ATR-FTIR spectroscopy, Scanning Electron Microscopy (SEM) and Dynamic Light Scattering (DLS) experiments to investigate the molecular structure, morphology and growth mechanism of 5-hydroxymethyl furfural (HMF) derived humins as a function of HMF conversion.
Journal ArticleDOI
Experimental and theoretical investigation of molybdenum carbide and nitride as catalysts for ammonia decomposition.

TL;DR: The relatively high rate of reaction observed for the catalytic decomposition of NH3 is ascribed to highly energetic sites (twin boundaries, stacking faults, steps, and defects) which are observed in both the molybdenum carbide and nitride samples, resulting in a much higher H2 production rate in comparison with that for previously reported Mo-based catalysts.
Journal ArticleDOI
Individual Fe-Co alloy nanoparticles on carbon nanotubes: structural and catalytic properties.
TL;DR: The alloy nanoparticles with widely varying Co/Fe ratio are kept as active as Co for the H 2 production from NH 3 decomposition and the stability of Co was significantly improved by alloying with Fe.
Journal ArticleDOI
Effects of CeO2 addition on Ni/Al2O3 catalysts for the reaction of ammonia decomposition to hydrogen
TL;DR: In this article, the authors showed that the addition of CeO 2 enlarged the catalyst pores, moderated the interaction between Ni and alumnia, suppressed Ni 0 crystallites from sintering, and improved the recombinative desorption of N adatoms from the Ni 0 surface.
