Abstract

AbstractRecent developments in heterogeneous nanocatalysis have illustrated the great strides metal nanoparticles (NPs) have made due to their several significant features. However, the major lingering challenge has been their deactivation in organic reactions by migration‐coalescence largely due to their high surface energy. In this context, various supports materials have been designed to overcome the stability issues for metal NPs. Furthermore, the activity and selectivity could be simultaneously enhanced by taking advantage of the synergy between the metal NPs and the support material, like abundantly available inexpensive polystyrene resins (PSR). Herein, the recent developments on PSR‐supported catalysts are deliberated for assorted organic reactions conducted under sustainable conditions. The salient advantageous attributes of nanocatalyst‐adorned PSR are discussed in terms of their activity, recyclability, stability and selectivity for various organic transformations. Further, the enduring challenges associated with the PSR‐supported nanocatalysts and future perspectives for further developments are explicated.
