Summary: The poor activity of MoS2 basal plane limits efficient hydrogen production. Single and double sulfur vacancy MoS2 (VS-MoS2 and VS, S-MoS2) were used for water gas shift reaction (WGSR). The adsorption energy of VS, S-MoS2 for CO molecule is significantly higher than that of original MoS2 and VS, S-MoS2. The energy barrier of the rate-determining step in the association mechanism of VS, S-MoS2 is lower than pristine MoS2.

Summary: In this study, BiOCl and BiOBr photocatalysts with abundant O vacancies were synthesized for photocatalytic reduction of nitrogen to ammonia. The results showed that the ammonia generation rates of BiOCl and BiOBr with O vacancies were significantly higher than those of pure BiOCl and BiOBr.
