Paper Abstract

A hollow electrode fast flow oxygen RF discharge was examined experimentally as an alternative source of molecular singlet delta oxygen. The relative yield of singlet delta oxygen was measured under the following experimental conditions: the RF frequency 13.66 MHz, the RF power up to 500 W, the oxygen output pressure 0.5 - 2.5 Torr, the oxygen flow rate 0.1 - 2.5 Nl/min, the hollow electrode inner diameter 1 - 4 mm, the hollow electrode length 1 - 4 mm, the gas composition--99.5% and 99.995% oxygen, respectively. The singlet delta oxygen yield was increasing with the RF power and decreasing with the pressure. The dependence of the yield on the flow rate and the geometrical dimensions was not monotonous and exhibited an optimum. In such cases, the singlet delta oxygen yield up to 16% was achieved.
