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.
