Herein, a simple one-pot aqueous method was developed for synthesis of AgPt hollow alloyed nanostructures (AgPt HANS) with polyvinylpyrrolidone (PVP) and cytosine as the dispersing agent and eco-friendly growth-director, respectively. The synthesized architectures displayed the improved catalytic performance toward ethylene glycol oxidation reaction (EGOR) relative to commercial Pt black in alkaline media. Meanwhile, the catalyst exhibited the enhanced catalytic activity for hydrogen evolution reaction (HER) with the positive onset potential (E-onset, -39 mV) and a small Tafel slope (40 mV dec(-1)) relative to commercial Pt/C (20 wt%, -31 mV, 33 mV dec(-1)) in 0.5 M H2SO4, along with the more positive Eonset (-34 mV) and a smaller Tafel slope (59 mV dec-1) in 0.5 M KOH compared with Pt/C (-35 mV, 85 mV dec(-1)).
