Abstract

The rational design of heterogeneous catalysts through framework-based approaches has emerged as a transformative strategy for controlling reaction pathways and enhancing catalytic efficiency. This paper examines recent advances in the optimization of catalytic performance through engineered frameworks, including metal-organic frameworks (MOFs), zeolites, and related porous materials. By integrating computational methods with experimental validation, researchers have achieved unprecedented control overactive site architecture, reactant confinement, and elementary reaction steps. This work reviews the fundamental principles of framework-based catalyst design, including active site engineering, confinement effects, and pore functionality, and explores computational approaches for reaction pathway engineering, encompassing density functional theory (DFT), microkinetic modeling, and multiscale simulation workflows. Experimental strategies for framework synthesis and characterization are also discussed, together with case studies of successful pathway engineering in oxidation, hydrogenation, and carbon dioxide conversion reactions. Key advances in single-atom catalysis, bimetallic site engineering, bridging-atom modification, and operando mechanistic studies are highlighted, demonstrating how atomic-level structural control translates into substantial gains in catalytic activity and selectivity. Emerging concepts such as stimuli-responsive catalysis, cascade reactions, and interface engineering are considered as promising directions for expanding the scope of achievable transformations. Finally, current challenges are outlined, including framework stability under harsh reaction conditions, mass transport limitations, computational accuracy, cost, and scale-up economics, alongside future opportunities involving machine learning-accelerated catalyst discovery and advanced operando characterization in this rapidly evolving field.

Keywords: Catalysis, MOF (metal-organic frameworks), framework-based catalyst, Engineering, DFT (density functional theory).
