Abstract

The invention relates to a platinum nanoparticle coating and a preparation method thereof, and the preparation method comprises the following steps: carrying out cleaning and drying pretreatment on a pre-selected substrate; dissolving a platinum salt in an organic solvent to obtain a platinum precursor solution with a predetermined concentration; adding a surfactant into deionized water, uniformly stirring to obtain an active agent solution with a predetermined concentration, adding the active agent solution into the platinum precursor solution, and reacting at 50-90 DEG C for 1-3 hours to obtain a platinum nanoparticle solution; and immersing the pretreated substrate in a platinum nanoparticle solution, carrying out dip coating at a dip speed of 1-5 mm / s at a coating temperature of 20-60 DEG C, and drying in a nitrogen atmosphere to obtain the platinum nanoparticle coating. According to the preparation method, the platinum nanoparticles with uniform particle size and good dispersity can be prepared by controlling the reaction conditions and the types of the surfactants, and the coating is prepared by adopting a dip coating method, so that the adhesive force and uniformity of the coating can be improved.
