文摘
- •
Au nanoparticles were embedded in polypyrrole (PPy) chains on the surface of fly ash (FA) by a green, one-pot strategy.
- •
The Au-PPy/FA composite 15performed high efficiency in catalytic reduction of nitrophenol to corresponding aminophenol with NaBH4 as reducing agent.
- •
A possible reaction mechanism is proposed to explain the enhanced catalytic efficiency of Au-PPy/FA.
