Abstract

The rational design of catalytic materials that simultaneously achieve high activity, selectivity, and durability under realistic operating conditions remains a grand challenge. At the atomic and molecular levels, catalytic transformations proceed through complex, multistep pathways that couple proton–electron transfer events, competitive adsorption phenomena, and the dynamic restructuring of active sites. These processes are inherently multiscale, spanning localized electronic interactions, mesoscale reorganization of active surfaces, and reactor-level transport phenomena. Over the past century, advances in surface science, quantum chemistry, and operando characterization have significantly advanced our mechanistic understanding of catalysis. Nevertheless, theoretical frameworks and experimental approaches have often evolved in parallel rather than in concert, with each probing specific spatial or temporal domains in isolation. This lack of integration hinders the development of a coherent, predictive picture of catalytic processes that can effectively inform design strategies.

To bridge these gaps, we propose the concept of “spatiotemporal control” as a holistic framework that integrates catalytic research across multiple scales. This framework emphasizes the coupled nature of spatial dimensions-ranging from the atomic to the reactor scale-and temporal regimes, spanning ultrafast electron transfer on the picosecond scale to slow structural evolution over seconds or longer. Within this perspective, our group have been focusing on key topics including the origins of spatial and temporal complexity in heterogeneous electrocatalysis; statistical physics approaches that connect atomistic and mesoscale processes; and the interplay of equilibrium and non-equilibrium dynamics across temporal regimes. Finally, we highlight how spatiotemporal control can guide the design of next-generation catalytic systems, advancing clean energy and industrial applications while accelerating their translation from fundamental discovery to scalable technology.
