Enhancing CO2 conversion in a temperature-controlled DBD plasma reactor with HKUST-1 catalyst: Water removal and CuO/Cu2O-derived approach
Year: 2024
Type: article
Abstract: Due to synergy effect, using dielectric barrier discharge (DBD) plasma technology combined with catalysts for CO2 decomposition is recognized as an effective approach to transforming CO2 into valuable products. Herein, the HKUST-1 is synthesized using the hydrothermal method for CO2 conversion in the DBD reactor. Since the recombination reaction in the CO2 conversion is increased at higher temperatures, the reactor heat is removed using fan cooling and a water circulation system. The catalysts have been characterized using a comprehensive suite of analytical techniques, including FTIR, XRD, SEM, EDS, and BET analysis. The BET analysis indicates that the specific surface area of HKUST-1 after O2 plasma treatment is increased by 52%, which causes an increasing conversion rate of up to 18%. The CuO/Cu2O catalyst is synthesized through the thermal decomposition of the MOF at 300 ℃. This process results in oxygen vacancies that facilitate a maximum CO2 conversion rate of 21%.
