Propagation of Surface Streamers on the Surface of HSY Zeolites-Supported Silver Nanoparticles

The surface-streamer propagation on the surface of a HSY zeolite was measured using a microscope-intensified-charge-coupled-device-camera system. Two different modes of a discharge plasma was observed. Partial-discharge mode only appeared at the onset voltage. As the applied voltage further increased, the surface streamer appeared together with the partial discharge.
