Enhanced VOC Abatement in Indoor Air: Synergistic Hybrid Reactor of Low Voltage DBD Plasma/UV-Photocatalyst for MEK Decomposition
https://doi.org/10.1007/s11814-025-00593-z
Abstract
This study presents the development and performance evaluation of a novel hybrid reactor integrating a UV-photocatalyst
with dielectric barrier discharge (DBD) plasma for the abatement of volatile organic compounds (VOCs) in indoor air,
with a specific focus on methyl ethyl ketone (MEK). A notable achievement was the substantial reduction of ozonetypically
a major byproduct of DBD systems-through the synergistic interaction with the UV-photocatalyst. Compared to
individual UV-photocatalyst or DBD plasma units, the hybrid configuration exhibited a significantly enhanced reaction
rate constant across varying inlet MEK concentrations. However, Conversely, increasing the inlet gas concentration led to
reductions in both CO2 selectivity and the carbon balance, defined as the CO2-to-CO ratio. The application of a TiO2 sol
coating on the glass barrier had a minimal effect on the electrical discharge characteristics. The energy efficiency analysis
based on specific energy density (SED) and energy yield raised the necessity of identifying optimal operating conditions,
particularly in relation to applied voltage and gas flow rate.
