Carbon nanotubes (CNTs) make as an ideal candidate for supporting material due to their outstanding physical properties, such as the ultra-high surface area, high mechanical strength, and also high chemical and thermal stability. Aromatic nitro compounds are the pollutants in wastewater. Pd-based compounds have high catalytic activity for the reduction of aromatic nitro compounds. By the way, the applications of Pd nanoparticles remain limited by weakness in terms of their easy aggregation and the difficulty of catalyst product separation. In this study, we synthesized Pd and Ni(OH)2-decorated CNT by introducing amine groups on CNTs. To study the catalytic activity, a 1ⅹ10-3 M of aqueous nitrophenol solution was mixed with 0.1 M of fresh NaBH4 solution. The CNT-Pd/Ni(OH)2 catalysts were added and stirred. The mixture was immediately transferred into a quartz cuvette and UV-vis absorption spectra were recorded to monitor changes in the reaction mixture. |
