  Summary of Key Advances The catalyst design has entered a new phase of sophistication. This has been advanced by the capability of producing active sites with atomic accuracy by using single-atom catalysts, intermetallics, and defect engineering. It is also backed by profound knowledge of mechanisms made possible through operando characterization that shows dynamics of catalysts under operative condition. Experiment design and catalyst optimization are now directed by predictive computational frameworks that are premised on density functional theory, microkinetic modeling and machine learning. The increasing focus on the concept of sustainability has facilitated the use of electro- and photocatalytic methods which offer routes towards decarbon based chemical production. Additionally, the interdisciplinary collaboration of basic science and applied engineering issues allow to both design rationally, conduct tests, and scale up catalysts in order to develop a synergistic strategy that involves theoretical knowledge, experimental approaches, and application procedures. 7.2 Remaining Challenges Catalyst design still has a number of challenges despite the tremendous progress. It is important to bridge the complexity gap since most computational and experimental studies are done on well-defined model systems, whereas industrial catalysts are subject to complex, multicomponent, impure, and pressure gradient conditions as well as deactivation effects. The stability of catalysts and their deactivation remain to be significant concerns. The behavior of performance under conditions of interest in the industry, such as sintering, coking, poisoning, leaching, and phase transformations, is to be explored further under long-term conditions. Selectivity in complex reactions has not been easily attained, especially in reactions like the reduction of CO 2 or biomass whereby there are various competing pathways.

Lastly, testing on catalysts needs to be standardized and reproducible, particularly in developing directions such as electrocatalytic nitrogen reduction, where the protocol and benchmarking are still absent. 7.3 Emerging Opportunities The area of catalysis is experiencing a number of exciting opportunities.

  offer advancements Over recent decades, there has been significant progress in the development of catalyst dynamic transformation, encompassing the exploration of the origins, underlying principles, identification methods, and targeted tailoring of the dynamic transformations. These substantial potential for engineering the dynamic transformation to design efficient and durable photo/electrocatalysts. This comprehensive overview systematically explored such issues and identified several approaches and important triggering factors for the dynamic transformation and its applications in photo/electrocatalysis. It should be noted that reconstruction of catalysts is induced by single atom dopants, defects (vacancies, dopants, grain boundaries, etc.), heterostructures, leaching and crystallinity, which correspond to scales ranging from the atomistic This journal is © The Royal Society of Chemistry 2024Energy Environ.
