| description | <p dir="ltr">This work investigates the effects of solution combustion synthesis (SCS) variables on the performance of copper-based catalysts for CO<sub>2</sub> hydrogenation to methanol. The catalyst with a composition of 30wt%CuO50%ZnO/Al<sub>2</sub>O<sub>3</sub> was prepared at various glycine to nitrates (G/O) ratios in the range between 0.1 and 1.23. A correlation of the effects of calcination and activation temperatures with catalytic activity was also studied. The catalyst synthesized at a G/O ratio of 0.206, calcined in air at 400 °C and activated in a stream of pure hydrogen at a temperature of 350 °C resulted in a significant improvement in the performance of the catalyst for CO<sub>2</sub> hydrogenation. The exceptionally high catalytic performance of the catalyst was attributed to the synergic effects between small well-dispersed CuO nanoparticles and high number of induced copper phases. The highest activity of the catalyst was recorded at an operating temperature of 300 °C, a pressure of 85 bar and GHSV of 7000 h<sup>−1</sup>. The CO<sub>2</sub> conversion, CO selectivity and methanol selectivity under these conditions were 30%, 38.60%, and 61.4%, respectively; whereas, methanol and CO yields were 0.52gMeOH/g-cat.h and 0.33gCO/g-cat.h, respectively.</p><h2>Other Information</h2><p dir="ltr">Published in: Catalysis Communications<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="https://dx.doi.org/10.1016/j.catcom.2022.106543" target="_blank">https://dx.doi.org/10.1016/j.catcom.2022.106543</a></p> |
