Reduction behaviors and catalytic properties for methanol steam reforming of Cu-based spinel compounds CuX2O4 (X=Fe, Mn, Al, La)

Effects of Metal Oxide Support and Non-noble Metal Active Species on Catalytic Steam Reforming of Ethanol for Hydrogen Production

“…It differs principally from the steam reforming of methanol (SRM), which is used in methanol-converting fuel cells, because it involves the cleavage of a C _ C bond. Cu is an excellent catalyst for SRM 8) 10) , but is relatively inactive for SRE because of its poor ability to mediate C _ C bond breaking. In addition, the reaction pathway for SRE is more complicated, and many side reactions may occur 2) .…”

Effect of MnOx in the catalytic stabilization of Co2MnO4 spinel during the ethanol steam reforming reaction

“…Many studies have evaluated the reforming reaction after reducing the catalysts because the metal species were found to be the catalytic active sites during steam reforming. In addition, it was identified also that the activity of the catalyst is dependent on the reduced temperature [27]. TG and H 2 -TPR experiments were conducted to determine the appropriate pre-reduction temperature for the catalysts before ESR, and the curves are displayed in Fig.…”

A solid glycine-based precursor for the preparation of La2CuO4 by combustion method

“…La 2 CuO 4 is known to be an antiferromagnetic Mott insulator (with a Neel temperature NE325 K) [26,27]. It is also an active catalyst of some redox processes taking place in the conversion of nitrogen oxides, carbon oxides and hydrocarbons [5,7,17,18], finds application as a cathode material [28,29] and is used for fabrication of gas sensors [29,30]. In this work, a precursor of La 2 CuO 4 has been synthesized by the interaction of nitrates of lanthanum and copper with glycine in the presence of an aqueous solution of ammonia.…”

“…A step of calcination of the oxide residue left after the combustion is usually required to complete the phase formation process [3][4][5][7][8][9][10][11][12] and decompose the thermodynamically stable phase of lanthanum carbonate [4,5,9,12,16]. Nevertheless, on the whole, the use of organometallic precursors in combustion-based perovskite syntheses shows obvious advantages over the conventional ceramic methods involving time-and energy-consuming steps of sintering (with intermediate steps of grinding) of a mixture of inorganic salts or oxides [17][18][19].…”
