Herein, we report a facile one-step synthesis route of porous bimetallic Au-Ag nanoparticles involving two parallel processes: alloying during nanocrystal growth and dealloying via galvanic replacement reaction. Further, we show that porosity in these nanoparticles can be tuned via their alloy composition. The specific surface area of the synthesized porous nanoparticles is significantly enhanced compared to that of their solid bulk counterparts.
