A mixed electrolytic deposit (ED) of PdCu (~20 at.% Cu) is synthesized from a solution of 1 mМ PdSO₄ + 5 mМ CuSO₄ + 0.5 M H₂SO₄ in the region of copper underpotential deposition (+400 mV vs. RHE). The incorporation of copper into the Pd deposit increases its true surface area (S_true) by a factor of ~20 and changes its hydrogen sorption characteristics. The ED PdCu demonstrates higher specific activity in FAOR as compared with individual Pd deposit (Е_dep = 0.4 V). The specific solubility of Pd from ED PdCu is shown to be 2–3 times lower than the solubility of ED Pd; however, its total solubility from PdCu increases due to the strong increase in S_true.

由1mМPdSO ₄  + 5mМCuSO ₄  + 0.5 MH ₂ SO ₄溶液在铜的欠电位沉积区域（+400 mV vs. ）合成PdCu（〜20 at。％Cu）的混合电解沉积物（ED）（RHE）。将铜掺入Pd沉积物中时，其真实表面积（S _true）增大了约20倍，并改变了其氢吸附特性。的ED PDCU在FAOR表明更高的比活性与个别的Pd存款（相比Е _DEP  =  0.4 V）。ED PdCu的Pd的比溶解度比ED Pd的溶解度低2-3倍。但是，由于PdCu的强烈增加，其在PdCu中的总溶解度增加Š_真。
