Simple low-temperature pulsed power dissociation method for high resistive liquid is proposed in this article. Active high voltage rebound tailing pulse (RTP) diodes are adopted to conventional high voltage pulse power sources. In order to explain this method, the study was performed using deionized water (DIW) (high resistive >17 MΩ⋅>17~\text{M}\Omega \cdot cm) electrolysis with two immersed electrodes. The forward pulses, the full-width at half-maximum (FWHM) of 400 ns and forward voltage (7 kV) with rising-up ratio (dV/dt) of 1011 V/s, were applied to the electrodes. When a 5 kV RTP diode was simply adopted to this electrical circuit and DIW load in series, the high forward voltage pulse and continuous high reverse current were applied to this circuit. Then, H2 was generated at the anode electrode and OH radical (OH) in the water vessel. Those phenomena were apparently dependent on the anode electrode area. At the beginning of the forwarded high voltage application, the circuit behaved as capacitance load with generated ions and built up charges at the interface between DIW and the electrode. Continuous rebounded high reverse voltage and highly built-up reverse recovery charges induce avalanche breakdown of RTP diode. The rebounded electrical current was found to be collected in the circuit, accompanied by the generation of hydrogen and OH, as well as the tailing current flowing at the interface as a resistive load. In consequence, we point out that rebounded electrons injected from the surrounding water to the anode electrode interface induced the water electrolysis characteristically, according to RTP-diode inserted in the circuit.

用于水离解的回弹拖尾脉冲 (RTP) 的新方法


本文提出了一种简单的高阻液体低温脉冲功率解离方法。传统高压脉冲电源采用有源高压回弹拖尾脉冲（RTP）二极管。为了解释该方法，本研究使用去离子水（DIW）（高电阻 >17 MΩ⋅>17~\text{M}\Omega \cdot cm）和两个浸入式电极进行电解。将半峰全宽 (FWHM) 为 400 ns 的正向脉冲和上升比 (dV/dt) 为 1011 V/s 的正向电压 (7 kV) 施加到电极。当该电路简单地采用5 kV RTP二极管和串联DIW负载时，该电路会受到高正向电压脉冲和连续高反向电流的影响。然后，在阳极处产生H2，并在水容器中产生OH自由基(OH)。这些现象显然取决于阳极电极面积。在正向高压应用开始时，电路表现为电容负载，在 DIW 和电极之间的界面处产生离子和累积电荷。持续反弹的高反向电压和高度累积的反向恢复电荷会导致 RTP 二极管雪崩击穿。发现反弹的电流被收集在电路中，伴随着氢气和·OH的产生，以及作为电阻负载在界面处流动的拖尾电流。因此，我们指出，根据电路中插入的 RTP 二极管，从周围的水注入阳极电极界面的反弹电子会引起水电解。
