Synthesis of BiOCl nanosheets with exposed (010) facets via a facile two-phase reaction and photocatalytic activity

ABSTRACT

BiOCl nanosheet (NSs) with exposed (010) facets have been successfully synthesized via a facile diffusion process at water-air interface at room temperature. The X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results confirm the formation of octagonal BiOCl NSs with exposed (010) facets. BiOCl photocatalyst with exposed (010) facets exhibits higher photocatalytic activity than BiOCl photocatalyst with exposed (001) facets under UV light irradiation. This novel photocatalyst demonstrates potential application for organic pollutant elimination and proposes insights for designing highly efficient BiOCl based photocatalysts.
