摘要

A hybrid system consisting of non-thermal plasma and perovskite-like catalyst is developed and evaluated for the effectiveness in removing. phenol from gas streams. For thermal catalysis, La0.8Sr0.2Mn0.8Cu0.2O3 shows high activity for phenol removal. Further, La0.8Sr0.2Mn0.8Cu0.2O3 is applied for combined plasma catalysis (CPC). The results indicate that phenol removal efficiency with CPC remains 100% at applied voltage range of 13-16 kV. Importantly, secondary pollutants (O-3 and NOx) and energy efficiency can be inhibited and increased, respectively, as CPC is applied. Overall, this study demonstrates that combining non-thermal plasma with perovskite-like catalyst is effective in removing phenol from gas streams.
