Abstract
Spinel-structured catalysts, with flexible frameworks and adjustable compositions, enhance catalytic performance by creating active sites. During CO2 hydrogenation, these catalysts promote CO2 bond cleavage and activation. This paper investigates the performance of the spinel-type catalyst Na/CaFe2O4, achieving a 39.29 % selectivity for light olefins and a conversion rate of 49.72 %. Data analysis showed that adding Ca increased the concentration of strong basic sites and oxygen vacancies in the catalysts, enhancing CO2 conversion. Additionally, Na and Ca facilitated the dissociative adsorption of C-O bonds and subsequent C-C coupling, improving the catalytic efficiency of CO2 hydrogenation. The catalyst demonstrated exceptional stability over 72 h, suggesting its promising industrial applicability.
