Abstract:In this Letter, electrohydrodynamic atomisation (EHDA) was used to spray deposit Pt/C catalyst films using a Pt/C nanosuspension. In stable cone-jet atomisation mode, the influence of flow rate on the characteristics of relics and films was analysed. At a lower flow rate smaller size and lower number density of relics were predominant, which led to the formation of porous films; conversely, higher flow rate generated dense films. The size of the relics in experimental results and theoretically predicted size were compared and analysed. The dispersive X-ray analysis confirms that the EHDA deposited films are Pt/C.
