- •
The growth of Cu NPs was accomplished by one-step calcination at 560 °C.
- •
The graphene acted as reductant to obtain the conversion of CuO to Cu NPs.
- •
Ni@GE-Cu showed excellent catalytic activity for the reduction of Cr(VI).
- •
The magnetically separable Ni@GE-Cu was very cheap, scalable and recyclable.
