Catalysis holds a significant position in the field of chemistry, wherein it manifests in three distinct directions that exhibit minimal overlap: heterogeneous, enzymatic, and homogeneous. Heterogeneous and homogeneous catalysis are recognized as distinct fields championed by two scientific societies, namely solid state and molecular chemistry. Despite their differences, both domains share a common goal of seeking to enhance catalytic performance. Nanocatalysis has gained prominence as a burgeoning scientific discipline in recent times, owing to its exceptional levels of activity, selectivity, and productivity. The distinctive characteristics of nanocatalysts arise from their nanoscale dimensions, morphology, and significantly elevated surface area to volume ratio. These structural and electronic modifications distinguish them from their bulk counterparts, resulting in unique properties. At the nanoscale level, the principles of quantum chemistry and classical physics are not applicable. In materials characterised by robust chemical bonding, the degree of electron delocalization can be substantial and may exhibit size-dependent variability. The primary objective of this review is to expound upon the critical understanding of nanocatalysis, detailing how the different catalytic feature and other particle features of nanomaterials are contingent on their structure and size at an atomic level.
