Bimetallic layered double oxide (LDO) NiM (M = Cr, Fe) catalysts with nominal compositions of Ni/M 2 or 3 were tailored from hydroxides (LDH) using a coprecipitation method to investigate the effects trivalent metal (Cr and amount Ni species on structural, textural, reducibility, catalytic properties for CH4/CO2 reforming. The solids before after thermal treatment at 500 °C characterized TGA-TD...
The estimated diffusion fluxes of methane (CH4) and carbon dioxide (CO2) at the sediment-water interface in the Rzeszów Reservoir in southeastern Poland are presented. The relevant studies were conducted during 2009, 2010, and 2011. Calculated fluxes ranged from 0.01 to 2.19 mmol m-2 day-1 and from 0.36 to 45.33 mmol m-2 day-1 for methane and carbon dioxide, respectively. While the values for c...
The three carbon gases carbon monoxide (CO), carbon dioxide (CO2), and methane (CH4) are important atmospheric constituents affecting air quality and climate. The near-infrared nadir spectra measured by SCIAMACHY on ENVISAT contain information on the vertical columns of these gases which we retrieve using a modified DOAS algorithm (WFM-DOAS or WFMD). Our main data products are CO vertical colum...
Hydrogen production from dry reforming of methane (DRM) over chief Ni-based catalyst is cutting edge research area due to environmental consciousness about reducing global warming gases (CH4 and CO2) greener route synthesis. Herein, ceria promoted lanthanum-zirconia supported Ni system (5NixCe/LaZr; x = 0, 1, 1.5, 2, 2.5, 3, 5 wt.%) prepared by the wet impregnation method. It further characteri...
The evolution of the constituents an 8 wt%Ni-5 wt%Fe/MgAl2O4 catalyst for dry reforming methane (DRM) is monitored by in situ quick X-ray absorption spectroscopy (QXAS) and 57Fe Mössbauer spectroscopy. In as prepared state, Fe present NiFe2O4 at surface MgFe3+xAl2?xO4 within support, whereas Ni mainly NiO. During H2-TPR, NiO form alloy from 500 °C on partially reduced to MgFe2+xAl2?xO4, such th...
