A notable achievement was the substantial reduction of ozone-typically 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 CO 2 selectivity and the carbon balance, defined as the CO 2 -to-CO ratio. The application of a TiO 2 sol coating on the glass barrier had a minimal effect on the electrical discharge characteristics. Energy efficiency analysis indicated that energy yield decreased with increasing applied voltage (3 to 4.5 kV), while higher gas flow rates contributed to improved energy yield.
