The unique 3D architecture of pyrrolo[3,2-<i>b</i>]pyrroles is reflected in the curved forms of the clouds and the warped flying carpet. Their main feature, photophysical properties, is symbolized by the emission of light from the pyrrolopyrrole-embedded 3D molecules, illuminating the carpet. Persian carpets are widely recognized as a primary cultural symbol of Iranian handicrafts, and the stylized clouds, inspired by the Persian miniature art, together highlight the scientific theme through a culturally rich and imaginative lens. The overall atmosphere of the image can somewhat evoke “Tales from the One Thousand and One Nights” (a collection of Middle Eastern folktales).

This review is structured into three major categories based on catalyst type: homogeneous, heterogeneous, and nanoparticle-supported catalyst. Each section is further divided into direct hydrogenation, transfer hydrogenation, and dehydrogenation reactions, covering a wide range of substrates including alkynes, alkenes, carbonyl compounds, nitroarenes, amines, and alcohols. Structure–activity relationships, mechanistic pathways, and chemoselectivity trends are critically analyzed to provide insights into the role of nickel in these transformations.
