The highly efficient BiOIO₃/g-C₃N₄ with unique nanoflake heterostructures were synthesized through hydrothermal method by simply depositing BiOIO₃ flake on the surface of g-C₃N₄. Photocatalytic ability of nanoflakes was tested by oxidation of gaseous Hg⁰ under 18 W and 24 W LED light irradiation. The g-C₃N₄/BiOIO₃ composite with the molar ratio of 10:1 exhibited that the Hg⁰ removal efficiency reached up to 93.7%. The remarkable photocatalytic performance of the as-prepared catalysts can be attributed to the interfacial contact heterostructure formed between BiOIO₃ and g-C₃N₄, which constructs an intimate interfacial interaction between the two components. Moreover, well-matched band structure can efficiently lead to the separation of photogenerated charges.

高效BiOIO ₃ / GC ₃ Ñ ₄具有独特的纳米片的异质结构是通过水热法通过简单地沉积BiOIO合成₃的GC表面薄片₃ Ñ ₄。通过在18 W和24 W LED光照射下气态Hg ⁰的氧化测试了纳米薄片的光催化能力。摩尔比为10：1的gC ₃ N ₄ / BiOIO ₃复合材料表现出Hg ⁰去除效率达到93.7％。所制备的催化剂具有显着的光催化性能，这可以归因于BiOIO ₃和gC ₃ N ₄之间形成的界面接触异质结构，这在两种组分之间建立了紧密的界面相互作用。而且，良好匹配的能带结构可以有效地导致光生电荷的分离。
