Increasing energy demand needs an alternate source of energy other than fossil fuels. Hydrogen is targeted as the energy source for the next generation due to its environment-friendly applications. However, hydrogen present in lean natural gas, water gas and SMR reaction product has to be separated to get pure hydrogen to be used as fuel. Metallic Palladium/ Palladium alloy tubes of 3 to 5mm thickness are long being used for separating hydrogen from the mixture. Currently, ceramic-supported defect-free Palladium membrane of thickness 2pm to 10pm is the best choice for the preparation of pure hydrogen due to its cost-effectiveness, performance and longevity. In the invention, a non-hazardous, eco-friendly and cheap process of making Palladium membrane is described. Tailor made thickness achieved by this process may also find application in different areas of catalysis.
