The invention relates to a preparation method of a platinum-nickel alloy supported catalyst. The preparation method comprises the following steps: adding a catalyst carrier into organic solvent for ultrasonic dispersion; then heating to remove the organic solvent; depositing a platinum source and a nickel source on a catalyst carrier by use of an atomic layer deposition method to obtain the platinum-nickel alloy supported catalyst. The invention also relates to the catalyst obtained through the method. According to the method, the dispersity of active components and acting force between the active components and the carrier are improved by use of the atomic layer deposition method, and the cost of the catalyst is reduced as the bimetallic catalyst is prepared by use of nickel-doped platinum. 本发明涉及种铂镍合金负载催化剂的制备方法，将催化剂载体加入到有机溶剂中超声分散，然后加热除去有机溶剂，使用原子层沉积法将铂源和镍源沉积到催化剂载体上，得到铂镍合金负载催化剂。本发明还涉及上述方法得到的催化剂。该方法使用原子层沉积法提高活性组分的分散度、活性组分与载体之间的作用力，并以金属铂掺杂镍制备双金属催化剂降低催化剂的成本。
