“…Those involving the breaking of C▬H and C▬C bonds at low temperatures are important. In this sense, cobalt catalysts supported on zirconia, ceria, and alumina have reported high catalytic activity, similar to that obtained with the noble metal [93][94][95][96]. These solids have also been used satisfactorily in the dry-steam reforming process [97] in order to obtain synthesis gas enriched with hydrogen.…”

Metal and metal oxide nanoparticles have attracted increased attention due to their unusual physical and chemical properties. The nature, dispersion, and size of the nanoparticles are key factors in determining the activity and selectivity of the supported catalysts. Supercritical fluid deposition (SCFD) is a promising method to deposit metallic nanoparticles and films on inorganic porous supports. CO 2 is the most commonly used supercritical fluid (sc-CO 2) for material synthesis because it is nontoxic, nonreactive, nonflammable, and inexpensive. This work presents the synthesis of cobalt, nickel, and ruthenium nanoparticles on MCM-41, Al-MCM-41, MCM-48, and activated carbon supports in sc-CO 2. Batch and continuous deposition are studied, with two high-pressure reactor configurations: column or alternative (sandwich). To avoid the length of the bed being too long, the reagents were separated into smaller amounts and placed alternately, keeping the total mass of the precursor and support constant. The prepared samples were characterized by scanning electron (SEM/EDX) and transmission electron microscopy (TEM).

“…Sahoo et al [41] studied the kinetic of ESR over Co/Al2O3. LaNiO3 perovskite [42], Pt1.5Cox/ZrO2 [43] were also used for ESR It should be noted that both H2 and CO can be consumed via electrochemical reaction in SOFC. Normally, a reformer is separated from the fuel cell.…”

Solid Oxide Fuel Cell (SOFC) is typically operated at high temperature. Both electricity and heat are generated during operation. Therefore, SOFC can be efficiently designed to integrate the endothermic reformer with the cell for optimizing heat utilization, as called autothermal operation. However, the mismatch between rate of exothermic electrochemical reaction and endothermic reforming reaction is easily resulted in material cracking of that integrated structure. In order to overcome the thermal mismatch limitation, various approaches for autothermal SOFC configurations have been widely developed; these configurations can be classified into 2 main groups including direct internal reforming (as called DIR-SOFC) and indirect internal reforming (as called IIR-SOFC) operations. This review focuses on the technological progress of these various configurations. In detail, the thermal behavior inside each autothermal SOFC configuration is explored. The effect of different primary hydrocarbon fuels on temperature distribution in the autothermal SOFC structures is also indicted. In addition, the advantage and disadvantage on thermal stress reduction of each configuration are also discussed. The historical of this development would advantage for further system modification and scale up to desired power output

“…(Chiou et al, 2014;Rossetti et al, 2014) In this context, TiO 2 was used as support for Ni, Co, and Cu to prepare catalysts for ESR, characterized by SMSI (Rossetti et al, 2014). According to this, the calcination temperature and in general the preparation procedure for the catalyst are key factors for promoting SMSI.…”
