A versatile, highly scalable single step method is provided for depositing a metallic Pd film from low temperature combustion of an aqueous solution. By using only palladium nitrate and glycine as precursors, water as a solvent, mirror-bright dense Pd films with high crystallinity and good adhesion can be deposited at 250 C. on different substrates without subsequent annealing. The technique can be used to form a reusable catalytic flask as illustrated by the Suzuki-Miyaura cross-coupling reaction, where the Pd film uniformly covers the inner walls of the flask and eliminates the catalyst separation step.
