Abstract

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.
