Facile synthesis of agglomerated Ag-Pd bimetallic dendrites with performance for hydrogen generation from formic acid

We report a simple method for the fabrication of agglomerated Ag-Pd bimetallic dendrites by the addition of NaCOOH. The agglomerated Ag-Pd bimetallic dendrites are characterized SEM, TEM, XRD and XPS measurements. The prepared Ag-Pd bimetallic dendrites exhibited catalytic activity in hydrogen generation from decomposition of formic acid at room temperature (similar to 25 degrees C). Herein, the present Ag-Pd bimetallic dendrites 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 bimetallic dendrites can be easily reactivated simply by drying after water cleaning for reuse, which saved the cost of catalysts. Among them, Ag1Pd1 sample showed nice performance of recycle test and long lifetime for the decomposition of formic acid at room temperature.
