文摘
- •
The Pt catalysts supported on CQD/RGO hybrids are prepared by one pot method.
- •
Pt nanoparticles around 2–3 nm disperse uniformly on substrate.
- •
More than 2 times mass activity and 3 folds specific activity of Pt/C in MOR.
- •
Clear tendency of the improving MOR performance with the increasing content of CQD.
- •
Enhanced performance roots in the multibenefits from the adding of CQD.
