Mesoporous Co-CeO2 catalyst prepared by colloidal solution combustion method for reverse water-gas shift reaction 10.1016/j.cattod.2018.04.015 2018-04-11 A series of mesoporous Co-CeO2 catalysts with different Co contents were prepared with a colloidal solution combustion method and used for the reverse water-gas shift reaction. Characterizations demonstrate that the Co-CeO2 catalysts have uniform mesoporous s...
Titanium-substituted ferrite perovskite: An excellent sulfur and coking tolerant anode catalyst for SOFCs 10.1016/j.cattod.2018.04.023 2018-04-11 Efficient and direct utilization of hydrocarbon fuel in a solid oxide fuel cell (SOFCs) is highly desirable. However, the carbon deposition and contaminants poisoning issue should be overcome. In this work, we developed a titanium-doped (La,Sr)FeO3 ceramic ox...
Short time synthesis of titania modified-CMK-3 carbon mesostructure as support for Ir-catalyst applied in catalytic hydrotreating 10.1016/j.cattod.2018.04.012 2018-04-09 Ti-CMK-3 carbon mesoporous was prepared using a novel synthesis method. This new method avoids the hard template synthesis used commonly. The method developed here, allows to reduce time, energy consumptionand cost. Structural and textural characterization of...
Theoretical Insights into Direct Methane to Methanol Conversion over Supported Dicopper Oxo Nanoclusters 10.1016/j.cattod.2018.03.063 2018-04-08 The prospect of using copper oxide nanoclusters grown by atomic layer deposition on a porphyrin support for selective oxidation of methane to methanol was examined by means of density functional theory (DFT) calculations. Ab initio thermodynamic analysis indi...
Effect of gold loading on ceria-zirconia support in total oxidation of VOCs 10.1016/j.cattod.2018.04.005 2018-04-07 0.20, 0.37, 0.83, 1.55 and 3.35 wt. % of gold was impregnated on Ce0.5Zr0.5O2 prepared by sol-gel method. Systematic characterizations of gold catalysts by atomic emission spectroscopy, N2 physisorption, X-ray powder diffraction, H2 chemisorption, transmissio...
Graphitic Carbon Nitride Nanosheet Wrapped Mesoporous Titanium Dioxide for Enhanced Photoelectrocatalytic Water Splitting 10.1016/j.cattod.2018.04.007 2018-04-06 We report a new strategy to fabricate a core-shell TiO2@g-C3N4 composite for photoelectrochemical water splitting. The heterojunction structure is prepared by chemically wrapping exfoliated thin layer g-C3N4 nanosheets on the surface of anatase TiO2 particles...
Synthesis of 2,5-diformylfuran from 5-hydroxymethylfurfural in ethyl acetate using 4-acetamido-TEMPO as a recyclable catalyst 10.1016/j.cattod.2018.03.054 2018-04-05 2,5-Diformylfuran (2,5-DFF) is an important furan-based chemical with broad application potential. To address the difficulties in isolating/purifying the product and recycling the 2,2,6,6- tetramethylpiperidine-1-oxy (TEMPO)-based catalysts, we employed a sol...
Partial oxidation of methane to syngas using Co/Mg and Co/Mg-Al oxide supported catalysts 10.1016/j.cattod.2018.04.003 2018-04-03 Partial oxidation of methane (POM) was studied over a series of Co/Mg-Al catalysts. Various commercial hydroxides with different Mg/Al ratios were used as precursors of the oxides employed as catalytic supports, as well as MgO prepared in the laboratory. The ...
Improving CO2 electroreduction over ZIF-derived carbon doped with Fe-N sites by an additional ammonia treatment 10.1016/j.cattod.2018.03.062 2018-04-03 Iron-nitrogen-carbon (Fe-N-C) composite materials show considerable Faradaic efficiency for CO production in electrochemical CO2 reduction reaction (CO2RR), which are promising alternatives to noble metal catalysts. However, reported results exhibit limited C...
The carbonylation of dimethyl ether catalyzed by supported heteropoly acids: The role of Brønsted acid properties 10.1016/j.cattod.2018.04.001 2018-04-03 The carbonylation of dimethyl ether (DME) to methyl acetate (MA) is a vital step in a direct route of ethanol production from syngas. Heteropoly acids (HPAs) as a kind of solid acid catalysts can facilitate the reaction. To improve the accessibility of Brønst...
