合成了二维BiOI纳米板，并将其作为铂纳米颗粒沉积的载体。由于铂-BiOI电极具有较宽的可见光吸收范围(最大可达660 nm)，可作为有效的光电催化剂应用于碱性介质中可见光催化乙醇的氧化。与黑暗条件相比，在可见光照射下，铂-BiOI修饰电极对乙醇氧化的催化活性提高了3倍。电催化和光催化的协同效应以及二维结构的独特性有助于催化活性的提高。提出了强化光电催化过程的机理。结果表明，二维可见光激活的BiOI可以作为铂修饰的良好载体，并可应用于光电化学和光助燃料电池领域
Two dimensional (2D) BiOI nanoplates were synthesized and used as support for the deposition of Pt nanoparticles. Owing to broad visible light absorption (up to 660 nm), the as-obtained Pt–BiOI electrode was used as effective photoelectrocatalyst in the application of catalytic ethanol oxidation in alkaline media under visible light irradiation. Compared to dark condition, the Pt–BiOI modified electrode displayed 3 times improved catalytic activity towards ethanol oxidation under visible light irradiation. The synergistic effect of electrocatalytic and photocatalytic, and the unique of 2D structures contribute to the improvement of catalytic activity. The mechanism of enhanced photoelectrocatalytic process is proposed. The present results suggest that 2D visible-light-activated BiOI can be served as promising support for the decoration of Pt and applied in the fields of photoelectrochemical and photo–assisted fuel cell applications
