Halide perovskite-based nanomaterials for the detection and photocatalytic removal of gaseous pollutants

Abstract

Halide perovskite-based nanomaterials have attracted considerable attention in the field of detection and photocatalytic removal of gaseous pollutants. These nanomaterials not only exhibit a strong response to visible light and good photocatalytic activity but also demonstrate high sensitivity and selectivity in the detection of gaseous pollutants. Consequently, they are expected to play a significant role in photocatalysis and pollutant gas detection. Despite their promising application potential, halide perovskite-based nanomaterials face challenges such as low stability, insufficient active sites, and low carrier migration effectiveness. In this review, we comprehensively discussed the research on halide perovskites for the photocatalytic removal of nitrogen oxides and volatile organic compounds (VOCs), and halide perovskites as gas sensors for gaseous pollutant detection as well as the related mechanism. Finally, we clarified the challenges and future prospects of these materials, providing new insights for advancing the development of halide perovskites in gaseous pollutant detection and photocatalytic removal.
