Abstract
Nanocatalysis represents a burgeoning field of study that is used across a
wide range of catalytic organic reactions. The significance of nanotechnology is
progressively growing in various industrial sectors as well as in academic research. The
enhancement of catalytic selectivity and activity in nanocatalysts is observed as the size
of the catalyst decreases and the surface area-to-volume ratio increases. Similarly, the
morphology of particles plays a crucial role in influencing the activity and selectivity of
nanocatalysts. Various types of nanocatalysts have been documented, encompassing
single-metal nanocatalysts, simple/mixed metal-oxide derived nanocatalysts, and
carbon-based nanocatalysts. Nanocatalysts based on noble, rare earth and transition
metals have been extensively investigated in both industrial and academic areas. This is
primarily due to their significant application in various chemical reactions, including
carbon-heteroatom cross-coupling reactions, carbon-carbon homocoupling reactions,
carbon-carbon cross-coupling reactions, esterification, C-H activation, hydrogenation,
oxidation, and reduction. Currently, the analysis is centered on most recent
advancements and potential applications of nanocatalysts in various chemical
processes.
