As a two dimensional (2D) visible-light-responsive semiconductor photocatalyst, the photoreactivity of Bi 2 WO 6 is not high enough for practical application owing to its limited response to visible light and rapid recombination of photogenerated electron-hole pairs. In this paper, 2D core-shell structured Bi 2 WO 6 @Bi 2 S 3 nanoplates were prepared by calcination of a mixture of Bi 2 WO 6 (1.3 g) and a certain amount of Na 2 S·9H 2 O (0–3.0 g) at 350 °C for 2 h. The reactivity of the resulting photocatalyst materials was evaluated by photocatalytic degradation of Brilliant Red X-3B (X3B), an anionic dye, under visible light irradiation ( λ > 420 nm). As the amount of Na 2 S·9H 2 O was increased from 0 to 1.5 g, the degradation rate constant of X3B sharply increased from 0.40 × 10 −3 to 6.6 × 10 −3 min −1 . The enhanced photocatalytic activity of Bi 2 WO 6 @Bi 2 S 3 was attributed to the photosensitization of Bi 2 S 3 , which greatly extended the light-responsive range from the visible to the NIR, and the formation of a heterojunction, which retarded the recombination rate of photogenerated electron-hole pairs. However, further increases in the amount of Na 2 S·9H 2 O (from 1.5 to 3.0 g) resulted in a decrease of the photocatalytic activity of the Bi 2 WO 6 @Bi 2 S 3 nanoplates owing to the formation of a photo-inactive NaBiS 2 layer covering the Bi 2 WO 6 surface.

Representative biomarkers (e.g., n-alkanes), diversity and microbial community in the aquifers contaminated by high concentration of arsenic (As) in different sediment depth (0–30 m) in Jianghan Plain, Hubei, China, were analyzed to investigate the potential mechanism of As enrichment in groundwater. The concentration of As was abundant in top soil and sand, but not in clay. The analysis of the distribution of n-alkanes, CPI values, and wax to total n-alkane ratio (Wax(n)%) indicated that the organic matter (OM) from fresh terrestrial plants were abundant in the shallow sediment. However, n-alkanes have suffered from significant biodegradation from the depth of 16 m to 30 m. The deposition of fresh terrestrial derived organic matters may facilitate the release of As from sediment to groundwater in the sediment of 0–16 m. However, the petroleum derived organic matters may do the favor to the release of As in the deeper section of borehole (16 m to 30 m). The 16S rRNA gene sequences identification indicated that Acidobacteria, Actinomycetes and Hydrogenophaga are abundant in the sediments with high arsenic. Therefore, microbes and organic matters from different sources may play important roles in arsenic mobilization in the aquifers of the study area.
