    Hydrogen Production via Ethanol Decomposition over Bimetallic Catalyst حسب Ashok, Anchu

    منشور في 2016
    "…Ethanol decomposition over bimetallic CuCo were conducted using in situ diffuse reflectance infrared fourier transform spectroscopy (DRIFT) study under N2 flow at different temperatures (50, 100, 200, 300, 400°C). Temperature-time profile of CuCo shows an increase in combustion temperature with increase in fuel ratio with maximum temperature at φ = 1 (stoichiometric ratio) and after that it decreases. …"
