Abstract
A nitrogen doped BiOCl (N‐BiOCl) photocatalyst was synthesized and characterized using an ethylenediamine‐assisted hydrothermal method. The N‐BiOCl sample demonstrated the same tetragonal crystal structure as the as‐prepared pure BiOCl sample. SEM results indicated that N‐BiOCl sample was self‐assembled by nanoplates to provide an aggregated flower‐like microstructure. Doped nitrogen was substituted for oxygen in the crystal lattice of BiOCl, causing a red shift for N‐BiOCl sample compared to BiOCl sample. The N‐BiOCl sample exhibited higher photocatalytic activity in the degradation of Rhodamine B under visible light than observed in BiOCl sample, and the stability of the sample was verified. Meanwhile, speculative causes for the enhancement in the photocatalytic activity of N‐BiOCl sample were also proposed.
