Acceptorless dehydrogenation of alcohols using Cu–Fe catalysts prepared from Cu–Fe layered double hydroxides as precursors

Abstract

Cu–Fe catalysts prepared from Cu–Fe layered double hydroxides (LDHs) exhibited high activity for dehydrogenation of alcohols under oxidant- and base-free conditions.

Recent Advances in Carbon Dioxide Adsorption, Activation and Hydrogenation to Methanol using Transition Metal Carbides

“…The catalysts prepared via all three methods (SG, SV, and SS) own very similar carburization mechanisms and physicochemical properties. [175] Despite all these similarities, the catalytic activity of the catalyst differs significantly. The reason behind this was uncovered by examining the population and type of active site available for CO 2 and H 2 activation on the 20 wt % CuÀ Mo 2 C surface via physicochemical characterization and temperature-programmed desorption.…”

“…The reason behind this was uncovered by examining the population and type of active site available for CO 2 and H 2 activation on the 20 wt % CuÀ Mo 2 C surface via physicochemical characterization and temperature-programmed desorption. [175] Clean Mo 2 C has a large number of Moterminated surfaces that have the ability to both dissociate and activate CO 2 and H 2 , respectively. Active sites of the clean Mo 2 C favor the complete dissociation of CO 2 into CO and O moieties and may hydrogenate to methane as well.…”

“…Active sites of the clean Mo 2 C favor the complete dissociation of CO 2 into CO and O moieties and may hydrogenate to methane as well. [175] The presence of Cu on Mo 2 C induces the charge transfer from Cu to Mo 2 C and binds to CO 2 , thus promoting the CO 2 hydrogenation to methanol. This was due to the close interaction between Cu and β-Mo 2 C. [175] Moreover, the catalyst prepared via the solidstate synthetic route has limited active sites due to the extensive carbon deposition on the surface.…”

Environmentally-friendly synthesis of copper(I)-Tricine complex intercalated layered double hydroxide coated magnetite nanocomposites and its application in oxidative esterification by using ultrasonic irradiation

“…Recently, Layered double hydroxide nanosheets have attained signi cant popularity due to their simple preparation, synthesis from earth-abundant elements, eco-friendly, well accessibility, being low cost simple tenability of the chemical material, good thermal stability, broad area, and high structural stability [5][6][7][8][9]. These are known as hydrotalcite like compounds or anionic clay with the common formula of LDH be de ned by [M ions [8,10].…”
