Perovskite La0.7Sr0.3Fe0.8Ni0.2O3 associated with D-PHE-MWCNTs for asymmetric electrocarboxylation of acetophenone with CO2

This study investigates the integration of perovskite materials with D-PHE-MWCNTs to synthesize chiral electrodes designed for asymmetric electrocarboxylation of acetophenone with CO2. The D-PHE-MWCNTs demonstrated superior stereoselectivity in asymmetric carboxylation reactions. When integrated with perovskites, known for their CO2 reactivity, there was a notable increase in the yield of 2-hydroxy-2-phenylpropionic acid. By employing diverse synthesis methods, the perovskite materials were enhanced, resulting in an increased surface area and augmented oxygen vacancies crucial for CO2 adsorption and activation. Optimized perovskites with increased surface areas and oxygen vacancies, when integrated with D-PHE-MWCNTs, resulted in an elevated product yield of 74% and a heightened enantiomeric excess value of 84%, highlighting the efficacy of these composite materials in the asymmetric electrocarboxylation of acetophenone with CO2.
