Abstract The fabrication of reusable SERS substrates with sensitivity at the single‐molecule level remains challenging but promising. Herein, a composite surface‐enhanced Raman scattering (SERS) substrate is proposed that includes Ag nanoparticle (Ag NPs) /Graphene/BaTiO 3 (Ag/G/BTO) from chemical enhancement perspective. pyroelectric field generated by BaTiO drives charge transfer between and molecules, achieving significant improvement in performance self‐cleaning properties. signals rhodamine 6G (R6G) molecules are further amplified up to 70‐fold. Thus, detection limit reduced three orders magnitude this study, reaching 10 −14 m after applying field. In addition, exhibits higher degradation efficiency than previous because outstanding catalytic properties . Target degraded effectively several temperature cycles. A detailed mechanism analysis conducted based on theoretical simulations experimental results. This study considered deepen understanding mechanisms boost application technology.

Directly transforming solar energy into chemical compounds via photocatalytic water splitting can continually producing hydrogen, regarded as one of the ultimate sustainable sources. The key point achieving high photoelectrochemical (PEC) performance depends on successful design and synthesis high-efficient photocatalysts. However, slow separation fast recombination photo generated charge carriers greatly limit utilization energy, resulting in low PEC efficiency. Recently, piezoelectric/pyroelectric effect assisted brings new sight improving charger separate transfer behaviors. In this review, recent advancements state-of-the-art progress are summarized discussed. Different types photocatalysts classified according to their constitutions corresponding advantages each type also Furthermore, coupling piezoelectric pyroelectric system is introduced. Finally, prospects, critical challenges promising strategies for application materials highlighted.
