We report a simple method for the fabrication of agglomerated Ag–Pd nanocomposites by the addition of NaBH4. The agglomerated Ag–Pd nanocomposites are characterized SEM, TEM, XRD and XPS measurements. The prepared Ag–Pd nanocomposites exhibited catalytic activity in hydrogen generation from decomposition of formic acid at room temperature (∼25 °C). Herein, the present Ag–Pd catalysts possess the new type of agglomerated structure against to dispersion, which make them easily separated from the reaction system. It is convenient for operator to cease catalytic reaction at any moment. Moreover, the resulting Ag–Pd catalysts can be easily reactivated simply by drying after water cleaning for reuse, which saved the cost of catalysts. Among them, Ag1Pd3 sample showed nice performance of recycle test and long lifetime for the decomposition of formic acid at room temperature. We hope that this work opens a new avenue to develop solid catalysts for hydrogen production from formic acid decomposition in solution.
