“…For 2D Co-doped MoS 2 crystal, the difference of electronegativity between Mo and Co creates a forceful polarization that served as an efficient charge transfer path along polarization direction of monolayer plane. [114] Annealing treatment on BaTiO 3 can induce the thermal motion and alter the polarization of [TiO 6 ] octahedron (Figure 10a,b). The annealed BaTiO 3 at 800 °C with stronger tetragonal distortion demonstrated the strongest ferroelectric polarization; thus the piezocatalytic activity of this treated sample was the highest in comparison with BaTiO 3 annealed at other temperatures.…”

Piezoelectric-based catalysis that relies on the charge energy or separation efficiency of charge carriers has attracted significant attention. The piezo-potential induced by strain or stress can induce a giant electric field, which has been demonstrated to be an effective means for charge energy shifting or transferring electrons and holes. In recent years, intense efforts have been made in this subject, and the research has mainly focussed on two aspects: i) Alteration of surface charge energy by piezo-potential in piezocatalysis; ii) the separation of photo-generated charge carriers and the catalytic activity enhancement of an integrated piezoelectric semiconductor or coupled system composed of piezoelectrics and semiconductors. Systematically summarizing the advances of the above two aspects is helpful in the context of deepening understanding of the relevant issues and developing new ideas for piezoelectric-based catalysis. In this review, a comprehensive summary on piezocatalysis and piezo-photocatalysis is provided. The charge transfer behaviors and catalytic mechanisms over a large variety of piezocatalysts and piezo-photocatalysts are systematically analyzed. In addition, the types of mechanical energy, strategies for enhancing piezocatalysis, and the advanced applications of piezocatalysis and piezophotocatalysis are discussed. Finally, the promising development directions of piezocatalysis and piezo-photocatalysis, such as materials, assembly forms, and applications in the future are proposed.

Ferro-, piezo-, and pyroelectric materials are emerging as potential candidates for converting various forms of primary energy from the ambient environment (e.g., sunlight, mechanical, and thermal energy) into secondary energy (e.g., chemical energy). Despite the relatively short investigation time, much progress has been made related to this field. This review covers the fundamental principles of coupling ferro-, piezo-, and pyroelectric effects with different catalytic reactions; the crucial role of a polarization-induced internal electric field in charge separation and transport in these materials is discussed. We particularly focus on recent notable examples of using these three types of nanostructured materials for a variety of catalytic applications in the fields of renewable energy production (e.g., water splitting and CO 2 reduction), environmental remediation (e.g., organic pollutant decontamination), and materials synthesis (e.g., selective growth/deposition and organic synthesis). Finally, we conclude this review by proposing critical challenges and future perspectives for developing ferro-, piezo-, and pyroelectric nanomaterial-based catalysts for efficient energy harvesting.
