One-pot synthesis of porous Pt–Au nanodendrites supported on reduced graphene oxide nanosheets toward catalytic reduction of 4-nitrophenol

A facile, green and effective one-pot wet-chemical co-reduction method was developed for preparation of Pt–Au pNDs/RGOs in the presence of cytosine. The nanocomposites exhibited significantly enhanced catalytic performance for 4-nitrophenol reduction.
