▎ 摘 要
Herein, we report the synthesis of multimetallic core-satellite nano-dendrites (Pt@Au@rGO) composed of nano-sized reduced graphene oxide (50-60 nm) wrapped gold nanoparticles (30 nm) as the core and ultra-small platinum nanoparticles as the satellites. These were then used as a highly active catalyst for CO2 photoreduction to HCOOH (quantum yield = 1.95%, chemical yield = 3.31%) with excellent reusability and colloidal stability.
