Metal-sulfide hybrid nanocrystals(HNCs)have been of great interest for their distinguished interfacial effect,which gives rise to unique catalytic properties.However,most of the reported metal-sulfide HNCs were synthesized via two-step approaches and few were fabricated based on the one-step strategies.Herein,we report a facile one-pot synthesis of CuPt-Cu2S,Pt-Cu2S HNCs,and CuPt nanocubes by simply changing the Pt precursor types.
