Nano‐heterointerface engineering has been demonstrated to influence interfacial polarization by expanding the interface surface area and constructing a built‐in electric field (BEF), thus regulating electromagnetic (EM) wave absorption. However, the dielectric‐responsive mechanism of the BEF needs further exploration to enhance the comprehensive understanding of interfacial polarization, particularly in terms of quantifying and optimizing the BEF strength. Herein, a “1D expanded 2D structure” carbon matrix is designed, and semiconductor ZnIn2S4 (ZIS) is introduced to construct a carbon/ZIS heterostructure. The cross‐dimensional nano‐heterointerface design increases interface coupling sites by expanding the interface surface area and induces an increase in the Fermi level difference on both sides of the interface to modulate the distribution of interface charges, thereby strengthening the BEF at the interface. The synergistic effect leads to excellent EM absorption performance (minimum reflection coefficient RCmin = −67.4 dB, effective absorption bandwidth EAB = 6.0 GHz) of carbon/ZIS heterostructure. This work introduces a general modification model for enhancing interfacial polarization and inspires the development of new strategies for EM functional materials with unique electronic behaviors through heterointerface engineering.

Piezocatalysis and piezo‐photocatalysis technology is a continuously developing catalytic technology based on the piezoelectric effect of catalysts, which breaks the barrier between mechanical and chemical energy. The piezoelectric polarization field formed by the mechanical deformation of piezoelectric materials is proven to effectively manipulate band structures, improve the separation of electron‐hole pairs and enhance the catalytic activity, thus alleviating energy crises and environmental issues. Herein, this review first introduces the technology of piezocatalysis and piezo‐photocatalysis, comprehensively summarizes the synthesis methods of piezo(photo)catalysis materials, and analyzes and discusses the measures to optimize the performance of piezo(photo)catalysts. The following systematically summarizes the characteristics and development of the current main piezo(photo)catalytic systems, and discusses the application of first principles calculations in piezo(photo)catalysis in combination with practical researches. Subsequently, the main application progress of piezo(photo)catalysis in environmental remediation, energy conversion, and biomedical therapy fields is presented. In the end, the current challenges, development direction, and future prospects are prospected.

The sustainable future relies on the synergistic development of energy, environmental, and electronic systems, founded on the development of functional materials by exploring their quantum mechanisms. Effective control over the distribution and behavior of charges within these materials, a basic quantum attribute, is crucial in dictating their physical, chemical, and electronic properties. At the core of charge manipulation lies “polarization”—a ubiquitous phenomenon marked by separating positive and negative charges. This review thoroughly examines polarization techniques, spotlighting their transformative role in catalysis, energy storage, solar cells, and electronics. Starting with the foundational mechanisms underlying various forms of polarization, including piezoelectric, ferroelectric, and pyroelectric effects, the perspective is expanded to cover any asymmetric phenomena that generate internal fields, such as heterostructures and doping. Afterward, the critical role of polarization across various applications, including charge separation, surface chemistry modification, and energy band alignment, is highlighted. Special emphasis is placed on the synergy between polarization and material properties, demonstrating how this interplay is pivotal in overcoming existing technological limitations and unlocking new functionalities. Through a comprehensive analysis, a holistic roadmap is offered for harnessing polarization across the broad spectrum of applications, thus finding sustainable solutions for future energy, environment, and electronics.
