“…pointed out two principal mechanisms behind such acceleration: the freeze‐concentration effect and the freeze‐potential effect. [ 35 ] When a pure component freezes, as illustrated in Figure A, the process occurs sharply. Instead, in impure solutions or mixtures, freezing can occur over a range of temperatures.…”

“…This effect is crucial as the generated electrical gradients can act as driving forces for specific reactions, modulating the overall reactivity within the icy matrix. [ 35 ] Initially documented by Workman and Reynolds, [ 38 ] it is rooted in the differential rates at which solute ions are excluded during ice formation, creating an imbalance of charges between the ice crystals and the unfrozen solution. This electric potential difference can range from +214 to −90 V (the sign of the potential refers to the ice), contingent upon the nature of ions and their concentrations.…”

“…[19] Additionally, as ice crystals grow within the liquid, a solute exclusion phenomenon emerges: the ice crystals push solutes in the liquid, whether they are particulate or dissolved substances, to unfrozen regions, leading to enriched zones or specific channels. [35] Together, these distinctive physicochemical properties position ice as a fascinating medium for exploring novel avenues in both chemical reactions and material assemblies. Meanwhile, they shed light on the intricate mechanisms that ice-mediated reactions and assemblies often present.…”

In chemistry, biology, and materials science, ice‐mediated reactions and ice‐template assembly techniques are garnering increasing attention due to their unique advantages. Such approaches not only offer deep insights into the fundamental roles of ice in nature but also pave new avenues for various applications. This review comprehensively explores the mechanisms and applications of ice‐mediated reactions and assembly. It begins by examining the principles of ice‐mediated reactions, particularly how certain chemical reactions are accelerated in the micro‐environment of ice through freeze‐concentration and freeze‐potential effects, and the relationship between the surface structure and properties of ice and chemical reactions. This work then studies significant chemical reactions within the realms of environmental, biological, and materials science engineering, shedding light on the role of ice in these reactions. Furthermore, this work explores the fundamentals of ice templating in material assembly, describe the main ice‐templating methods, and highlight the ice‐templated materials along with their diverse applications. This work concludes by summarizing the prospective challenges and untapped potentials in the field of ice‐mediated reactions and assembly. This review not only accentuates the transformative impact of ice‐mediated techniques in scientific domains but also serves as an useful guide for future research initiatives and practical applications in this burgeoning field.
