Abstract
Anisotropic nanocatalysts have attracted a considerable attention in comparison to bulk/nano catalysts for their enhanced activity and reactivity. The demand towards anisotropic palladium (Pd) nanostructures have been increased rapidly in the area of catalysis. Pd is a well-known active catalyst for several carbon-carbon (C-C) cross-coupling reactions, among them Suzuki-Miyaura cross-coupling reaction is one of the most versatile and dominant method for constructing the extraordinarily useful unsymmetrical biaryls and also for hydrogenation of organic contaminant like p-nitrophenol (p-NP). This paper provides a brief explanation about the controlled synthesis, characterization and catalytic activity of well defined palladium nanocubes (Pd NCs) prepared by the seed mediated method. The synthesized monodispersed Pd NCs were characterized by spectroscopic and microscopic tools such as UV-Visible, XRD, FESEM, HRTEM and EDS analyses. Pd NCs proved as an efficient catalyst for Suzuki-Miyaura cross-coupling reactions and p-NP reduction. The catalyst shows enhanced activity, greater stability and higher selectivity with remarkable recyclability upto 92% for five consecutive cycles. The catalytic performance of the synthesized Pd NCs have also studied in the reduction of the organic contaminant p-NP which showed an excellent performance screening of 99 % conversion in 6 minutes.
