The Effect of Promoters Added on Ni Supported on Cerium–Zirconia on CO2 Activation and CO Selectivity of the RWGS Reaction
The main challenge for the RWGS reaction’s technological feasibility is the search for catalysts operating at low temperatures for CO2 activation and conversion and preventing secondary reactions, such as methanation. In this work, the metals Copper (Cu), Iron (Fe), Ruthenium (Ru), and Nickel (Ni) catalysts and combined metals on Cerium-Zirconia support were synthesized, characterized, and tested in the RWGS. The Fe–Ni–Cu combination was the most effective at lower temperatures (400 °C) compared to other metallic combinations 2, presenting 40% CO2 conversion (equilibrium conversion is 42%) and high selectivity of 90%, CO as the main product and considerable reduction of by-products.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
