Abstract: Catalysis represents a very essential aspect of chemical production and industrial growth and development. Thus, in contribution to the research efforts made towards transcending the challenges encountered by catalyst design practitioners, this review highlights some noteworthy benefits of inculcating nanotechnology (bottom-up approach) a front liner technique which have essentially facilitated present day advancements in catalysts design and promotion of green catalysis. This review takes into account the challenges and opportunities encountered at different levels in its application, taking into consideration the prospects of interplay of nanotechnology with Artificial intelligence (from the previous studies) in catalyst design, and further proposes options that will be effective towards maneuvering the challenges encountered in catalyst design and structuring. Keywords: Catalyst, Green Chemistry, Nanocatalysis.
