Suspension plasma spraying consists in the injection of liquid/nanopowder mixture into a plasma jet. The interest of this technique is to create nano-structured and thin coatings. The porous structure made has a wide specific surface area and is very attractive for catalytic application. This article is devoted to present our works on La0.75Sr0.25Cr0.5Mn0.5Ox doped rhodium deposits used for reforming methane. The first part presents the spraying operation and the second part, the results in term of microstructure and reforming performance.
