Modifications in Subsurface of Catalysts: Impact of Bringing in Electrophilicity on Catalytic Applications

Abstract Surface, interface, and subsurface in catalysts are broadly perceived as independent units in materials, relying on diverse bonding environments and are recurrently studied discretely because of experimental challenges in distinguishing the surface and subsurface effects. Metal crystals, isolated atoms, or metal nanoparticles in supported catalysts induce an electrophilic nature in subsurface, enhancing the catalysis efficiency. In this review, the influence of modification in subsurface of catalysts and their specific catalytic outputs are discussed. Key approaches and techniques for insertion of subsurface modifications and impact of electrophilicity upon catalysis upgradation are observed. A compilation of frequently used chemical reactions catalyzed by subsurface‐modified catalysts have been structured and thoroughly illustrated.
