Self-reduction of gold on activated carbon cloth
Activated carbon cloths (ACCs) were used as a support for preparation of Au nanoparticles. Pretreatment of ACCs was performed by using oxidizing agent HNO3 in order to introduce surface oxygen complex. Au nanoparticles were prepared by impregnation of tetrachloroauric acid (HAuCl4) without reducing...
