| description | <p></p><div> <p>In this study, we explore the effect of nickel incorporation in Cu/fumed-SiO<sub>2</sub> catalyst for CO<sub>2</sub> reduction reaction. Two catalysts, Cu and CuNi supported on fumed silica were synthesized using a novel surface restricted combustion synthesis technique, where the combustion reaction takes place on the surface of the inert fumed-SiO<sub>2</sub> support. An active solution consisting of a known amount of metal nitrate precursors and urea (fuel) was impregnated on fumed silica. The catalyst loading was limited to 1 wt% to ensure localized combustions on the surface of fumed-SiO<sub>2</sub> by restricting the combustion energy density. The synthesized catalysts were tested for CO<sub>2</sub> hydrogenation reaction using a tubular packed bed reactor between temperature 50°C and 650°C, where Cu/SiO<sub>2</sub> showed high CO<sub>2</sub> conversion to carbon monoxide, and the addition of Ni further improved the catalytic performance and showed some tendency for methane formation along with CO. Moreover, both the catalysts were highly stable under the reaction conditions and did not show any sign of deactivation for ~42 hours time on stream (TOS). The catalysts were characterized using X-ray diffractometer (XRD), scanning electron microscope/energy dispersive X-ray spectrometer (SEM/EDX), transmission electron microscope (TEM), and the Brunauer-Emmet-Teller (BET) surface area measurement technique to understand their structural properties and to assess the effect of CO<sub>2</sub> conversion reaction. In situ DRIFTS was also used to investigate the reaction pathway followed on the surface of the catalysts.</p> </div><p></p><h2>Other Information</h2> <p> Published in: International Journal of Energy Research<br> License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="http://dx.doi.org/10.1002/er.6586" target="_blank">http://dx.doi.org/10.1002/er.6586</a></p> |
