Significant production of elemental bromine (Br₂) was observed for the first time when treating bromide containing solutions at acidic pH, with TiO₂ photocatalyst, ozone, or a combination thereof. Br₂ selectivities up to approximately 85 % were obtained and the corresponding bromine mass balance values satisfied. The process is general and may be applied at a laboratory scale for green bromination reactions, or industrially as a cheap, safe, and environmentally sustainable alternative to the currently applied bromine production methods.

TiO2光催化和/或臭氧化生产元素溴

当用TiO ₂光催化剂，臭氧或其组合处理酸性pH值的含溴溶液时，首次观察到大量元素溴（Br ₂）的产生。获得的Br ₂选择性高达约85％，并且满足了相应的溴质量平衡值。该方法是通用的，可以在实验室规模上用于绿色溴化反应，或在工业上作为当前应用的溴生产方法的廉价，安全和环境可持续的替代方法。
