Abstract
This study demonstrated a rapid method of producing PtPd via chemical reduction by varying metal composition and types of capping agents. The effect of different compositions between the two-metal precursor, Pt and Pd, is invested by tuning at various volume ratios of 3:1, 1:3, and 1:1 and comparing them with their single counterparts. The FESEM results show that all prepared samples exhibit nanosponges structure. PtPd of 1:1 ratio has the highest ECSA of 14.25 m2 /g, while PtPd with PVP exhibits a high ECSA value of 692.7 m2 /g compared to those without capping agent (287.8 m2 /g), indicating large active sites, which increases its catalytic function.
