چکیده
|
In this work, pd nps supported on amine-modified natural hematite have been prepared and characterized. using this simple catalyst, nitroaromatic compounds as a major cause of industrial pollution were reduced to corresponding amines with ppm levels of pd in the presence of designer surfactant tpgs-750-m and nabh4 at room temperature in aqueous media. synergistic effect between hematite and pd is responsible for the observed enhanced catalytic activity. this catalyst was recycled for at least four times with a small decrease in the activity.
