Abstract
The present work was focused on the preliminary stage of palladium composite membrane preparation through electroless plating and the effects of bath hydrodynamic properties on the deposited layer morphology. Eight samples of palladium composite membrane were prepared which were different in terms of plating time, solution stirring rate and bath agitating mode. Scanning electron microscopy and energy-dispersive X-ray spectroscopy were used for characterization of deposited layer. In comparison with the support rotating mode, the support fixing and the magnet rotating mode, which are caused running the solution toward the support, were led to a deposited layer with better quality, larger grains of deposited layer, more compacted plating and higher plating efficiency.
