  • A critical and systematic review of sustainable hydrogen production . . .
    In the ethanol steam reforming, non-noble metals (Co and Ni) are more reactive than noble metals (Rh and Ru) However, the sequence of hydrogen selectivity is featured by Rh > Ir > Ru > Pt > Ni > Co in autothermal reforming of ethanol A high hydrogen yield at a low cost is desired in a successful booming hydrogen economy This necessitates
  • Steam reforming of ethanol for hydrogen production: influence of . . .
    Ethanol steam reforming was studied over Ni supported catalysts The effects of support (Al2O3, Al2O3–ZnO, and Al2O3–CeO2), metal loading, catalyst activation method, and steam-to-ethanol molar feed ratio were investigated The properties of catalysts were studied by N2 physisorption, TPD-CO2, X-ray diffraction, and temperature programmed reduction After activity tests, the catalysts were
  • Hydrogen Production Via Ethanol Steam Reforming Over Ni Al
    Catalytic systems play an important role in hydrogen production via ethanol reforming The effect of Ni loading on the characteristics and activities of Ni Al2O3 catalysts used in pure ethanol steam reforming are not well-understood Two series of catalysts with various Ni loadings (6, 8, 10, 12, and 20 wt %) were prepared by impregnation (IMP) and precipitation (PT) methods and were tested
  • Steam Reforming of Ethanol: Production of Renewable Hydrogen
    3 Catalysts for Ethanol Steam Reforming ESR was reported over noble metals (Pt,Pd,Rh,Ru), non noble metals (Ir,Cu,Co,Ni), metal oxides, mixed metal oxides, hydrotalcite, spinel and perovskite catalysts as summarized at a glance in Table 1 Among non-noble metal catalyst Cu, Ni, Ir and Co
  • Steam reforming of methanol, ethanol and glycerol over nickel-based . . .
    Catalyst shows good activity in terms of higher methanol conversion and hydrogen yield after Ni incorporation The reaction was carried out in the temperature range of 200–400 °C Metal catalysts play an important role on ethanol conversion and hydrogen production in ethanol steam reforming (ESR) Both noble (Rh, Ru, Pt, Pd, Ir, La) and
  • Ethanol steam reforming over Ni ZSM-5 nanosheet for hydrogen production . . .
    Both noble metals (such as Pt and Rh [6, 7]) and transition metals such as (Ni and Co [8, 9]) are active for ESR Comparatively, transition metals are desirable due to their low cost and among these Ni-based catalysts are particularly attractive and common reforming catalysts, which are widely used for ESR due to their ability of cleaving C–C, C–H and C–O bond
  • A review on reforming bio-ethanol for hydrogen production
    Aside from noble metals, Ni is so far the best choice for hydrogen production by catalytic steam reforming of ethanol Ni has high activity for C–C bond and O–H bond breaking and also has high activity for hydrogenation, facilitating H atoms to form molecular H 2 Addition of alkali species could modify the interaction between adsorbed
  • Hydrogen production from ethanol reforming: Catalysts and reaction . . .
    Cu is also more active in methane steam reforming to increase hydrogen yield The promoting effect of noble metals contained both a decrease in the NiO reduction temperature because of the hydrogen spillover and the stabilization of metallic Ni sites along the reaction process [110], [111]
  • A review on ethanol steam reforming for hydrogen production over Ni . . .
    Hydrogen is contemplated as an alternative clean fuel for the future Ethanol steam reforming (ESR) is a carbon-neutral, sustainable, green hydrogen production method Low cost Ni Al 2 O 3 and Ni CeO 2 powder catalysts demonstrate high ESR activity However, acidic nature of Al 2 O 3 and instability of CeO 2 lead to deactivation of the catalysts easily This article examines the research
  • Hydrogen production by steam reforming of ethanol over Ni-based . . .
    The catalytic activity of Ni La 2 O 3-Al 2 O 3 catalysts modified with noble metals (Pt and Pd) was investigated in the steam reforming of ethanol The catalysts were characterized by ICP, S BET, X-ray diffraction, temperature-programmed reduction, UV–vis diffuse reflectance spectroscopy and X-ray absorption fine structure (XANES) The results showed that the formation of inactive nickel
  • Hydrogen production by ethanol steam reforming over multimetallic . . .
    Transition and noble metals as Ni, Rh, Pt, have been studied as active catalyst for ethanol steam reforming and various oxides as Al 2 O 3, MgO, ZrO 2 or CeO 2 are employed as supports [11] Rh addition to conventional Ni-based catalysts is regarded as active system due to its high activity and its capacity to diminish the intermediate products [10]
  • A critical and systematic review of sustainable hydrogen production . . .
    In the ethanol steam reforming, non-noble metals (Co and Ni) are more reactive than noble metals (Rh and Ru) However, the sequence of hydrogen selectivity is featured by Rh > Ir > Ru > Pt > Ni > Co in autothermal reforming of ethanol A high hydrogen yield at a low cost is desired in a successful booming hydrogen economy This necessitates
