Reverse construction of dominant/secondary facets in Bi24O31Br10 photocatalysts for boosting electronic transfer

Abstract

In this paper, it is found that the preferential growth of secondary {117} facets of Bi₂₄O₃₁Br₁₀ into dominant facets would lead to higher photocatalytic activity, although the original main {213} facet has a stronger molecular oxygen adsorption ability, which illustrates that the charge separation efficiency induced by dominant/secondary facet control plays a more important role than that of O₂ adsorptive performance in improving activity.
