Economically palladium decorated on m-aminophenol-formaldehyde derived porous carbon spheres for enhanced catalytic reduction of organic dyes†

Abstract

We report on the use of palladium nanoparticles (Pd NPs) immobilized on m-aminophenol/formaldehyde resin (APF)-derived porous carbon spheres (Pd@PCS), as heterogeneous catalysts for organic dye reduction reactions. The morphology, structure, surface compositions, and textural properties of the PCS and Pd@PCS catalyst were fully characterized to comprehend the excellent catalytic efficiency of Pd@PCS composites. It is revealed that Pd NPs with an average particle size of ca. 12 ± 0.8 nm were highly dispersed on the surface of PCSs possessing surface area and pore volume as high as 896.3 m2 g−1 and 0.934 cm3 g−1, respectively. The prepared catalysts were applied to the reduction of various organic dyes, and the results exhibited the high catalytic activity towards crystal violet (CV), eosin yellow (SY) and sunset yellow (SY). More importantly, the catalysts can be easily recovered, and reused for many times with good stability. Therefore, the robust material that was utilized for the treatment of waste water containing organic dyes showed the potential to be widely used for environmental applications.
