Catalysts

     Noble metals supported on porous carbon atoms have attracted considerable attention owing to their potential applications as catalysts.The reduced particle size greatly enhances the surface-to-volume ratio, and facilitates the catalytic performance of the noble metals. However, the smallsized metal nanoparticles (MNPs) bring about some inevitable problems in separation and recycling. To overcome this difficulty, many efforts have been devoted to immobilize MNPs onto the surface of various solid supports.In past decades, palladium nanoparticles (Pd NPs) supported on porous carbon spheres (PCS) have shown fascinating catalytic activity for various organic reactions, electrochemical, and dye-sensitized solar cells (DSSC) applications.

     Due to their unique properties, Pd-based carbon nanomaterials exhibit high thermal stability, good electrochemical activity, solvent resistance, large surface area, low pollution and ease of recycling, thereby attracting a wide range of applications in materials sciences and chemistry.Recently, carbon-supported Pd NPs have been demonstrated to be a viable way of removing dyes and other organic pollutants from the environment.
